Matt Wessler

Matt Wessler is a principal at Gupta Wessler PLLC, where he focuses on public interest and plaintiffs’-side appellate and complex litigation.
Matt handles high-profile cases at all levels of both state and federal court and has argued multiple cases before the U.S. Supreme Court, including US Airways v. McCutchen—a landmark ERISA case. Outside of the Supreme Court, Matt’s practice involves a wide range of areas including class actions, health care, employee benefits, consumer protection, preemption, arbitration, and banking. He was named a 2015 Washington DC Rising Star in appellate litigation and has been profiled by the National Law Journal for his appellate work on behalf of plaintiffs. In addition to his appellate work, Matt frequently co-counsels with trial firms in complex, ground-up litigation.
Before joining the firm in July 2015, Matt spent six years as a staff attorney at Public Justice, P.C. in Washington, DC, where he spearheaded the firm’s focus on Supreme Court litigation and garnered national attention for taking the lead in high-profile cases involving ERISA, preemption, arbitration, and health care.
Matt previously practiced at the Washington law firm of Williams & Connolly LLP and was a member of Obama for America’s sensitive litigation team, where he handled important election litigation on behalf of the presidential campaign. He clerked for the Honorable Richard L. Nygaard of the U.S Court of Appeals for the Third Circuit and the Honorable William E. Smith of the U.S. District Court for the District of Rhode Island. Matt is a graduate of Cornell Law School and Williams College.
Matt routinely speaks in front of audiences across the country, and to the media, on issues affecting plaintiffs’ litigation and public interest law. His cases have been profiled in major media outlets, including the New York Times, Washington Post, Reuters, Bloomberg News, and Mother Jones. He splits his time between Cambridge, Massachusetts and Washington, DC and, when he can, the mountains.
