Yes. I found several Chicago-area agencies that look particularly relevant if you need both nonprofit experience and serious accessibility expertise, rather than a generic agency that merely says it can make an ADA-compliant site.

My strongest shortlist

• Mightybytes — Probably my first call. Chicago-based, mission-driven organizations are a core focus, and they state that their deliverables meet WCAG 2.2 AA by default. They also offer accessibility audits, remediation, training, and manual testing with people using assistive technologies. Mightybytes

mightybytes.com

• Sandstorm Design — Strong fit for a disability-focused nonprofit because they combine nonprofit/purpose-driven work with inclusive design and accessibility. Their accessibility work includes audits, remediation, and training.

sandstormdesign.com

• Windy City Web Solutions — Worth considering if you're looking for a smaller, hands-on shop and a WordPress site. They specifically market accessible websites for Chicago nonprofits and have documented work for nonprofits including Nourishing Hope and United Way of Lake County. Windy City Web Solutions

windycitywebsolutions.com

• Firebelly Design — Chicago agency with a long history of donating design services to nonprofits through its Grant for Good program. Their web capabilities include accessibility compliance, UX, information architecture, and development.

firebellydesign.com

• LimeRed Studio, Inc. — A good option if you need branding + website + accessibility, particularly for a mission-driven organization. Their services include web development, UX/UI, accessibility auditing, SEO, and WordPress.

limeredstudio.com

• Dialogue Theory — Smaller Chicago studio focused on mission-driven organizations, nonprofits and civic work. Accessibility and inclusive design are part of its stated focus.

dialoguetheory.com

• Promet Source — Particularly interesting if you need a larger, technically sophisticated Drupal/WordPress build. They work with mission-driven organizations and emphasize accessibility, governance and compliance.

prometsource.com

• Clique Studios — Chicago digital agency with nonprofit experience and capabilities spanning UX/UI, accessibility, usability testing, WordPress and Drupal. This is more of a full-service agency option.

clique.is

Also worth contacting

Orbit Media Studios is another particularly credible Chicago option. They have substantial nonprofit experience—including work with the Greater Chicago Food Depository—and explicitly discuss accessibility for people with visual and mobility impairments, including WCAG/Section 508 testing and testing with actual users.

Project6 is worth a look if you're comfortable considering an agency beyond the immediate Chicago core. It specializes in foundations/nonprofits and says most of its nonprofit clients need WCAG 2.2 AA compliance. Project6

One especially interesting option

Elevation specializes exclusively in nonprofit websites and now explicitly builds to WCAG 2.2 AA, with accessibility audits, remediation, monitoring and staff training. Its site specifically describes designing for both donors and people using screen readers. Elevation Designs Elevation Designs

elevationweb.org

Who I'd contact first

For a disability-focused nonprofit, I'd start with:

1. Mightybytes — strongest combination of Chicago + mission-driven work + accessibility maturity.
2. Sandstorm Design — especially good if inclusive design and UX research are important.
3. Windy City Web Solutions — potentially attractive for a smaller-budget WordPress project.
4. Orbit Media — strong established agency with demonstrated nonprofit and accessibility experience.
5. LimeRed Studio — good if the project also involves branding/messaging.
6. Elevation — excellent accessibility/nonprofit specialization, though I'd confirm their current Chicago-area project availability.

One thing I'd specifically ask each agency: “Can you show us two or three nonprofit sites you've built where accessibility was a primary requirement, and explain how people with disabilities participated in testing?” That's a much better filter than simply asking whether they are “ADA compliant.”

Yes. I found several Chicago-area agencies with specific evidence of accessibility work and/or disability-focused nonprofit experience. I’d prioritize these:

1. Mightybytes — Strongest overall fit

• Chicago-based, mission-driven digital agency.
• Says its deliverables meet WCAG 2.2 Level AA by default.
• Offers accessibility audits, remediation, training, and manual testing with people who use assistive technology through Access Living.
• Particularly good if you want accessibility integrated into the entire design/development process rather than added at the end. Mightybytes
• mightybytes.com
• Cybernautic Web Design — Good smaller-agency option

• Chicago-based web agency offering accessible builds and ADA/WCAG-related services.
• Worth asking them specifically whether they can demonstrate manual accessibility testing, rather than relying primarily on an accessibility widget.
• cybernauticdesign.com
• Sandstorm Design — Strong for complex nonprofit/mission-driven organizations

• Chicago agency with a focus on UX, inclusive design and accessibility.
• Their accessibility work includes audits, remediation and training, and they report accessibility expertise/certification.
• A good candidate if your site has lots of content, stakeholders, or complicated user journeys.
• LimeRed Studio, Inc. — Strong nonprofit/purpose-driven fit

• Chicago-based and focused on purpose-driven organizations.
• Offers web design/development, accessibility and SEO auditing, UX, WordPress, integrations and related services.
• Particularly worth considering if you need help with strategy + content + design + development, not just coding.
• Dialogue Theory — Good mission-driven UX option

• Chicago studio working with nonprofits and civic/public-interest organizations.
• Its work emphasizes UX, usability and accessibility, which could be valuable if your users include people with different disabilities and assistive-technology needs.
• Windy City Web Solutions — Potentially good budget-conscious option

• Chicago-based and specifically markets nonprofit web design.
• Has built accessible sites for nonprofits including Nourishing Hope and United Way of Lake County. Windy City Web Solutions
• This may be a better fit than a large agency if you're a small or mid-sized nonprofit.

