About
Regis L. Mullen is the founding attorney of Mullen & Mullen Law Firm in Dallas, Texas, with 59 years of personal injury experience. His practice represents people injured in car and truck accidents, motorcycle crashes, premises liability incidents, workplace injuries, dog bites, and other negligence matters. Mullen also handles wrongful death and traumatic brain injury claims, helping clients pursue compensation after serious accidents and losses.
Mullen earned his B.A. in History from the University of Oklahoma in 1960 and his J.D. from the University of Oklahoma School of Law in 1967. His legal education, combined with decades of litigation experience, provides a foundation for evaluating liability, insurance coverage, damages, and the procedural issues that arise in personal injury cases. He is licensed in Texas and Oklahoma and admitted to the U.S. District Court for the Northern District of Texas.
Before founding his firm, Mullen worked for Allstate Insurance Company as a claims adjuster, senior claims adjuster, and litigation supervisor. That experience gave him direct insight into how insurers investigate accidents, evaluate claims, assess exposure, and manage litigation. He later used that background to establish a practice representing injured individuals in North Texas. His insurance experience supports his ability to anticipate defense strategies and prepare claims with a detailed understanding of the claims process.
Regis L. Mullen is affiliated with the Dallas Bar Association, American Bar Association, Texas Trial Lawyers Association, and American Association for Justice. His long career combines plaintiff-side personal injury work with earlier experience inside a major insurance company. By drawing on both perspectives, Mullen helps injured clients understand claim procedures, evaluate settlement issues, and pursue compensation through negotiation or litigation when necessary.
