Andrew Kassof

Andrew Kassof leads Kirkland’s litigation practice globally and serves on the Firm’s Executive Committee. Andrew has spearheaded the enormous growth of Kirkland’s litigation practice over the last several years. Bloomberg Law profiled that rapid growth in an article in 2025. As part of that expansion, Kirkland has added industry-leading talent across various types of litigation while opening and growing new offices for litigation in Salt Lake City, Boston, Miami, Philadelphia and Nashville. Kirkland now touts top-of-the-market practitioners across commercial litigation, product liability and mass torts, securities, antitrust, IP, government regulation, internal investigations and enforcement, private equity, sports and entertainment, real estate and other areas in offices around the globe. Andrew also leads Kirkland’s alternative fee program, which has expanded dramatically over the last five years. In his practice, Andrew has earned multiple “Litigator of the Week” awards by The American Lawyer. In one case, the court “adopted” Andrew’s oral argument as “the grounds for its opinion” after “finding that Mr. Kassof’s exposition, explanation, and reasoning aligned with what I would write in a written opinion.” Andrew’s commercial litigation practice cuts across different industries and types of cases, including life sciences, healthcare, oil and gas, sports and entertainment, private equity and other industries. Twice he has tried billion dollar cases to successful verdicts — once on the plaintiff side in a fraud-based suit in federal court in NY, and the other for the defense in a False Claims Act case in Texas; has first-chaired many additional trials in various jurisdictions and in arbitration; and has successfully represented clients in different types of complex commercial disputes, False Claims Act suits, class actions, and other cases in state and federal courts in nearly every state in the country.