One agency I would contact first

Mightybytes stands out because it combines Chicago location + nonprofit/mission-driven work + explicit WCAG 2.2 AA standards + actual accessibility testing/remediation. Mightybytes

There is also an especially relevant Chicago success story: Orbit Media built a new site for Equip for Equality, an Illinois nonprofit whose mission is specifically advancing the civil and human rights of people with disabilities. The project targeted WCAG 2.1 AA, reorganized its resource library, and addressed accessibility as a core project goal. Orbit Media Studios

orbitmedia.com

That makes Orbit another agency I'd put on your shortlist if your organization is specifically disability-focused.

A particularly relevant precedent

There's an even stronger example: The Chicago Lighthouse—a Chicago nonprofit serving people who are blind, visually impaired and disabled—had its website redesigned by Briteweb to WCAG Level AAA. The project involved a very large content structure and specialized accessibility needs for blind/visually impaired users. RGD

So if you want an agency with direct experience serving a disability organization, I'd investigate Briteweb as well, even though it's not a Chicago-based agency.

What I'd ask during your first calls

Don't just ask, "Can you build an ADA-compliant website?" I'd ask:

• Have you built a site for an organization serving people with disabilities? Can I see it?
• Do you target WCAG 2.2 AA?
• Do you perform manual testing with screen readers and keyboard-only users?
• Do people with disabilities participate in your usability/accessibility testing?
• How do you test forms, donation flows, PDFs, video, menus and third-party integrations?
• Will accessibility be tested throughout development, or only immediately before launch?
• What accessibility documentation do you provide at launch?
• How will you train our staff so that content added after launch remains accessible?
• Can you provide an accessibility remediation plan and ongoing monitoring?

For a disability-focused nonprofit, I'd consider real-user testing with people with disabilities a particularly important differentiator. A site can technically pass automated scans while still being frustrating or unusable for actual visitors.

If you tell me your approximate budget (e.g. <$15k, $15–40k, $40–100k+) and what kind of disability your nonprofit serves, I can narrow this to 3–5 agencies that are the best match and give you their direct contact information and relevant case studies.

Yes. I found several Chicago agencies that look particularly relevant if accessibility for disability-focused or mission-driven nonprofits is a core requirement—not just a generic “ADA-compliant” checkbox.

My shortlist

1. Mightybytes — Best overall fit - Chicago-based and explicitly focused on mission-driven organizations.
2. Accessibility is a major specialty: audits, remediation, training, and manual testing with people who use assistive technologies.
3. They say their deliverables meet WCAG 2.2 AA by default.
4. Particularly interesting for a disability-focused nonprofit because they have worked on accessibility with people using assistive technology rather than relying solely on automated scans. Mightybytes

3. Their team includes accessibility expertise/certification through IAAP.
4. sandstormdesign.com

1. Orbit Media Studios — Strong choice for a larger nonprofit website - Chicago agency with substantial nonprofit experience.
2. A particularly relevant example is their work for Awakenings, a Chicago nonprofit serving survivors of sexual violence; the resulting site is described as mobile-optimized, responsive and accessible. Orbit Media Studios
3. Good option if you need sophisticated content strategy, SEO, integrations and ongoing optimization in addition to accessibility.
4. orbitmedia.com

1. Promet Source — Best for complex/technical nonprofit sites - Chicago-headquartered Drupal/WordPress specialist.

2. Offers web design/development plus accessibility auditing, UX, WordPress, SEO and integrations.

One agency I'd investigate even if location isn't strictly Chicago

Elevation is especially compelling for a disability-focused nonprofit. They're a nonprofit-only web agency and say every site they build meets WCAG 2.2 AA by default, with accessibility audits, manual/assistive-technology testing, remediation, monitoring and staff training. Their team includes CPACC-certified accessibility professionals. Elevation Elevation

elevationweb.org

If I were choosing who to contact first

I'd start with Mightybytes, Sandstorm, Orbit, and Promet Source. For your particular use case, I'd put Mightybytes at #1 because their accessibility practice goes beyond compliance and specifically mentions testing with people who use assistive technologies.

When you contact them, I'd ask for 2–3 examples of sites they've built for organizations serving people with disabilities, and specifically ask:

• Did disabled users participate in usability/accessibility testing?
• What WCAG version and conformance level do you contractually target?
• Do you perform manual keyboard and screen-reader testing, or only automated scans?
• Who actually performs the accessibility testing?
• How do you handle PDFs, forms, video, maps, third-party donation systems and other embedded content?
• Will accessibility be maintained after launch, including training for our staff?
• Can you provide references from nonprofit clients with significant accessibility requirements?

One caution: “ADA compliant” or “WCAG compliant” in an agency's marketing isn't by itself evidence that the resulting site will be genuinely usable by disabled people. For a disability-focused nonprofit, I'd give substantial weight to agencies that can demonstrate participatory testing with disabled users and assistive technology, not just automated accessibility scores.

Yes. I found several Chicago agencies with documented experience in both nonprofit work and accessibility, and a few stand out particularly strongly for a disability-focused organization.

