Scholars, mentors and partners in good health

Kennestone GME faculty and staff share a passion for the practice of community medicine. Committed educators skilled in adult learning theory pursue specialties in areas like public health, healthcare administration, epidemiology and healthcare disparities.

“I’ve always loved teaching and it is a humbling honor to be involved in the development of graduate education at WellStar, especially since I was born in Kennestone Hospital.”
