Physicians Supporting You On the Path to Wellness

Learn About Our Gastroenterologists

Serving Patients in Houston

Each of the expert gastroenterologists at Digestive Health Associates (DHA) has a distinct calling to serve patients in the fields of gastroenterology, hepatology, and nutrition. We want to help people, see our patients get well, and encourage them on the path to wellness.

Our team of Houston gastroenterologists is unique because three of our doctors provide interventional GI. This is rare in the field of gastroenterology, as most practices do not provide this service or only have one gastroenterologist trained in this subspecialty.

What Our Patients are Saying

Dr. Dominguez was gracious enough to fit me in with less than a day’s notice. Despite being on his schedule at the last minute, he spent so much time answering all my questions. He is absolutely wonderful, patient, a good listener, extremely knowledgeable, and kind.
