Head of School, Marianne Grace

“It is an honor and a privilege to lead Merion Mercy Academy where we take seriously our commitment to empowering students to lead, learn and serve. Grounded in spiritual development and academic and personal excellence, a Merion Mercy education graduates exceptional young women who are prepared to change the world.” 

Our Head of School, Mrs. Marianne Grace, possesses decades of mission-driven leadership experience and an impressive professional background. In addition to being a past Merion Mercy parent (daughter Kelly ‘04), former chair of the Board of Trustees, and previous Director of Operations, Mrs. Grace spent 20 years as Executive Director of Delaware County. In that role, she managed a total budget of approximately $600 million, as well as 50-plus departments and 20 direct reports. Dedicated to her Catholic faith and active in her community, she has served on the boards of Trinity Health Mid-Atlantic Region, Mercy Health System, Mercy Catholic Medical Center, Community YMCA and Holy Child Academy. 

Mrs. Grace holds a bachelor’s degree in History from Temple University, a master’s in Health Education from Saint Joseph’s University, and a master’s in Public Administration from Widener University.
