David Gringer

David Gringer is an accomplished trial lawyer with a focus on complex antitrust and consumer protection litigation. Mr. Gringer is one of the very few attorneys to have successfully tried cases under section 7 of the Clayton Act for both plaintiffs and defendants, and has recently prevailed at trial in different cases brought by the Attorneys General of 16 different states. Drawing on his experience as a trial attorney in the Antitrust Division of the US Department of Justice (DOJ), Mr. Gringer also routinely advises clients responding to government investigations at the state and federal levels. Whatever the legal problem, Mr. Gringer understands that effective representation depends on having a full understanding of the industry at issue.

At the DOJ, Mr. Gringer played a leading role in many of the Antitrust Division's highest-profile matters, including serving as a member of the division's winning trial teams in U.S. v. H&R Block—the division's first successful challenge to a merger in more than eight years—the e-books price-fixing litigation, and writing the division's litigation complaints in U.S. v. Anheuser-Busch and U.S. v. U.S. Airways.

In 2013, Mr. Gringer was selected for an individual Assistant Attorney General Award of Distinction for his work on U.S. v. H&R Block, U.S. v. BlueCross Blue Shield of Michigan, and the proposed and later abandoned 3M/Avery merger, among others.

Before joining the DOJ, Mr. Gringer served as a law clerk to the Honorable Michael Boudin of the US Court of Appeals for the First Circuit. He also has substantial political campaign management experience. During 2005, he was campaign manager for the successful Manhattan Borough president campaign of Scott Stringer, who now serves as New York City comptroller.
