Headquartered in Rockford, Illinois, we are in the heart of the rapidly expanding corridor between Chicago and Madison.

A Proud Tradition For Almost 90 Years
WilliamsMcCarthy LLP traces its origins to 1932, when Karl Williams began his practice in Rockford.
Original Practice House

Mr. Williams soon formed a partnership with John McCarthy and John Kinley; an association that endured for nearly fifty years, until Mr. Williams’ death. Our founders focused on a strict adherence to the principles of service, competence, and integrity. Central to their philosophy was the belief that the firm’s attorneys not only have outstanding academic credentials, but also a commitment to leadership within the communities we serve.

A lot has changed since 1932. WilliamsMcCarthy LLP has grown to become one of the most respected firms in the region. Our clients’ legal needs have become more complex, and the practice of law continues to evolve in ways our founders could never have imagined. What remains unchanged is our commitment to earn the trust of our clients and communities through the talents of a highly trained team of lawyers dedicated to delivering for every client and every project.

Commitment to Community

WilliamsMcCarthy LLP is committed to giving back to the communities that give so much to us. Our attorneys contribute in a variety of ways: free legal services to low-income individuals and families; active leadership on community and nonprofit boards and committees; and active involvement in youth activities, churches, and other community organizations.