My strongest shortlist

1. Mightybytes — Best overall fit
   • Chicago-based, mission-driven digital agency.
   • Accessibility is a stated baseline: its deliverables are WCAG 2.2 Level AA by default.
   • Offers accessibility audits, remediation, training, and manual testing with people who use assistive technologies.
   • Particularly attractive if you want an agency that treats accessibility as part of the design/development process rather than a final compliance check. www.mightybytes.com
   • Mightybytes website

2. Orbit Media — Best documented disability-nonprofit case study
   • Their Chicago team redesigned the website for Equip for Equality, an Illinois nonprofit whose mission specifically centers on the civil and human rights of people with disabilities.
   • The project explicitly targeted WCAG 2.1 AA, with accessibility reviews incorporated into design and development. www.mightybytes.comwww.orbitmedia.comwindycitywebsolutions.com
   • They also have substantial nonprofit experience beyond disability organizations. www.orbitmedia.com
   • Orbit Media

3. Briteweb — Especially strong disability-sector experience
   • Briteweb redesigned the website for The Chicago Lighthouse, which serves people who are blind, visually impaired, and people with disabilities.
   • This is unusually relevant experience: Briteweb worked with Lighthouse's own accessibility testers, including people using screen readers, screen magnifiers and speech-to-text technology.
   • The resulting site targeted WCAG Level AAA, beyond the usual AA target. rgd.ca
   • Briteweb

4. LimeRed Studio, Inc. — Good mission-driven/Chicago option
   • Chicago agency focused on purpose-driven organizations.
   • Services include web design/development, UX, information architecture, accessibility auditing, WordPress development, and related strategy.
   • Worth contacting if you want a smaller, design/strategy-oriented agency rather than a large digital shop.

5. Sandstorm Design — Strong UX + accessibility combination
   • Chicago-based agency working with mission-led organizations.
   • Their accessibility work includes audits, remediation and training, and they have accessibility expertise through IAAP certification.
   • A good candidate if the project involves complicated information architecture or a large content-heavy nonprofit site.

6. Promet Source — Good for complex Drupal/WordPress sites
   • Chicago-headquartered and experienced with nonprofits, government and other organizations where accessibility, security and governance matter.
   • Particularly worth considering if you need Drupal, a sophisticated resource library, integrations, or a site with complicated content permissions/workflows.

Also worth contacting

• Firebelly Design — Chicago agency with nonprofit experience, accessibility compliance, UX and web development; it also has a long-running program donating design services to nonprofits.
• Windy City Web Solutions — smaller Chicago shop specifically offering nonprofit WordPress development and accessible design. Its nonprofit offering explicitly mentions screen-reader-friendly sites and accessible donation/volunteer tools. windycitywebsolutions.com
• Ensemble Media — particularly relevant if you want a nonprofit/mission-focused communications agency that also handles web work and 508/ADA accessibility.
• Advocate Creative — Chicago agency focused heavily on nonprofits and foundations, with accessibility considerations in its web work.
• West Town Websites — smaller local option emphasizing WCAG/ADA-oriented implementation, including keyboard navigation, screen-reader compatibility, contrast and semantic HTML.

One non-Chicago agency I'd seriously consider

Capellic is worth putting on your list even though it isn't a Chicago agency. It recently built the national Easterseals website and affiliate platform, explicitly targeting WCAG 2.2 AA. That's probably one of the closest matches to your requirement for demonstrated experience with a major disability-focused nonprofit. capellic.com

Capellic

If I were narrowing it to 4

I'd contact Mightybytes, Orbit Media, Briteweb, and Capellic first.

They give you four somewhat different approaches:

One thing I'd specifically ask every agency during the initial call: “Can you describe how people with disabilities participate in your accessibility testing, rather than relying solely on automated WCAG scanners?” That's a much better discriminator than simply asking whether they are “ADA compliant.”

Yes. I found several Chicago-area agencies with both nonprofit experience and demonstrated accessibility expertise. If your organization is disability-focused, I’d prioritize agencies that can show actual work for disability organizations—not just agencies that say they make “ADA-compliant” websites.

My strongest recommendations

1. Mightybytes — Chicago

Best overall fit. Mightybytes is a Chicago-based, mission-driven digital agency, and its accessibility work is unusually relevant to disability nonprofits. It says WCAG 2.2 AA is the default for its deliverables and offers accessibility audits, remediation, training, and manual testing. www.mightybytes.com

Most importantly, Mightybytes has worked with Access Living, a Chicago disability-rights organization, and Disability & Philanthropy Forum. It also partners with Access Living for manual accessibility testing involving people with disabilities. www.mightybytes.com

Contact Mightybytes

2. LimeRed Studio, Inc. — Chicago

A good option if you want a purpose-driven agency with strong UX/branding capabilities. Its services include web design/development, accessibility and SEO auditing, WordPress, and integrations.

Contact LimeRed Studio

3. Sandstorm Design — Chicago

Worth contacting for a larger or more sophisticated redesign. Sandstorm focuses on UX and inclusive design and has accessibility expertise including audits, remediation, and training.

Contact Sandstorm Design

4. Project6 Design

Especially strong disability-specific track record. Project6 built a website for Disability Rights Advocates, a nonprofit legal center serving people with disabilities. That site was designed to be fully accessible and Section 508 compliant. www.project6.com

Project6 currently says it builds nonprofit websites to WCAG 2.2 AA and performs manual screen-reader and keyboard testing, as well as accessibility remediation and monitoring. www.mightybytes.comwww.project6.com

One caveat: Project6 is Bay Area-based rather than Chicago-based, so I'd put it on the list if you're open to a remote agency.

Contact Project6 Design

5. Windy City Web Solutions — Chicago

Potentially better for a smaller nonprofit budget. They specifically build WordPress sites for Chicago nonprofits and have a documented project for Nourishing Hope that emphasized accessibility. Their site says accessibility is incorporated into their WordPress work and that they work directly with the developer rather than routing clients through layers of account management. windycitywebsolutions.com

Contact Windy City Web Solutions

6. Elevation

This is another particularly compelling nonprofit specialist, although it isn't Chicago-based. Elevation says every nonprofit site it builds meets WCAG 2.2 AA by default, and it offers accessibility audits, remediation, monitoring, and staff training. It also explicitly discusses disability and accessibility as part of its agency philosophy. www.elevationweb.org

Contact Elevation

If I were narrowing it to three

For a Chicago disability-focused nonprofit, I'd start with:

I'd put Mightybytes first because the combination of Chicago location, mission-driven work, Access Living relationship, and accessibility testing with people with disabilities is unusually close to what you're looking for. www.mightybytes.com

One important thing to ask in your first conversation

Don't just ask, “Do you build ADA-compliant websites?” Ask:

“Can you show me 2–3 websites you've built for disability-focused nonprofits, and explain how people with disabilities were involved in accessibility testing?”

