Mercy Catholic Medical Center’s faculty members bring their day-to-day experience of caring for patients into their approach to teaching. Their commitment is reflected in their willingness to share the knowledge and skills they have developed over their professional lifetime. Transitional year residents work side-by-side with physicians in general surgery, internal medicine, radiology, emergency medicine, and primary care among other disciplines to develop the clinical skills they need. Each faculty member, a board-certified physician in his or her specialty, strives to provide a quality and productive experience for residents during the transitional year.
