What is a gastroenterologist? 

A gastroenterologist is a physician who has completed a full course of training in internal medicine plus three additional years specializing in disorders of the upper and lower digestive tract, liver, gallbladder and pancreas. That training includes intensive development of skills such as diagnostic and therapeutic colonoscopy and endoscopy. A gastroenterologist also has expertise in diet and nutrition.

Get to know our providers. Our highly qualified physicians are all board certified by the American Board of Internal Medicine and the Subspecialty Board of Gastroenterology and have been trained in leading institutions in the country, including Medical College of Virginia, Duke, Harvard, Massachusetts General, Johns Hopkins, North Shore University, National Naval Medical Center, and Mayo Clinic. Continuous post-graduate studies provide assurance that our physicians are abreast of the very latest in advanced medical technology.

AAAHC

In January 2009, the practice endoscopy center was re-accredited by the Accreditation Association for Ambulatory Health Care (AAAHC). Accreditation distinguishes this surgical center from many other outpatient surgical facilities by providing a safe work environment and the highest quality for our patients. Status as an accredited organization means Gastroenterology, Ltd. has met nationally recognized standards for the provision of quality health care, outlined by the association.

"We believe our patients deserve the best," states Dr. Alan Ganderson. "When you see our certificate of accreditation, you will know that the AAAHC, an independent, not-for-profit organization, has closely examined our facility and procedures. It means that we, as an organization care enough about our patients to strive for the highest care possible." According to Dr. Jan Janson, director of Continuous Quality Improvement at the time of accreditation, "Going through the process of accreditation challenged us to find better ways to serve our patients, and it is a constant reminder that our first responsibility is to our patients and the quality of care we provide."
