Welcome to GDC

Gastroenterology Diagnostic Center

GDC is the premier gastroenterology practice with board-certified gastroenterologists in the Tomball and North Houston areas where we have been delivering state of the art care for over two decades. Our mission is to render the highest quality digestive health care to our patients in the most cost-effective way possible. While our practice employs the latest advances in gastroenterology procedures and uses every cutting-edge technology available, we still believe in building a compassionate and respectful relationship with each of our patients in the friendly manner of ‘old fashioned’ medical arts.

Our facility, located just a few blocks east of the Tomball Regional Hospital, has recently added a state-of-the-art office endoscopy suite. This latest addition provides a convenient and cost-effective alternative to hospital visits for patients undergoing certain procedures. GDC is pleased to be able to provide yet another enhancement to the comfort, well being, and privacy of our patients.
