Dr. Leon has been in practice for 15 years with Texas Regional Asthma and Allergy Center, in Southlake, Texas. Growing up as the son of a physician in South Florida and having been exposed to medicine as a child, sparked an interest in the medical field.

Actively involved in teaching at the University of Texas Southwestern Medical School in Dallas, he serves as a Clinical Associate Professor with the Division of Allergy and Immunology. This position provides Dr. Leon the opportunity to spend time at the Allergy and Immunology Clinic at UT Southwestern Parkland Memorial Hospital, allowing him to interact with students and faculty as well as interesting patients not commonly seen in the private practice setting. He also enjoys providing students, residents and Allergy and Immunology Fellows, the opportunity to rotate into the office, which allows them to experience the private practice setting. “As an allergist, my number one goal is to take the best possible care of my patients and to provide them an improved quality of life. 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.” More Information... |

Chris has always loved pediatrics, but is very comfortable and enjoys caring for patients of all ages. She likes to focus on patient education as much as possible, believing that we can be better partners in health care if we understand what and why a specific treatment plan is implemented.
Chris lives in Grapevine, TX with her husband Kevin. They have 3 boys who are graduates of Grapevine High School. In her spare time, which is seldom available, Chris works with the high school youth group at church, where she is frequently designated as the “official nurse” for youth events. She also enjoys reading, quilting, helping with her great nieces and nephew, and singing in the church choir, which is conveniently directed by her husband. More Information... |
