About Gastrointestinal Associates

We are delighted to welcome you to Gastrointestinal Associates (GIA). Our dedicated physicians and staff will evaluate and treat your gastrointestinal disorders with sensitivity, compassion, confidentiality and professionalism. We regard the doctor/patient relationship as sacred and believe that it is built upon trust and mutual respect.

Gastrointestinal Associates was founded in 1972 by William Mahood, MD, the first board certified gastroenterologist on staff at Abington Memorial Hospital and Holy Redeemer Hospital and the first to introduce modern GI techniques, including endoscopy and colonoscopy, to Montgomery County. Over the past 50 years, the practice has grown steadily and has added expertise in a wide range of GI diseases and techniques. With offices in Jenkintown and Chalfont, we now serve Philadelphia, Montgomery, and Bucks Counties.

Our current staff of 20 professional health care providers is ethnically diverse and includes 7 women. All physicians are board-certified in Gastroenterology and treat a broad array of gastrointestinal illnesses and complaints. We perform standard endoscopic procedures such as endoscopy, colonoscopy, sigmoidoscopy and esophageal dilation, as well as a number of specialized services and programs.

Our mission at Gastrointestinal Associates is to be a caring team of physicians and staff dedicated to providing patients and referring physicians with unsurpassed gastrointestinal services.
