Our roots date back to 1932 when the firm was founded by Karl Williams and John C. McCarthy. Our founders began and expanded the firm by strict adherence to the principles of service, competence and integrity. Through their efforts, and of those that followed, the firm developed a long history of leadership and success in and out of the courtroom. To maintain that tradition, we choose our lawyers carefully. New attorneys must not only have outstanding academic credentials, but also a commitment of service and leadership to the communities that we serve.

A lot has changed since 1932. Our firm has grown to become one of the largest in the region - located in state-of-the-art offices. The legal needs of our clients have become more complex and the practice of law has changed in ways our founders could never have imagined. But some things never change. At WilliamsMcCarthy LLP, the trust of our clients remains our most valued asset. We work hard to maintain that trust by bringing the full commitment of a highly trained team of lawyers to every project - every client - every day - just as we've always done - for more than 85 years.
