About Us

Home | About Us



Mercer Gastroenterology was established in 1973 by Geobel Marin, M.D., in Trenton, NJ. Over the subsequent four decades, we have been proud to serve patients from both Central Jersey and Bucks County, most of whom we see in our office in Pennington, NJ. We have grown to include five board-certified gastroenterologists along with a large and dedicated nursing and administrative staff. Our mission is to provide outstanding and comprehensive care across the full spectrum of digestive illnesses, and we take pride in treating our patients with respect and a dedicated commitment to their health.

We offer a full range of clinical services in gastroenterology and hepatology, including diagnostic and therapeutic endoscopy, colonoscopy, capsule endoscopy, and motility studies. We specialize in the treatment of a broad array of digestive diseases, including GERD (acid reflux), Barrett’s esophagus, irritable bowel syndrome, inflammatory bowel disease, celiac disease, colorectal cancer screening/prevention, women’s health, and liver disease. We are also excited to announce the addition of new services in 2016, with chromoendoscopy for inflammatory bowel disease and fecal microbial therapy for recurrent or severe Clostridium difficile (c. diff) colitis.

We perform endoscopic procedures at several facilities, including two state-of-the-art surgery centers in Lawrenceville, NJ and Hamilton, NJ, as well as at both campuses of Capital Health System, in Pennington, NJ and Trenton, NJ. We have also seen patients in our satellite office in Hamilton, but as of March 2022 that office is closed.
