Practice Overview

Ellen Shammash, MD, is a native of Massachusetts. She graduated from Middlebury College with a Bachelor of Arts (BA) in Biology. She received her medical degree from the New York University School of Medicine, followed by Internal Medicine Residency and Rheumatology Fellowship at the University of Minnesota. She practiced Rheumatology for many years at Regions Hospital and Health Partners Specialty Clinic, where she participated in the training of residents and fellows from the University of Minnesota. She resides in Eagan, MN with her husband, Douglas Hotvedt, MD. They have three lovely daughters.

The field of Rheumatology encompasses a complex array of autoimmune and inflammatory conditions which may affect multiple organ systems throughout the body and often lead to chronic disease. Dr. Shammash chose Rheumatology for the broad spectrum of diseases and the ability to form lasting relationships with my patients. It is these relationships and the ability to assist with quality of life that have made her career most rewarding. Dr. Shammash combines the most up-to-date science with an analytical and compassionate approach to diagnosis and treatment, using shared decision making to construct a personalized and successful plan for her patients.
