Marcy grew up in Columbia, Maryland and is the proud principal of Wilde Lake High School for Howard County Public Schools. She earned a B.A. in History from Haverford College, a M.A. in Education from Wake Forest University, and advanced to candidacy for a Ph.D. at the University of Maryland at 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 scores and participation, and staff and student engagement. As Community Superintendent for Howard County Public Schools from 2017-2019, she had the honor of supporting the amazing 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 Wilde Lake.
In addition to her work for Howard County Public Schools, Marcy is a member of the Leadership Howard Premier Class of 2019, served as a member of the Board of Trustees for the Community Foundation of Howard County, and has run 20 marathons, raising over $20,000 for the Leukemia and Lymphoma Society. She is an adjunct faculty member for McDaniel College, teaching graduate courses for aspiring school leaders. She was a recipient of the Washington Post Distinguished Educational Leadership award, has been named the Howard Magazine Principal of the Year nine times, and was recognized with the City Gives Leadership Award, Maryland PTA Educator of the Year award, and the Arts Education in Maryland Schools Leadership Recognition Award.