I'd also ask whether they provide manual keyboard and screen-reader testing, whether accessibility is tested throughout development rather than only at launch, and whether they provide content-editor training after launch. Those questions distinguish a genuine accessibility practice from an agency that simply installs an accessibility widget.

If you tell me your approximate budget (e.g. <$15k, $15–40k, $40k+) and whether you need WordPress, I can narrow this to the 5 best-fit agencies and find the right contact person/email for each.

Yes. I’d prioritize agencies that have both nonprofit experience and demonstrated accessibility work—and I’d distinguish those from firms that merely advertise “ADA compliance.”

My strongest Chicago-area picks

1. Orbit Media Studios — strongest match
   • They have an unusually relevant case study: they redesigned the website for Equip for Equality, an Illinois nonprofit specifically advancing the civil and human rights of people with disabilities.
   • That project explicitly targeted WCAG 2.1 AA, accessibility reviews, better resource navigation, and serving people with disabilities. www.orbitmedia.com
   • Orbit also says it can address WCAG/Section 508 and offers testing with actual users, including people with visual and mobility impairments. www.orbitmedia.com
   • They have substantial nonprofit experience beyond disability organizations. www.orbitmedia.com
   • Contact: Orbit Media contact / discovery call — 773-348-4581.

2. Mightybytes — strongest accessibility-first option
   • Chicago-based, mission-driven digital agency with extensive experience working with purpose-driven organizations.
   • Their stated baseline is WCAG 2.2 Level AA for all deliverables, rather than accessibility being an optional add-on. www.mightybytes.com
   • They also emphasize inclusive UX and accessibility training, which is valuable if your nonprofit needs staff to maintain accessibility after launch. www.mightybytes.com
   • Contact: Mightybytes contact page — 773-561-7529.

3. Sandstorm Design — particularly good for nonprofits
   • Chicago agency with a dedicated nonprofit practice.
   • They specifically say their nonprofit redesigns involve IAAP-certified (CPACC) product owners, designers and engineers, accessibility from the beginning, staff training, and ongoing accessibility audits. www.sandstormdesign.com
   • Their nonprofit portfolio includes organizations such as the Vasculitis Foundation and MPN Research Foundation, so they're accustomed to mission-driven organizations serving people with health-related needs. www.sandstormdesign.com
   • I'd ask them specifically for examples involving disability communities and users of assistive technology.

4. LimeRed Studio, Inc. — good mission-driven/design option
   • Chicago-based agency focused on purpose-driven organizations.
   • Their services include UX/UI, WordPress development, accessibility auditing, SEO, information architecture, and content strategy.
   • This could be a particularly good fit if the project involves brand/storytelling + website redesign, rather than just technical remediation.

5. Firebelly Design — good nonprofit/social-impact design option
   • Chicago agency with a long-standing social-impact orientation and extensive nonprofit work.
   • Their digital practice explicitly includes accessibility compliance, information architecture, UX strategy and responsive development. firebellydesign.com
   • They also have a history of donating design services to nonprofits through their Grant for Good program.
   • Contact: Firebelly contact page — 773-489-3200.

One more I'd consider

Ensemble Media is worth contacting if your organization needs a combination of nonprofit communications, web design, and accessibility. They're a Chicago-based, woman-owned firm focused heavily on nonprofits, foundations and social-impact organizations, and their work references ADA/Section 508 accessibility.

My shortlist

If this were my RFP, I'd start with:

Orbit is the clear first call because there's direct evidence of building a site for an Illinois disability-rights nonprofit, rather than simply claiming accessibility expertise. www.orbitmedia.com

When you contact them, I'd ask one important question: “Can you describe how people with disabilities and assistive-technology users will participate in accessibility testing—not just which automated WCAG checker you'll use?” That will help separate genuine accessibility expertise from agencies that primarily rely on automated scans or accessibility overlays.

If you tell me your approximate budget and whether this is a redesign or a new site, I can narrow this to 3 agencies and compare likely fit, nonprofit experience, accessibility approach, and contact information.

Yes. I found several Chicago-area agencies that look particularly relevant. I’d prioritize agencies with documented nonprofit experience plus demonstrated accessibility work, rather than agencies that merely advertise “ADA compliance.”

Strongest matches

1. Mightybytes — probably my first call

Chicago-based, mission-driven digital agency with substantial nonprofit/purpose-driven experience. They say WCAG 2.2 AA is their default for deliverables and offer accessibility audits, remediation, training, and manual testing with people who use assistive technologies. www.mightybytes.com
Mightybytes website

2. Clique Studios

Chicago agency with nonprofit experience and explicit services around UX, usability testing, accessibility design, and web development. This could be a good fit for a larger redesign or a site with complicated integrations.
Clique Studios website

3. Sandstorm Design

Chicago-based agency focused on UX, inclusive design, and digital experiences for mission-driven organizations. Worth considering if you want accessibility integrated into research, content strategy, UX, and development rather than treated as a compliance step at the end.

4. LimeRed Studio, Inc.

Particularly interesting for nonprofits: they work with purpose-driven organizations and offer web design/development, accessibility auditing, UX, WordPress, integrations, and content strategy. www.project6.com

5. Promet Source

A strong option if your nonprofit has a large content/resource library, complicated information architecture, Drupal needs, or accessibility/governance requirements. Their Chicago practice works with nonprofits and other mission-driven organizations.

