University of South Florida

I'm currently working as an Assistant Professor in the University of South Florida Physician Assistant Program. On Fridays, I continue to provide care to patients that require same day (acute care) appointments for USF Family Medicine.

I provide comprehensive medical care to children from birth to age 21. This includes care for acute problems and health maintenance, along with a multitude of pediatric issues. I also serve as the Program Director for the residency program and the Vice-Chair for education. I have been involved in academic medicine since completing my Chief Residency year. Much of the care I provide is in conjunction with USF medical students and pediatric residents in USF outpatient clinics.
