The Division of Infectious Diseases offers a wide range of inpatient and outpatient clinical services related to the care of patients with infectious diseases. We have four main missions: patient care, education, research and community health improvement. The primary goal of our clinical programs is to provide excellent inpatient and outpatient care and consultative services to the patients receiving care at Froedtert Hospital, the VA Medical Center and our regional partners. Our education mission includes efforts across a broad spectrum of learners, including medical and other health care professional students, residents and fellows, and continuing education for practicing physicians, as well as community education in areas of infectious diseases.
