MCMC Osteopathic Program Faculty

The Osteopathic Program shares the same faculty with the Internal Medicine Residency Program at Mercy Catholic Medical Center (MCMC).

The faculty consists of more than 80 full-time, part-time and voluntary physicians who possess outstanding academic qualifications and are dedicated to developing skilled physicians who are well prepared to meet today’s health care challenges. MCMC physician-educators actively participate in all aspects of the program's curriculum, which has greatly added to residents’ patient interactions.
