Serving the Gastroenterology Needs of Our Patients

Since 1999, Digestive Health Associates (DHA) has provided healthcare services in the fields of gastroenterology, hepatology, and nutrition for patients throughout the Greater Houston area, including West Houston and Katy.

Our team of physicians includes Dr. G.S. Ramesh, MD, Dr. J. George Sun, MD, Dr. Cristian E. Dominguez, MD, and Dr. Joseph T. Krill, MD. In total, our gastroenterologists have more than 30 years of experience in the diagnosis and management of GI disorders.

We attribute our longevity to a proven track record of providing patient-centered care. We focus on building long-term relationships with our patients so that we become invested in their wellness.

One of the ways that we provide the best care for patients is by offering specialty procedures that require extensive training and expertise beyond the capabilities of a typical gastroenterologist. We are committed to staying up-to-date and modern with our services so that we can meet the latest health needs of our patients.

Our practice is unique in that three of our doctors (Dr. Sun, Dr. Dominguez, and Dr. Krill ) are interventional gastroenterologists capable of performing ERCP (Endoscopic Retrograde Cholangiopancreatogram) and EUS (Endoscopic Ultrasound) procedures. Dr. Krill is trained in endoscopic bariatric procedures.

Our practice is also a reflection of the multi-cultural makeup of Houston. We are a very diverse practice made up of four expert physicians that speak four distinct languages and a diverse office staff that is ready to support your exam needs. Our distinct backgrounds link us together so that we can best serve our patients in a manner that is comfortable for them.

We are also fortunate to be affiliated with Memorial Hermann. Our practice is located inside the renowned Memorial Hermann Memorial City Medical Center in West Houston, enabling us to reach patients from just around the corner in Houston or across the globe coming to Memorial City seeking world-class medical treatment.

For the patients that we are privileged to serve, we are here to help you on the path to wellness. We encourage you to learn more about our physicians, clinical staff, and involvement in the medical community — both locally in Houston and through our contributions to the advancement of gastroenterology.
