Who We Are

Ann Landis was flying home from a conference. At 30,000 feet, free from ordinary distractions, she couldn’t stop thinking about her design team.

Her company was steadily winning web projects. She understood what her clients needed and had spent hours writing thoughtful creative briefs. The designers had spent hours trying to interpret them. Everyone was intelligent. Everyone cared about doing great work. Yet somehow, they kept talking past one another.

At first, it seemed like a communication problem. But in that moment, Ann realized it was something much deeper.

No two people process information in exactly the same way.

Some think visually. Others think in words. Some navigate with a mouse, others with a keyboard or screen reader. Some need structure. Others need flexibility. Every day, digital systems make assumptions about the people using them—and too often, those assumptions become barriers.

That realization is the heart of Tamarin Software.

We believe the best organizations build Humane Digital Systems—digital experiences that reduce friction, expand participation, and adapt to the ways real people of all abilities interact with information.

We call it Accessibility for All.

Accessibility for All isn’t a checklist. It’s a methodology for creating websites, documents, content, and digital services that respect the diversity of human experience. It means designing technology that works across devices, abilities, learning styles, and ways of interacting with information. It means building systems that are easier to understand, easier to maintain, and resilient enough to evolve as organizations grow.

Whether we’re improving a website, developing accessible documents, training content teams, advising designers and developers, or helping organizations prepare for ADA Title II and WCAG requirements, our mission remains the same:

Build Humane Digital Systems. Create Accessibility for All.

Because technology should adapt to people—not the other way around.

She helps designers, developers, and content teams build Humane Digital Systems that reduce friction, expand participation, and create Accessibility for All.

Ann believes technology should adapt to people—not the other way around. That belief shapes every aspect of her work, from accessible websites and documents to digital strategy, content systems, and organizational processes. Rather than treating accessibility as a final review or compliance exercise, she helps organizations weave it into the way they design, build, communicate, and grow.

Her work spans ADA Title II readiness, WCAG conformance, accessible document design, accessibility strategy, training, implementation support, and digital process improvement. Drawing on a background in software development, communications, web strategy, information design, and process improvement, Ann helps organizations build systems that are easier to understand, easier to maintain, and more effective for everyone.

Known for bridging the gap between disciplines, Ann translates complex technical and accessibility requirements into practical solutions that designers can design, developers can build, content teams can maintain, and leaders can confidently support. Her work helps organizations move beyond compliance to create digital experiences that are resilient, sustainable, and centered on the people they serve.

Ann has worked with organizations including Booz Allen Hamilton, Johns Hopkins University, the Children’s Hospital of Philadelphia, and the Maryland Department of Transportation. She is the author of Selling with Stories: How to Attract Your Ideal Client with Words and Pictures, a former “Top Three” winner in the George Washington University Global Case Study Competition, and a former Innovation Fellow in Montgomery County, Maryland.

Outside of her consulting work, Ann writes fiction, keeps honey bees, and remains endlessly fascinated by healthy systems—digital, natural, and ecological. Whether she’s designing technology or tending a beehive, she believes the healthiest systems don’t demand that people adapt to them. They adapt to the people they serve.
