Our Firm’s History

In July 2004, our law firm was formed when Chris Byron, Brian Kalb and Chris Petri left the law firm of Gallop, Johnson & Neuman in Clayton, Missouri, to establish their own law practice. We chose Edwardsville because of the longstanding 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.

In July 2010, Carlson & Carlson, P.C., merged with Byron Gerber Petri & Kalb, LLC, to become Byron Carlson Petri & Kalb, LLC. The Carlson Group brought extensive background and knowledge in the areas of wrongful death, medical malpractice, personal injury and mediation to the firm’s already broad practice range of commercial litigation, real estate transactions, corporate formation, estate planning and criminal defense.
