National Experience. Custom Solutions.

ADA One is a consulting firm drawing on the three decades of disability rights experience of Irene Bowen, J.D.

It offers one source for learning about and complying with the Americans with Disabilities Act (ADA) and related laws.

NOTE: The firm is not accepting new clients and plans to finish current projects by the end of 2022. Our current focus is on developing “Corada Pro,” an ADA self-evaluation and compliance app, with Evan Terry Associates.


Founder, Irene Bowen

head shot.Jan2013 AADA One consulting grows from President Irene Bowen’s thirty years of experience – and results – as Deputy Chief of the Disability Rights Section at the U.S. Department of Justice and as Deputy General Counsel of the U.S. Access Board. She achieved ADA compliance through landmark litigation, settlements, and education.

Ms. Bowen doesn’t just know, study, and apply the laws and regulations – she wrote and enforced many of their provisions. She understands what’s behind them. She grasps what the federal government expects for compliance, how it operates, and what it may do next.
