Marc Dubin, Esq.
Founder, ADA Expertise Consulting, LLC
Marc graduated from law school in 1981, and entered the Justice Department's Honors Program. He then served as a prosecutor for a decade, and then returned to the Justice Department in 1992, the year the ADA took effect. Marc was one of the first attorneys hired by the Justice Department to enforce the ADA, andwas responsible for many of the Justice Department’s major investigations and cases. He has expertise in all aspects of the ADA and Section 504, and is a widely sought after trainer and speaker. He learned the ADA by helping the federal government enforce the ADA. He also testifies as an expert in the ADA in federal court nationwide.
Our goal is to help businesses and state and local governments achieve compliance through education, and to help our clients avoid litigation and federal investigations. In the event you are engaged in litigation, we can help.
We provide expert guidance in the ADA and Section 504, to assist our clients, their attorneys, and their architects. We also assist state and local governments with litigation and development and updates of Self-Evaluation Plans and Transition Plans under title II of the ADA, and train ADA Coordinators so that they can better understand and comply with the law.
In addition, we provide businesses with an understanding of their obligations, and collaborate with other experts. We provide assessments of websites and video broadcasts to help them be accessible to visitors with disabilities, including assessing whether the website is coded correctly to make it accessible, and to assess whether the PDFs on the website are accessible.
We also provide training and support to building code officials and business owners, to help them better understand the application of the ADA to the businesses they regulate. The ADA is a federal civil rights law, not a building code, and many businesses find, too late, that receiving a local building permit does not mean that they are in compliance with the ADA. We can help.
