Dr. Zimmerman graduated from the University of Wisconsin--Madison Medical School, completed internal medicine internship and residency at Abbott Northwestern Hospital, and completed his rheumatology fellowship at Hennepin County Medical Center.
Dr. Zimmerman was born and raised in Neenah, Wisconsin, the youngest of 4 boys. His mom, who may be suffering from some memory loss after the feat of feeding and raising those boys, says he was "never any trouble". He went to Case Western Reserve University in Cleveland, Ohio where he played 2 years of Division III basketball before realizing that he'd better concentrate on academics.
He enjoys playing "monsters" with his young son and, when time allows, running, golf, travel, and Minnesota Gopher basketball.
