Board of Trustees

Governance of the school starts with the board of trustees, whose function is to advance Galloway's mission and objectives by developing policies and long-range plans to assure the well-being of the school; ensuring the long-term financial viability of the school; and hiring and working collaboratively with the head of school, who is in charge of day-to-day administration and operations.

School leadership must be forward-thinking. To sustain the school and its mission, the board identifies and studies issues and challenges that will impact the school, then forms policies to address those issues. This is accomplished through a system of standing committees, as well as strategic committees and task forces, which focus on specific areas of interest and governance designed to enhance the Galloway experience.

The Galloway School's board of trustees is composed of dedicated and hardworking volunteer members with varied skills and perspectives. Trustees are parents of current and former students, alumni, and members of the external Atlanta community. All share a deep personal commitment to the school and its future. Board members normally serve three-year terms and are eligible to serve up to two consecutive terms.
