Program Administrator

I began my career in GME in 2013 at UNC Chapel Hill as fellowship coordinator over Pain Medicine, Pediatric Anesthesia, and OB Anesthesia. My husband’s career brought us down to Tampa in 2015 where I joined USF as the GI/Hepatology Fellowship Coordinator. After a year away in 2021 at HCA Florida Brandon Hospital as their Internal Medicine Program Coordinator, I returned to USF to join the Internal Medicine Residency program as the Program Administrator in 2022.

I live in Riverview with my husband and two boys. I love crafting in my spare time, what spare time I get as a mom of two young boys, and frequently sell my items at local craft fairs.
