Mary Kate Blaine » Biography


Mary Kate Blaine began her service as Trinity Hall’s second head of school in July of 2021. Prior to that, Kate served as the principal at Georgetown Visitation Preparatory School, an all-girls Catholic high school in Washington, D.C., beginning in 2013. She previously held the role of chief of staff to the superintendent of Catholic schools for the Archdiocese of New York. Kate began her career in education as a social studies teacher at the Notre Dame School of Manhattan, an all-girls Catholic high school in New York City, where she later served as social studies department chair and director of curriculum development.
Kate earned her B.A. in American studies from Fordham University and holds two graduate degrees from Columbia University: an Ed.M. in private school leadership and an M.A. in history and education.
When not at school, Kate loves doting on her nieces, nephews, and godchildren; slowly but steadily training for road races; following current events and all manner of political punditry; and cheering for the Philadelphia Eagles (even when they break her heart).