6. Dialogue Theory

Smaller Chicago digital design/development studio working with nonprofits and civic/public-interest organizations. Their positioning specifically emphasizes accessibility and inclusive design, which could make them a good fit if you want a more hands-on partner.

7. Windy City Web Solutions

A smaller, potentially more budget-friendly Chicago option. They specifically market WordPress services to nonprofits and say accessibility is incorporated into their builds. windycitywebsolutions.com

One especially compelling case study

Orbit Media Studios deserves special attention because I found unusually strong evidence directly matching your description. Orbit built the new website for Equip for Equality, an Illinois nonprofit whose mission is advancing the civil and human rights of people with disabilities. The project specifically targeted WCAG 2.1 AA, accessibility reviews, improved resource organization, and easier access to advocacy/resources. www.orbitmedia.com

Orbit Media's Equip for Equality case study

That is considerably stronger evidence than an agency simply saying “we build ADA-compliant websites.”

Also worth knowing

If your organization is disability-focused, I'd consider involving The Chicago Lighthouse even if you don't use them as the web-development agency. Their Digital Accessible Experience (DAX) team provides accessibility consulting, audits, WCAG/Section 508 work, training, and technology assistance, with experience involving people who are blind or visually impaired. chicagolighthouse.org

The Chicago Lighthouse accessibility services

A particularly strong setup would be web agency + independent accessibility/user testing, so the agency isn't the only party evaluating whether its own work is accessible.

My shortlist

If I were sending RFPs, I'd start with:

When you contact them, I'd ask three questions that will quickly separate genuine accessibility expertise from marketing claims:

• “Can you show me 2–3 nonprofit websites you've built that were designed to WCAG 2.2 AA?”
• “Do you conduct manual testing with screen readers and keyboard-only users, or primarily automated accessibility scans?”
• “Have you worked directly with people with disabilities during research or usability testing?”

The second and third questions are especially important: an accessibility overlay/widget is not a substitute for building an accessible site.

If you tell me your approximate budget (e.g. <$25k, $25–50k, $50–100k+) and whether you need WordPress/Drupal/another CMS, I can narrow this to the 3–5 best agencies and find the right contact person/email or inquiry page for each.

Yes. I’d prioritize agencies that show both nonprofit/mission-driven experience and substantive accessibility expertise, rather than agencies that merely advertise “ADA compliance.”

Strongest Chicago options

1. Mightybytes — my first call
   • Chicago-based, purpose-driven digital agency with extensive nonprofit/social-impact work.
   • Accessibility is a core service, not an add-on: they say their deliverables comply with WCAG 2.2 AA by default.
   • They have specifically done accessibility-focused work with Access Living, a Chicago disability-rights organization, which is particularly relevant to your request. www.mightybytes.comwww.mightybytes.com
   • Contact: Mightybytes contact form
   • Best fit: a disability-focused nonprofit that wants an agency with genuine accessibility and social-impact experience.

2. Promet Source

   • Their portfolio includes public-service organizations such as health and human-services agencies, which makes them particularly interesting if your nonprofit has complex programs, resource directories, applications, or forms. www.prometsource.com
   • Contact: 773-525-8255, ignite@prometsource.com, or Promet Source contact/RFP page
   • Best fit: a larger/complex nonprofit website, particularly Drupal or WordPress.

   • Chicago-based agency with accessibility, UX, web design/development and nonprofit experience. Pantheon's agency directory specifically lists all four as their services/industries. directory.pantheon.io
   • Their accessibility work includes audits, remediation and training, and the agency has accessibility certification experience.
   • Best fit: an organization looking for a polished brand/UX experience alongside serious accessibility work.

   • More of a small-business/small-nonprofit option. They specifically market Chicago nonprofit web design, WordPress, accessibility and ongoing maintenance. windycitywebsolutions.com
   • Best fit: a smaller organization with a modest budget that doesn't need a large agency.

One particularly interesting specialist

Dialogue Theory is worth contacting if you want a more boutique, UX-oriented partner. They're a Chicago digital design/development studio focused on mission-driven organizations and nonprofits, with accessibility and inclusive design explicitly part of their work.

How I'd narrow it down

For a disability-focused nonprofit, I'd contact these three first:

One reason I'm putting Mightybytes first is that working with Access Living is much stronger evidence of relevant disability-community experience than simply claiming WCAG expertise. Their current materials also say WCAG 2.2 AA is their default standard. www.mightybytes.comdirectory.pantheon.iowww.mightybytes.com

What I'd ask each agency

When you contact them, I'd ask specifically:

• “Can you show me 2–3 nonprofit websites you've built or substantially redesigned that serve people with disabilities?”
• “Was accessibility tested by people who actually use screen readers, keyboard navigation, or other assistive technology, rather than only automated scanners?”
• “Do you build to WCAG 2.2 AA, and will that be an explicit requirement in the contract?”
• “Will accessibility cover forms, donation systems, PDFs, event registration, video, maps and third-party embeds, or just the core pages?”
• “Will you provide accessibility testing/remediation after launch?”
• “Can you provide references from a nonprofit whose primary audience includes people with disabilities?”

That last point is important: an agency can technically know WCAG without really understanding the lived experience of the people your organization serves.

If you tell me your approximate website budget (e.g. <$15k, $15–40k, $40k+) and whether this is a new site or redesign, I can narrow this to 3–5 agencies and compare their likely fit, accessibility credentials, nonprofit portfolio, and contact information.

