Board Members

The role of the School Board of Trustees is to set policy and focus on long-range and strategic issues. GSES is proud to boast an active Board of Trustees, who actively support and promote our school’s mission, vision, strategic goals, and policy positions. The Board is currently made up of 12 individuals, with representation from local community leaders (both private business and independent education), the Parent Association, Alumni, the Church of the Good Shepherd, and the Head of School. If you know of someone whom would make a great addition to our Board, please contact Heather Vaughn at 561-746-5507.
