Isaac Colunga is a Partner in the firm’s Business Litigation Group and works in the Chicago office. Isaac represents clients in consumer class actions, contract and commercial disputes and employment cases.

The TCPA, FCRA and Other Consumer Class Actions
For years Isaac has defended clients in Telephone Consumer Protection Act (TCPA) and Fair Credit Reporting Act (FCRA) cases filed in federal courts around the country. He has served as lead or co-counsel in well over 100 TCPA and FCRA class actions nationwide. He’s obtained favorable class and individual settlements; he’s had cases dismissed; he’s won on summary judgment; and he’s defeated class certification. Because of his experience, Isaac has developed relationships with members of the plaintiff’s bar that routinely file these suits, and many clients rely on Isaac to provide compliance counseling before starting fax, phone call and text messaging campaigns. Isaac’s clients range from middle market companies to multi-national corporations that hail from a variety of industries, such as pharmaceutical, retail, communications, supermarket chains, software and technology, healthcare, information and delivery, cosmetics, consumer goods and staffing.
