My extensive experience handling class action lawsuits—coupled with my work in advertising compliance—allow me to provide clients with full-service representation.

Claudia focuses her practice on the defense of consumer class actions and on complex commercial litigation, including unfair business competition, false advertising, product liability, and privacy matters. She is currently representing numerous consumer goods manufacturers and retailers in false advertising and mislabeling class action lawsuits. Claudia also regularly counsels clients in the food, cosmetics, retail, and technology industries. She represents companies in false advertising disputes before the National Advertising Division (NAD) of the Council of Better Business Bureaus, Inc.
