Erik Grossmann, MD, has more than two decades of experience as a surgeon who focuses on patients with intestinal problems. These issues can include conditions such as inflammatory bowel diseases and colorectal cancers. When he meets new patients, his first goal is to make them feel comfortable and let them know MU Health Care has a team of experts that can help them get better. His favorite part of the job is visiting with people five years after their cancer surgery and telling them they are cured.

Dr. Grossmann grew up in St. Louis and got interested in medicine as a boy, when he used the knowledge he learned in a Cub Scouts first-aid class to help his mom when she cut her hand in the kitchen. In his free time, he enjoys spending time with his wife and two children, cooking, camping and playing guitar in a garage rock band.
