Marcy grew up in Columbia and is the proud Principal of Wilde Lake High School for Howard County Public Schools (HCPSS). She earned a bachelor’s in history from Haverford College, a master’s in education from Wake Forest University, and a Ph.D. at the University of Maryland College Park. 

Her career as an educator began as a social studies teacher and assistant principal at Wilde Lake High School. In 2005, she had the unique opportunity to return to her alma mater, Atholton High School, to serve as principal for five years. She then had the privilege of serving as the principal of Hammond High School from 2010-2017. While serving as the principal at Hammond, the school made substantial gains in numerous areas, while simultaneously closing achievement and opportunity gaps for traditionally underserved students, including on-time graduation rates, college enrollment, SAT scores, Advanced Placement (AP) scores and participation, and staff and student engagement. As Community Superintendent for HCPSS, she had the honor of supporting the incredible students, staff, and administrators in 26 Howard County schools. In July 2020, Marcy had the great opportunity of returning to Wilde Lake High School to serve as principal. She is ecstatic to be working with the students, staff, families, and community in the area.

Outside of her full-time profession, she is an adjunct faculty member for McDaniel College, teaching graduate courses for aspiring school leaders.
