Thomas is an accomplished advocate, counselor, and problem-solver. With more than 20 years of experience in complex civil and appellate litigation, he has presented numerous oral arguments in federal and state appellate courts, including the U.S. Court of Appeals for the Fifth Circuit and the Texas Supreme Court. Thomas works closely with trial attorneys and formulates strategies at all stages of litigation. He also counsels clients in non-litigation contexts, such as corporate transactions and compliance, to assess legal risk and mitigate potential exposure.

Thomas brings a creative, forward-looking approach to his practice, and has achieved groundbreaking results. Before joining Frost Brown Todd, he successfully argued in the Fifth Circuit on behalf of a healthcare provider challenging the federal government’s recoupment of Medicare payments—resulting in the bellwether opinion of Family Rehabilitation v. Azar. Thomas played a principal role in achieving a unanimous Texas Supreme Court victory for a group of indigent litigants in Campbell v. Wilder, a high-profile access-to-justice case. And he successfully argued in the Texas Supreme Court for a commercial tenant in Italian Cowboy Partners v. Prudential Insurance Co., which clarified an important area of Texas contract law.

Thomas is committed to pro bono and community service. In 2017, he was a recipient of the “Impact Award” by the Poverty Law Section of the State Bar of Texas. Thomas also serves on the Board of Directors for the Dallas Zoo.
