About the Firm


Lyons & Clark, Inc. was established in 1986 when Mark Lyons and Cary Clark left the Tulsa County District Attorney's Office after a combined total of 17 years in the criminal and civil divisions.  Following the untimely death of Mr. Clark in 1988, the firm continues its tradition of a litigation-based practice in federal and state court, representing businesses and individuals.  This firm takes great pride in its dedication to providing personal service to the client.