Yes. I found several Chicago-area agencies with credible evidence of both nonprofit/mission-driven work and accessibility expertise. For a disability-focused nonprofit, I’d prioritize the ones below rather than agencies that merely advertise “ADA-compliant websites.”

Strongest matches

1. Orbit Media Studios — Best direct Chicago match
   • They built the website for Equip for Equality, an Illinois nonprofit whose mission is specifically advancing the rights of people with disabilities.
   • The project targeted WCAG 2.1 Level AA, including accessibility reviews, improved information architecture, and a redesigned resource library. www.orbitmedia.com
   • Chicago office: 4043 N Ravenswood Ave.
   • Orbit Media's Equip for Equality case study

2. Mightybytes — Excellent accessibility + mission-driven fit
   • Chicago-based and focused heavily on purpose-driven organizations.
   • They say their deliverables comply with WCAG 2.2 Level AA by default, and they offer accessibility audits, remediation and training. www.mightybytes.com
   • Their approach also emphasizes inclusive design and testing rather than simply installing an accessibility overlay.
   • Mightybytes

3. Sandstorm Design — Worth contacting for a sophisticated nonprofit redesign
   • Chicago-based, with a strong focus on UX, inclusive design and mission-driven organizations.
   • Their accessibility practice includes audits, remediation and training, and they have accessibility expertise through IAAP certification.
   • Particularly interesting if your organization needs strategy + UX + accessibility, rather than just development.

4. Promet Source — Good for complex organizations
   • Chicago-based Drupal/WordPress agency with experience in nonprofits, higher education and public-sector organizations.
   • Their work emphasizes accessibility, governance and repeatable compliance practices.
   • A good candidate if you have a large content library, complicated integrations, or many people managing the site.

5. Dialogue Theory — Good mission-driven/UX option
   • Chicago studio working with nonprofits and civic/public-interest organizations.
   • Their local-business profile specifically highlights accessibility and inclusive design as part of their work.
   • I'd ask for disability-sector references before putting them ahead of Orbit or Mightybytes.

One particularly interesting non-Chicago option

Briteweb deserves a look even though it's not Chicago-based. They redesigned The Chicago Lighthouse's website specifically around accessibility and worked with the Lighthouse's own Digital Accessible Experience team, including blind and visually impaired testers using screen readers, magnification and speech-to-text technology. The resulting site achieved WCAG Level AAA. rgd.ca

That's unusually relevant experience for a disability-focused organization.

My shortlist

If I were sending out an RFP, I'd start with:

One other agency caught my attention: Capellic recently rebuilt the national Easterseals website and platform, with accessibility as a core requirement and WCAG 2.2 AA as the target. capellic.com If you're willing to consider agencies outside Chicago, I'd put them on the RFP list too.

When you contact these agencies, I'd ask one question that will separate genuine accessibility expertise from marketing claims:

“Can you give us two references from disability-serving organizations, and explain how people with disabilities participated in accessibility testing during the design and development process?”

That will tell you much more than whether an agency says “ADA compliant” on its website.

Yes. I found a few Chicago agencies that stand out specifically for accessibility + nonprofit/mission-driven work, rather than just claiming generic ADA/WCAG expertise.

Best matches

1. Mightybytes — strongest match
   • Chicago-based, mission-driven digital agency.
   • Explicitly builds to WCAG 2.2 AA by default.
   • Their accessibility portfolio specifically includes Access Living, Able Play, and the Disability & Philanthropy Forum.
   • The Disability & Philanthropy Forum testimonial specifically describes Mightybytes helping create an accessible website. www.mightybytes.comwww.mightybytes.com
   • They offer audits, remediation, accessible UX/design, testing and staff training—not just a one-time accessibility check. www.mightybytes.comwww.orbitmedia.comwww.prometsource.comosd.umn.edu
   • Contact: 773-561-7529; their site offers a strategy-call/contact route. www.mightybytes.comwww.mightybytes.com
   • Mightybytes website

2. Orbit Media Studios — strongest nonprofit web-design option
   • Chicago agency with a substantial nonprofit portfolio and dedicated nonprofit web-design practice.
   • Explicit accessibility work includes WCAG/Section 508, accessible UX/UI, keyboard navigation, screen-reader compatibility, and testing with actual users. www.orbitmedia.com
   • Their nonprofit portfolio includes organizations such as the Greater Chicago Food Depository, Erika's Lighthouse, Illinois Action for Children and others. www.orbitmedia.com
   • I didn't find public evidence as strong as Mightybytes' disability-specific client list, so I'd ask them specifically for 2–3 examples involving disability-serving organizations.
   • Contact: 773-348-4581; they offer a discovery-call form. www.orbitmedia.com
   • Orbit Media Studios website

3. Promet Source — particularly good for complex/accessibility-heavy sites
   • Chicago-based Drupal/WordPress agency with a strong accessibility practice.
   • Specializes in accessible sites for mission-driven organizations, nonprofits, government and higher education.

   • Promet Source website

4. Sandstorm Design — worth an RFP
   • Chicago UX/digital agency with 20+ years of nonprofit experience.
   • Their team includes IAAP CPACC accessibility-certified professionals and they have an iterative accessibility audit/validation process plus accessibility training for content administrators. osd.umn.edu
   • Particularly interesting if your project involves substantial UX research and user testing, rather than simply replacing an existing site.
   • Contact: 773-348-4200. osd.umn.edu
   • Sandstorm Design website

My shortlist

If I were selecting three agencies to contact first, I'd go:

1. Mightybytes → best demonstrated disability-sector experience
2. Orbit Media → strongest combination of Chicago nonprofit experience + web design/development
3. Promet Source → strongest technical accessibility/compliance option

For a disability-focused nonprofit, I'd make one question a requirement in your initial outreach:

“Can you show us 2–3 websites you've built for disability organizations or organizations serving people with disabilities, and explain how people with disabilities participated in the research, design, testing, or accessibility validation?”

