Geoff Irwin is a trial lawyer with a broad range of complex civil litigation experience, particularly in antitrust and bankruptcy litigation.

On the antitrust front, Geoff was part of the winning trial team in FTC v. STERIS Corporation, in which two medical product sterilization companies defeated the Federal Trade Commission's effort to block their merger. He was the lead litigator in the successful combination of two West Virginia hospitals after the FTC decided to withdraw from further litigation. And he was one of the principal courtroom lawyers for Aetna at the government's closely watched trial challenging the proposed merger of Aetna and Humana in late 2016. He also has counseled merger partners receiving antitrust scrutiny from federal agencies in other contexts, resulting in successful outcomes in the Miller/Coors, XM/Sirius, and Hertz/Dollar Thrifty combinations.

Geoff's trial experience also extends to bankruptcy litigation, where he has represented clients in numerous industries seeking to reorganize. He supported Chrysler Corporation's successful emergence from its bankruptcy proceedings and has litigated against opponents to asset sales in various contexts. Most recently, Geoff was a member of the City of Detroit's trial team in its highly publicized municipal bankruptcy proceeding, which resulted in a court-approved plan of adjustment after 16 months of litigation, and has assisted at other bankruptcy-related hearings and trials.

Additionally, Geoff has litigated commercial disputes involving various industries and legal claims, including cases with allegations of securities fraud, accounting fraud, deceptive trade practices, FTC Act violations, and environmental remediation. He was part of the winning trial team in Anchor Savings Bank v. United States, a leading Winstar judgment against the federal government.
