Your Team

Alamo City Bariatrics offers a wide variety of weight loss options, both surgical and non-surgical treatment plans to include: laparoscopic gastric bypass, sleeve gastrectomy, duodenal switch, gastric balloon, gastric banding, and other minimally-invasive procedures. Dr. David Thomas is the founding physician of Alamo City Bariatrics and also serves as medical director of bariatric surgery at Northeast Baptist Hospital and a fellow of the American Society of Metabolic and Bariatric Surgery (ASMBS). He is a board-certified general surgeon whose passion for bariatric surgery was ignited during his service as a staff surgeon in the United States Air Force.

Dr. Thomas’ commitment to weight loss surgery is fueled by the positive impact it has on individuals. He has witnessed remarkable outcomes, including diabetes cured, high blood pressure resolved and obstructive sleep apnea eliminated. Patients who once struggled to walk down the block now run half-marathons. Parents and grandparents who could not engage in physical activities with their children and grandchildren, are now able to walk, run and play with their families. If you are considering a weight loss program to improve your health and lifestyle, Dr. Thomas encourages you to not wait and to call Alamo City Bariatrics to schedule a consultation.

“What I like most about being a bariatric surgeon is the ability to change people's life in a dramatic and meaningful way. Bariatric surgery allows people to be more active and participate with their family in ways they couldn't prior to weight loss.” –Dr. David Thomas
