Mary Kate Blaine Named as Trinity Hall's Second Head of School

The Board of Trustees is pleased to announce the hiring of Mary Kate Blaine as Trinity Hall's second head of school, effective July 1, 2021. Ms. Blaine was hired after a comprehensive sixteen-month national search and will succeed Mary R. Mahon Sciarrillo, founding head of school, who will retire after the current school year. 
"As the founding head, my future will always include Trinity Hall. I have been blessed to be part of Trinity Hall's early chapters and look forward to enjoying the next chapter of my life -- an active retirement with my growing family, including nine grandchildren," shared Mrs. Sciarrillo. "Trinity Hall is poised to enter its next stage of growth, and I share the community's excitement in continuing to build on our strong foundation under Ms. Blaine's leadership."
Ms. Blaine has served as the principal at Georgetown Visitation Preparatory School, an all-girls Catholic high school in Washington, D.C., since 2013. She previously held the role of Chief of Staff to the Superintendent of Catholic Schools for the Archdiocese of New York. Ms. Blaine 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. She 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 & Education.
"Ms. Blaine’s proven commitment to all girls’ education and her experience as an educator, administrator and leader allow her to truly understand Trinity Hall’s mission and vision, and our hopes and dreams for our future," said Board Chair Victoria Gmelich in her letter to the Trinity Hall community.
"It is an honor to accept the privilege of serving as Trinity Hall's next head of school and to continue to build on the school's remarkable foundation of faith and learning and supporting young women who will become leaders the world needs," said Ms. Blaine. "I promise faith and good humor, enthusiasm, hard work, and I know together we will work to ensure the limitless potential of Trinity Hall for generations to come."
The search for Trinity Hall's second head of school was a comprehensive community-wide endeavor conducted over the course of sixteen months with the support of Wickenden Associates, a leading national education-focused executive search firm. The effort was led by Board of Trustees Vice Chair and Head of School Search Committee Chair Miriam Tort, who regularly updated the community during the process. In Fall 2020, finalists visited our campus and were interviewed by faculty, staff, trustees, parents and students. 
Plans for the Trinity Hall community to honor Mrs. Sciarrillo in her final year and to introduce Ms. Blaine as Head of School will be shared in the coming months.
