For over 25 years, Marilyn Golden has led national system-change efforts that broaden the rights of people with disabilities to transportation. Marilyn has played a key role in federal policy development in the interconnected areas of transportation and architectural barriers. She has been a strong advocate for the Americans with Disabilities Act (ADA) throughout all the stages of its proposal, passage, and implementation, as well as a forceful watchdog through its many stages of regulatory interpretation and the regular challenges to its strong mandates. Her advocacy has been focused on a broad range of transportation issues—including fixed route buses, all forms of passenger rail systems, ADA complementary paratransit, privately-funded over-the-road buses, taxis, airport shuttles, as well as air travel. As a national transportation advocate, she has led the struggle for many of the policy victories during and since the ADA to provide better public transportation for people with disabilities. Marilyn served on the U.S. Architectural and Transportation Barriers Compliance Board from 1996-2005 as a very strong and effective advocate for the interests of people with disabilities.
