Leadership
The Discovery School is a non-profit independent school governed by a volunteer Board of Trustees. The Board of Trustees is responsible for ensuring Discovery’s long-term growth and success through setting strategic goals. Governance includes adopting a clear statement of the school's mission, ensuring financial stability, setting policy, and fundraising, according to its established bylaws. The Board has the authority to hire outside counsel and related services as needed.
The Head of School reports directly to the Board and is the only school employee who does so. The Head of School is responsible for implementing the Board’s policies and plans and for the day-to-day management of the school. This includes hiring faculty and staff and overseeing the development of classroom policies and the curriculum. Together, the Board of Trustees and school administration ensure that the concerns, values, and expectations of parents and other constituents are considered in all decisions regarding our culture and who we are, and the quality of education.
