Led by division director Mohammad Al-Haddad, MD, the Division of Gastroenterology and Hepatology within the Department of Medicine at IU School of Medicine has a distinguished tradition of innovation in research and education and a demonstrated excellence in patient care. This is one of the largest divisions of its kind in the United States, offering an enormous breadth of clinical and research expertise for learners and faculty peers. 

The division was founded by Dr. Philip Christiansen in 1958 and flourished under the leadership of Drs. Lawrence Lumeng (Division Director from 1984–2007), Naga Chalasani (Division Director from 2007–2020), and Glen Lehman (Clinical Director from 1985–2005) to national prominence. The division has enjoyed significant growth to faculty and fellowship size, patient and procedural volume, and the federally-funded research program.

Our prized Advanced and Therapeutic Endoscopy Program is world-renowned with over 8,000 procedures performed such as ERCP, EUS, endoluminal therapies and third space endoscopy in a state-of-the-art recently renovated suite. This space was formally named in 2020 through a $1 million endowment, the “Lehman, Bucksot and Sherman ERCP Suite” – honoring Dr. Glen Lehman, longtime ERCP charge nurse Lois Bucksot, RN, and Dr. Stuart Sherman. In addition, we offer unique and highly specialized services in hepatology, transplant hepatology, colon cancer screening, inflammatory bowel disease, upper and lower GI motility, medical and endoscopic weight loss, and familial and hereditary GI conditions.

Our main outpatient surgical center has been named after Dr. Glen Lehman in recognition to his numerous contributions to the field of endoscopy. In addition to our traditional Academic Health Center-based clinics and endoscopy suites, the division offers ambulatory and procedural practices at Spring Mill, IU Health North hospital, and IU Health Saxony Hospital. Our endoscopy suite on the North side has been named after Dr. Douglas Rex, a world-renowned endoscopist and a pioneer in colorectal cancer screening. In continuing the tradition started nearly 30 years ago, the division has a robust outreach clinical program where faculty clinicians have established practices in the towns surrounding Indianapolis.
