At Clinical Gastrointestinal Associates, our mission is to provide outstanding patient care. Founded in 1993, our practice has served the lower Bucks County community with personal and prompt attention to our patients’ medical needs. We provide evaluations and treatments of disorders of the gastrointestinal tract, including the esophagus, stomach, small intestine, colon, pancreas, gallbladder, and liver, at our main office and local hospitals.  We believe in continuity of care for our patients who may be admitted to the hospital by making rounds 7 days a week at both Lower Bucks Hospital in Bristol and St. Mary Medical Center in Langhorne.

The physicians of Clinical Gastrointestinal Associates are university-trained in Philadelphia and are board-certified in gastroenterology. They are members of the prestigious American College of Gastroenterology, in addition to other local, state, and national organizations. They have extensive experience in diagnosing and treating digestive illnesses by virtue of treating thousands of patients every year and performing more than 2,500 endoscopic procedures every year.

Patients who need an outpatient sigmoidoscopy, colonoscopy, upper endoscopy, or endoscopy procedures have them performed at our state-of-the-art endoscopy center — The Endoscopy Center of Bucks County — in Newtown. The center is located just minutes from the Langhorne main office, is licensed by the state and Medicare, and accredited by the AAAHC. Undergoing their procedures at the center allows patients to have them more conveniently and in more comfort and privacy than in other settings.

The main office is centrally located in Langhorne, near Oxford Valley Mall, with convenient scheduling and plenty of parking.  Our friendly and attentive office staff strives to address our patients’ concerns quickly, and ensures that patients get appointments promptly when they need to be seen.
