We are delighted to announce that the Board of Trustees has appointed Cecily Stock as our Interim Head of School for the 2025-2026 academic year. With graduate degrees in psychology and law, and over 25 years of transformative leadership in independent schools, Cecily excels in mission-driven strategic planning, and guiding institutions through periods of growth and development. During her tenure at San Domenico School (K to 12th grade), Cecily served in multiple roles including school counselor, learning specialist and middle school division head. As head of school, Cecily led San Domenico through significant changes and championed bold initiatives, skillfully transitioning it from a 173-year-old Catholic institution, to a thriving, values-based independent school while preserving its core values of study, reflection, community, and service. Her leadership struck a delicate balance between honoring the school’s history and evolving to meet contemporary needs, achieving long-term financial stability, and revitalizing enrollment.

Cecily’s success in modernizing school models and launching pioneering programs such as an integrated STEAM program, a Purpose-Learning Curriculum, the Game Design Academy, a Contemporary Music Program, and a Department of Philosophy, Ethics, and World Religions, has solidified her reputation as an educational visionary. Cecily is also credited with strengthening faculty and staff development and promoting a “growth mindset” culture. She championed professional development focused on fostering a culture of belonging and inclusion, as well as technology integration, ensuring that teachers had the tools to support “the whole child” in a rapidly changing world. She is renowned for her mentorship and team development skills, coaching future leaders, and fostering a collaborative environment. 

We are confident that Cecily is the ideal leader for TPS at this pivotal time, given her expertise, passion for our values-driven mission, and the launch of our 2025 strategic plan. Guided by our mission as a “North Star,” Cecily will bring both fresh perspectives and strategic insights. Her extensive experience will be crucial as she collaborates with both our TPS and broader community to maintain our school’s considerable momentum, and work in alignment towards our common goals. In her role as interim head of school, Cecily will focus on setting up our school for success during the transition period, preparing the foundation for the long-term head of school. Cecily has three adult children, all graduates of independent schools, and plans to relocate to Sonoma with her husband and two cats for the 2025-2026 academic school year.
