Leadership & Trustees

Leadership and Trustees

Cate is led and governed by people who know and love boarding schools, especially this one.

Many of our administrators and trustees graduated from Cate or other boarding and independent schools while others have children who have been educated here so they’ve seen the impact of a Cate education. We search far and wide for leaders who can make our great school even better and who are devoted to keeping Cate’s enduring spirit fed with new ideas.
