A world-class environment. This building was designed to create an exceptional experience for patients and physicians. The welcoming environment is supported by advanced technology and access to medical services throughout Northwestern Medicine.

Further integrated patient care experience. From clinic appointments and procedures to diagnostic tests and follow-up care in nutrition and counseling services, we provide a multidisciplinary approach to digestive health care.

4worldlovers: Dr. Cohen practices General Gastroenterology with additional special focuses on Crohn's Disease, Ulcerative Colitis, and non surgical treatment of hemorrhoids. Dr. Cohen is originally from Potomac, Maryland. He completed his undergraduate work at Cornell University and medical school at the University of Maryland. Dr. Cohen moved to Chicago in 1998 where he completed his residency at Northwestern followed by a 4 year combined clinical and research GI fellowship under an NIH training grant at the University of Chicago. He has been in practice at Northwestern since 2005.

Dr. Cohen is board certified in Gastroenterology and is a Clinical Associate Professor of Medicine at Northwestern University.

He is actively involved in teaching medical students as well as GI fellows, and has received multiple teaching awards from the Northwestern University Feinberg School of Medicine.

Dr. Cohen's practice philosophy is simple: he takes care of his patients the way he would want any doctor to take care of him. Appointments are as long as they need to be. Phone calls and electronic messages to the doctor are always returned by the doctor himself, and usually within a few hours. Dr. Cohen is part of the private practice community at Northwestern Memorial Hospital.

Dr. Cohen is married with three children and one dog. He spends his free time with his family, building model rockets with his kids, skiing in the winter, and volunteering as camp doctor at his kids' summer camps in the North Woods of Wisconsin.
