Steven L. Groopman is a seasoned class action attorney and a partner in DiCello Levitt’s Antitrust and Competition Litigation Practice Group. He focuses primarily on high-stakes antitrust matters—with particular expertise in the health care sector—bringing a strategic, deeply researched approach to cases involving complex markets, sophisticated corporate conduct, and significant economic harm. He also has experience in consumer fintech litigation.
Steve is known for developing cutting-edge, proprietary cases—often before the issues receive mainstream coverage—through deep investigation and analysis. He has significant experience litigating on behalf of union health and welfare benefit funds, individual consumers, and small independent businesses against large corporate defendants. His health care antitrust practice has successfully challenged tactics used to delay, deter, and undermine generic and biosimilar competition, and other conduct affecting competition and pricing in pharmaceutical and health care markets. He also has developed and litigated antitrust claims in other sectors, including real estate and airlines.
Before joining DiCello Levitt, Steve was a partner in the Boston office of an esteemed class action and complex litigation firm. Earlier in his career, he clerked for the Hon. Dickinson R. Debevoise of the U.S. District Court for the District of New Jersey and practiced at a litigation and white-collar defense boutique in New York. During law school, Steve interned at the World Organization for Human Rights and for the Hon. Nicholas G. Garaufis of the U.S. District Court for the Eastern District of New York. He also served as a student-attorney in an appellate defender clinic. Prior to law school, he worked as a reporter-researcher at The New Republic in Washington, D.C.
Steve has been recognized by Benchmark Litigation as a Massachusetts Future Star and previously on its 40 & Under list in the plaintiff class action category. He has also been honored by Super Lawyers in the New England/Massachusetts jurisdiction and previously as a Rising Star.