That question should separate genuine accessibility expertise from agencies that simply run automated WCAG scans.

If you tell me your approximate budget (e.g. <$25k, $25–75k, $75k+) and whether you need WordPress/Drupal, I can narrow this to the best 3–5 agencies and find the right contact person/RFP page for each.

Yes. I found several Chicago agencies with credible evidence of both accessibility expertise and nonprofit/mission-driven work. For a disability-focused nonprofit, I’d prioritize the first four.

Best matches

1. Mightybytes — strongest overall fit
   • Chicago-based, mission-driven digital agency.
   • Accessibility is built into its process rather than treated as an add-on; it says its deliverables comply with WCAG 2.2 Level AA by default.
   • Provides accessibility audits, remediation, training, and manual testing involving people who use assistive technologies.
   • Has worked with hundreds of purpose-driven organizations. www.mightybytes.com
   • Contact: (773) 561-7529; 1725 W Balmoral Ave., Chicago. www.mightybytes.com
   • Mightybytes website

2. Orbit Media Studios — excellent nonprofit + accessibility combination
   • Chicago agency with extensive nonprofit experience, including the Greater Chicago Food Depository, Nourishing Hope, SitStayRead and others.
   • Explicitly offers WCAG/ADA accessibility services, accessibility audits, accessible UX/UI, and testing with actual users.
   • Their SitStayRead project specifically addressed accessibility risks, readability, usability and accessible design. www.orbitmedia.com
   • Contact: (773) 348-4581; 4043 N Ravenswood Ave., Suite 316, Chicago. www.orbitmedia.com
   • Orbit Media website

3. Promet Source — particularly worth considering for a complex nonprofit site
   • Chicago-headquartered web development agency with a strong focus on Drupal/WordPress, accessibility, Section 508, WCAG and ADA requirements.
   • Its client base includes nonprofits, higher education and public-sector organizations where accessibility and governance are important.
   • This could be especially good if your organization has lots of resources, programs, forms, directories or complicated content architecture.

4. Sandstorm Design — strong UX/inclusive-design option
   • Chicago-based, women-led agency focused on UX, inclusive design and digital work for mission-driven organizations.
   • Offers accessibility audits, remediation and training, and has accessibility expertise/certification.
   • Worth contacting if you want accessibility deeply integrated into the research → UX → design → development process.

One especially relevant non-Chicago option

Capellic deserves a look even though it's not Chicago-based. They recently redesigned the national Easterseals website—the organization is explicitly disability-focused—and built accessibility into the process, targeting WCAG 2.2 AA. Their case study reports an accessibility-score improvement after the redesign. capellic.com

That makes them unusually relevant if your priority is “show me you've actually built for a disability organization,” rather than simply “you offer ADA compliance.”

My shortlist

If this were my RFP, I'd contact Mightybytes, Orbit, Promet Source, and Capellic first. The key question I'd ask each isn't merely “Are you ADA compliant?” but “Can you show us a disability-focused project, explain how people with disabilities participated in research/testing, and describe how you validate WCAG conformance before and after launch?”

That distinction can help you avoid agencies whose “accessibility” offering is mostly an automated overlay rather than genuinely accessible UX and code.

For a disability-focused nonprofit, I’d prioritize agencies that can show real accessibility practice (WCAG/ADA experience, keyboard and screen-reader testing, inclusive UX research) rather than just saying “ADA compliant.” These Chicago-area agencies are worth contacting:

A few other Chicago agencies with strong general web reputations that I’d screen specifically for disability/nonprofit experience:

• Orbit Media Studios — established Chicago web agency; ask for examples of WCAG-tested nonprofit sites.
• Solid Digital — larger B2B/digital agency; worth asking about accessibility workflows and nonprofit references.

When you contact them, I’d ask:

1. “Can you share 2–3 nonprofit websites you built that were designed for people with disabilities?”
2. “Do you test with screen readers and keyboard-only navigation, or only run automated scans?”
3. “What accessibility standard do you target (WCAG 2.1 AA, WCAG 2.2 AA, Section 508)?”
4. “Will disabled users be involved in usability testing?”
5. “Can you train our staff to maintain accessibility after launch?”

For a disability-focused nonprofit, my first outreach shortlist would probably be Mightybytes, Project6, and Mire & Muse because accessibility appears to be a documented part of their process rather than an add-on. www.mightybytes.com

Yes. I found several Chicago-area agencies with documented nonprofit work plus meaningful accessibility experience. For a disability-focused nonprofit, I’d prioritize agencies that have actually worked with disability-serving organizations rather than agencies that merely advertise “ADA compliance.”

Strongest matches

1. Clique Studios — Chicago

They combine web strategy, UX/UI, development, usability testing, and accessibility design, and list nonprofits among their industries. They look like a good option for a larger, more complex redesign.

2. Mightybytes — Chicago

Particularly compelling if accessibility is a central requirement. Mightybytes says its deliverables meet WCAG 2.2 AA by default and offers accessibility audits, remediation, training, and manual testing with people using assistive technologies. www.mightybytes.com

3. Promet Source — Chicago

A strong candidate for a large nonprofit with complicated content, Drupal/WordPress needs, or substantial accessibility/governance requirements. Its client base includes nonprofits, government, and higher education.

4. LimeRed Studio — Chicago

Purpose-driven organization specialist with nonprofit experience and services including web design/development, accessibility auditing, UX, WordPress, and integrations. This could be a particularly good fit for a mission-driven organization that wants strategy and storytelling alongside development.

