2025-2026 BOARD OF TRUSTEES

All members of the Board are committed to advancing the school’s mission, strategic objectives, and policy positions, ensuring their thorough integration into all aspects of governance and planning. As stewards of the school’s resources, the board bears responsibility for its financial stability and long-term sustainability. Each trustee serves on one or more committees of the board. They  include: Finance, Audit, Investment, Governance, Advancement, Facilities, Retirement and Strategic Planning. Trustees work in close partnership with the head of school and the leadership team to maintain a focus on strategic matters rather than daily operations, thereby cultivating a thriving educational environment.
