I completed medical school close to home at the University of Rochester (2013), emergency medicine residency at Maine Medical Center (2016), and a pediatric emergency medicine fellowship down South at Wake Forest University (2018). Now, I am back in Maine for good! I wear many hats at Maine Med including EM Residency Assistant Program Director, and I am heavily involved in the pediatrics didactic and simulation curriculum for our trainees. In 2020, I also began as the Medical Director for the Maine EMS for Children (EMS-C) Advisory Committee, and pediatric representative to the EMS Medical Directions and Practice Board.
