I enjoy drawing on my experience at the highest levels of federal government and in the courts to help solve clients’ pressing challenges. Having navigated the complexities of federal grantmaking, loan programs, environmental review, litigation, and regulation, I help states, transit agencies, real estate developers, construction firms, and others advance their major projects and resolve novel, high-stakes regulatory and litigation matters.

Subash brings a significant depth of legal and public policy experience to the firm. As Acting General Counsel of USDOT, he served as Transportation Secretary Pete Buttigieg’s top legal advisor, overseeing a 500-person legal team, leading the Department’s rulemaking agenda, streamlining processes to expedite project delivery, and defending landmark transportation and environmental policies. As Chief Counsel at the Federal Transit Administration (FTA), Subash worked to implement the historic Infrastructure Investment and Jobs Act and oversaw all FTA legal matters, including on Buy America compliance and safety and labor regulations. Prior to joining USDOT, Subash served as Special Counsel for Ethics, Risk, and Compliance at the Metropolitan Transportation Authority (MTA) in New York. Subash also brings a strong litigation background from private practice in Washington, D.C., where he helped deliver multiple Supreme Court and court of appeals victories for his clients.

Subash began his legal career with three prestigious clerkships – serving at the U.S. District Court for the Southern District of New York, the U.S. Court of Appeals for the Second Circuit, and the U.S. Supreme Court for Justice Ruth Bader Ginsburg.
