About Marlana Radcliffe, M.D.

Dr. Marlana Radcliffe grew up in Broomfield, Colorado before heading to the east coast to earn her undergraduate degree at The University of North Carolina (UNC). She completed medical school at New York Medical College and then residency at the Icahn School of Medicine at Mount Sinai in New York City. There, she developed a passion for and started research in inflammatory bowel disease. She completed her gastroenterology fellowship at Temple University in Philadelphia. Dr. Radcliffe returned to UNC for an extra year of training in the care of patients with inflammatory bowel disease, before making her way back to Colorado to join South Denver GI.

Patient Care Philosophy

I believe in providing patient-centered care tailored to each individual’s needs. Everyone’s experience is different, and I always listen to patients to make sure that I understand their experiences, so that we can come up with the best plan together to get them on the path to healing.
