Meet Our Team: Bariatric Surgery

Experts at the Weight Loss and Metabolic Center at Baylor St. Luke’s Medical Center specialize in bariatric (weight loss) surgery and surgical treatment of metabolic diseases. Our highly experienced team consists of nationally-recognized bariatric surgeons, gastroenterologists, nurses, clinical health psychologists, registered dieticians, and medical assistants. To ensure our patients are successful in their weight-loss journey, our team includes critical team members that are present throughout the entire process, including program coordinators, insurance specialists, and schedulers. 

We are committed to helping our patients achieve long-term weight loss success and improved health by eliminating life-threatening obesity-related conditions, like diabetes and hypertension.

We believe a collaborative, multidisciplinary approach is crucial to ensuring the best possible care, outcome, and long-term weight loss for bariatric patients. We work closely with a variety of specialties from across Baylor Medicine.
