5+ Years of Medical Experience


Dr. Rene Leon has been in practice for over 20 years with Texas Regional Asthma and Allergy Center, in Southlake, Texas. He taught at the University of Texas Southwestern Medical School in Dallas and served as a Clinical Associate Professor with the Division of Allergy and Immunology.

As a practice owner, my goal is to make sure your experience at Texas Regional Allergy and Asthma Center is absolutely the most professional and enjoyable medical experience that can be provided.”
