Deepak Gupta is founder of Gupta Wessler LLP, where he represents plaintiffs in high-stakes appeals nationwide. Trial lawyers across the country enlist him to defend their most significant victories, or revive worthy claims—including some of the nation’s largest jury verdicts.
Over more than two decades, Deepak has led appeals before the U.S. Supreme Court, all thirteen federal circuits, and numerous state appellate and supreme courts, with a focus on ensuring access to justice for consumers, workers, investors, and communities injured by corporate or governmental misconduct. He has also testified before the U.S. Senate, the U.S. House of Representatives, and the Presidential Commission on the Supreme Court. Deepak is a lecturer at Harvard Law School, where he teaches the Harvard Supreme Court Litigation Clinic.
In 2025, the National Law Journal observed that Deepak “has steadily become a mainstay of the Supreme Court lectern and the go-to advocate for consumers and other plaintiffs with cases before the justices.” Over the past two terms alone, the firm had seven oral arguments before the U.S. Supreme Court, presented by all four of the firm’s principals. Only four other law firms–all large corporate defense firms–had as many arguments. Gupta Wessler had the highest win rate (71%) of any firm in that elite group. All told, the firm’s lawyers have argued more than thirty Supreme Court cases.
Deepak has been described as “a skilled appellate lawyer” (New York Times), “an all star Supreme Court litigator” (Washington Post), “one of the emerging giants of the appellate and Supreme Court bar,” (Law360) and a “legal rock star” (New York Law Journal). Chambers USA praises his “impressive” and “highly rated appellate practice,” calling him “an incredible oral advocate” who “writes terrific briefs.”
