Jack Baumann is an experienced litigator who has represented a diverse group of clients (from start-ups to Fortune 500 companies) in high stakes commercial litigation in state and federal courts and arbitrations throughout the country.  He has assisted clients in navigating all stages of litigation, from initial pleadings through trial and appeal.

A large portion of Jack’s practice focuses on class action defense, and he has successfully defended more than 50 class actions, including cases involving the “right of publicity,” the Fair Credit Reporting Act (“FCRA”), wage-and-hour, the Americans with Disabilities Act, tribal lending, securities and consumer fraud.  He has assisted clients not only with the complexities of litigation, but also managing media exposure, responding to Congressional inquiries, and liaising with governmental agencies to ensure the best possible outcomes.   

Before joining the firm, Jack clerked for the Honorable Jerome Farris on the United States Court of Appeals for the Ninth Circuit.
