Meet our Core Faculty


The Internal Medicine Residency Program is administered by the program director and the assistant program directors, with the assistance of the subspecialty division directors and three fourth-year chief medical residents.

More than 150 physicians are involved as committed faculty (hospital-based or geographic full-time) for the Internal Medicine Residency Program. Of the 700 physicians in the department, approximately one-half are general internists.

Many of our faculty also hold faculty appointments at the Oakland University William Beaumont School of Medicine, Wayne State University School of Medicine or the University of Michigan Medical School.
