Teaching Service Leadership and Faculty

The Department of Medicine teaching faculty is comprised of board-certified physicians from three medical service groups:


Teaching Service Faculty

Inova Fairfax Hospitalist Group is a group of board-certified internal medicine physicians who admit and care for patients at Inova Fairfax Hospital. In addition to being excellent clinicians, they also excel in teaching residents and medical students. The group has admitting privileges to the teaching service and also participates in noon conferences, morning report conferences and teaching didactic sessions.

Hospitalists work in conjunction with private practice primary care physicians to provide medical care to hospitalized patients. While the hospitalist program does not replace specialty physicians such as cardiologists and gastroenterologists, it ensures a physician is present in the hospital to see patients throughout the day, meet with families and assist with prescriptions and discharge planning.

Once patients are discharged, the hospitalist sends documentation to the primary care physician about the patient's hospitalization.
