Firm History

In July of 2004, Byron, Carlson, Petri & Kalb, LLC, was formed when Chris Byron, Brian Kalb, and Chris Petri left the law firm of Gallop, Johnson & Neuman in Clayton, Missouri, and joined David Gerber in establishing their own law practice. We chose Edwardsville because of the long-standing community ties that our attorneys have to the area.  As a small law firm, we have flexibility in taking cases and are able to provide cost-effective legal services. This works to the advantage of our clients as our client base continues to grow.

At Byron, Carlson, Petri & Kalb, LLC, we work diligently to protect our clients' interests. Using our in-depth knowledge of the law, investigation of the facts, courtroom advocacy, and a strong work ethic, we endeavor to get the absolute best results possible for each and every one of our clients.