5. Sandstorm Design — Chicago

Focuses on UX, inclusive design, accessibility, and enterprise web development, with nonprofit and other mission-driven organizations among its clientele. Worth considering for a substantial redesign.

Especially relevant disability/nonprofit experience

Orbit Media Studios is probably the most compelling example I found. Its published case study for Equip for Equality, an Illinois nonprofit whose mission is advancing the civil and human rights of people with disabilities, specifically describes redesigning the organization's site to achieve WCAG 2.1 Level AA, reorganize its resource library, and improve accessibility. www.orbitmedia.com

Orbit also has multiple other nonprofit accessibility projects, including Awakenings, where it describes the resulting site as responsive and accessible. www.orbitmedia.com

Another noteworthy example is Landslide Creative, which published a nonprofit case study emphasizing WCAG AA accessibility and designing for audiences with different abilities and levels of internet access. landslidecreative.com

And Project6 says it has worked with 36+ foundations/nonprofits and that most of its clients need WCAG 2.2 AA compliance. www.project6.com

One particularly interesting option outside the traditional agency model

Garenne Bigby is a Chicago web designer specializing in information architecture, usability, and accessibility. This could be worth investigating if you're a smaller nonprofit that wants a more hands-on individual practitioner rather than a large agency.

My shortlist

If I were sending RFPs, I'd start with:

One thing I'd specifically ask every agency: “Can you provide references from disability-led or disability-serving organizations, and will people with disabilities/assistive-technology users participate in accessibility testing?” A site can technically pass an automated WCAG scan while still being frustrating or unusable for real people.

If you tell me your approximate budget (e.g. <$25k, $25–75k, $75k+) and whether this is a redesign or new site, I can narrow this to 3–5 agencies that are the best fit and find their direct contact/RFP pages.

Yes. I’d put Mightybytes at the top of your list because I found unusually direct evidence of both Chicago-based work and experience with disability-focused nonprofits.

Best matches

1. Mightybytes — strongest fit
   • Chicago-based, mission-driven digital agency.
   • Built/reworked the website for Access Living, a Chicago disability-rights organization. That project launched at WCAG AAA accessibility, included testing with people using assistive technologies, and addressed needs of people with physical, visual, hearing, and cognitive disabilities. www.mightybytes.com
   • They also work with Disability & Philanthropy Forum and have an ongoing partnership with Access Living for manual accessibility testing by people using assistive technologies. www.mightybytes.com
   • They say WCAG 2.2 AA is their default standard for deliverables. www.mightybytes.com
   • Contact: Mightybytes

2. Promet Source — good for a more technical/complex nonprofit
   • Chicago-headquartered agency specializing in Drupal/WordPress and organizations with substantial accessibility, governance, and content requirements.
   • Particularly worth considering if your nonprofit has a large site, complicated programs/resources, or needs strong CMS accessibility and long-term maintenance.
   • Contact: Promet Source

3. Sandstorm Design — strong UX/inclusive-design option
   • Chicago-based and focused on mission-driven organizations.
   • Their work includes accessibility audits, remediation, and training, with accessibility expertise built into their UX/design approach.
   • I'd ask specifically for examples involving disability-serving organizations, since the evidence I found is stronger for accessibility expertise than for disability-nonprofit specialization.
   • Contact: Sandstorm Design

4. LimeRed Studio, Inc. — good nonprofit/purpose-driven fit
   • Chicago agency working with purpose-driven organizations.
   • Offers web design/development plus accessibility auditing, UX/UI, information architecture, WordPress, and related services.
   • Again, I'd ask them for disability-specific case studies before putting them ahead of Mightybytes.
   • Contact: LimeRed Studio

5. Windy City Web Solutions — potentially better for a smaller nonprofit
   • Chicago-based and specifically markets nonprofit web design.
   • Their nonprofit offering emphasizes accessible, clear WordPress sites and ongoing maintenance. windycitywebsolutions.com
   • I found less evidence of disability-specific nonprofit work than with Mightybytes, so I'd treat this as a budget/size-oriented option rather than the strongest accessibility specialist.
   • Contact: Windy City Web Solutions

One agency I'd consider if "Chicago" can mean Chicago-area

Project6 has perhaps the strongest documented disability-nonprofit accessibility case study after Mightybytes: it built a fully accessible site for Disability Rights Advocates, a nonprofit legal organization serving people with disabilities. It explicitly offers WCAG 2.2 AA testing, accessible UX/UI, semantic HTML/ARIA development, and manual screen-reader/keyboard testing. www.project6.com

However, I wouldn't put it in the Chicago shortlist without confirming its current Chicago availability/location; the evidence I found doesn't establish it as Chicago-based as clearly as the agencies above.

My shortlist for an RFP

If this were my project, I'd contact Mightybytes, Promet Source, Sandstorm, and LimeRed and ask each for:

• 2–3 disability-focused nonprofit examples
• Whether people with disabilities participated in user testing
• Whether they test manually with screen readers, keyboard navigation, and mobile assistive technology
• What conformance level they target (WCAG 2.2 AA is a sensible baseline)
• Who is responsible for accessibility after launch
• Whether accessibility is included in the quoted project price rather than treated as an add-on

Mightybytes is the clear first call based on the evidence I found: their Access Living project is almost exactly the combination you're looking for—Chicago + nonprofit + disability rights + actual accessible-site implementation + testing with disabled users. www.mightybytes.com

If you'd like, I can also find 5–10 more Chicago agencies and rank them by disability-nonprofit experience, accessibility expertise, nonprofit experience, and likely price range, including direct contact links.
