Although both the program director and program coordinator provide administrative and educational direction for the graduate medical education (GME) training program and although both guide the educational experience of each of trainee over the course of their multi-year program, specifications about the vital role of the program coordinator is not present in the ACGME's common program requirements and nearly missing from scholarly literature (Cottrell, Brownlee, & Ferrari, 2010; Grant, 2008; Norwood et al., 2006). The purpose of this phenomenological study was to explore program coordinators' perceptions of their leadership role in the administration of GME programs through the lens of adaptive leadership. The aim of this study was to add to the scholarly literature the perspective of GME leadership from the vantage point of program coordinators.
