Serving clients with agility and flexibility, Trenam Law has grown into the behemoth law firm of the Tampa Bay Area.

It began with a monstrous name, too. In 1970, Trenam Kemker Scharf Barkin Frye O’Neill & Mullis emerged with just nine attorneys. Today, re-branded as Trenam Law and boasting more than 80 employees, Trenam Law has grown into an entity of its own, and outlived its founders.

Despite Trenam Law’s evolution, it keeps true to its roots as a small, full-service firm. Now with specialized teams that allow the delivery of those services in practice areas ranging from anti-trust law to tax law, and myriad practice areas in between, Trenam has developed a truly broad expertise and continues to evolve in order to better serve its wideranging clients in all areas of law.
