A litigator with three decades of experience, Sonya Winner handles high-stakes civil cases for clients in a wide range of industries, including banking, pharmaceuticals and professional sports.  She has handled numerous antitrust and consumer disputes, many of them class actions, in state and federal courts across the country.

Sonya’s cases typically involve difficult technical issues and/or complex legal and regulatory schemes. She is regularly able to resolve cases before the trial phase, often through dispositive motions. But when neither summary judgment nor a favorable settlement is an option, she has the confidence of her clients to take the case all the way through trial and on appeal. Her recent successes have included a cutting-edge decision rejecting a “true lender” challenge to National Bank Act preemption in a class action involving interest rates on student loans, as well as the outright dismissal of a putative antitrust claim against the National Football League and its member clubs asserting an unlawful conspiracy to fix cheerleader compensation. 

Sonya has been recognized as a leading trial lawyer by publications like Chambers and the Daily Journal. She is chair of the firm’s Class Action Litigation Practice Group.
