Adult Gastroenterologists

We are proud to offer patients excellence in comprehensive GI care across all our locations in north Texas. All of our gastroenterologists are board certified, and many have completed fellowships in advanced endoscopy. This means that our doctors are equipped with extensive specialty knowledge and training beyond medical school and medical residency. We are able to offer patients treatment for a full spectrum of GI disorders, from general to advanced procedures.

Our results reflect this, and our colonoscopy performance is a good example. The quality of a colonoscopy screening is measured by the percentage of people screened who have polyps detected, which may be cancerous or non-cancerous. This is known as the ADR, or adenoma detection rate. At DHAT, our ADR is 37% -- about fifty percent higher than the 25% national benchmark. This shows that the colonoscopies performed by our skilled physicians are highly effective in helping to detect colon cancer early.


Primary care doctors should know that DHAT gastroenterologists are committed to working closely with referring physicians and communicating often to coordinate the patient’s overall care. Please call us at 800-425-3759 to learn more about referring a patient.
