2022-2023 Chief Residents 


Meet our chief medical residents who serve as key leaders for our program and who work together as a team to serve the mission of Temple's residency, hospital, and community. They are selected from among our own residents during their PGY2 year for excellence as clinicians, as educators, and as leaders. The chief year is an additional PGY4 year completed at the end of their residency and an opportunity for our chiefs to give back to our program. In addition to teaching our residents during their clinical service as attending physicians on the inpatient floors and outpatient clinic, they also play a large role in the residency's didactic curriculum as curriculum developers, coordinators, and teachers. They support our residents as some of their most powerful representatives and advocates and are the driving force behind many of the innovations which enrich our program and Temple community.
