AGMG has offices in Anaheim and Orange, California. We are affiliated with AGMG Endoscopy Center, which is a state of the art facility with AAAHC accredidation and Medicare certification. The endoscopy center is equipped with the newest and finest endoscopic equipment and is staffed with an expeerienced nursing team. It is one of the few centers in the nation to have an anesthesiologist available full time. This allows us to offer Propofol deep sedation (which can only be delivered by an Anesthesiologist) and it provides the ultimate in patient comfort and safety.
All of our physicians have extensive knowledge and experience in gastroenterology and liver diseases. Our commitment to research gives our patients the benefit of being able to frequently experience the therapies of tomorrow as well as the best medicine and practice of the present. The doctors of AGMG serve as both Gastroenterology consultants and, frequently, as primary care doctors, as we are well skilled in the practice of internal medicine.

AGMG physicians have worked on projects with most of the pharmaceutical companies in the United States and abroad and are consulted almost weekly on the development of new treatments in the field of Gastroenterology and Liver disease. We consider our research capabilities as a way of offering frequently cutting edge therapy to our patients at no cost.
