The Leffell Difference Few Jewish day schools combine the scale, reputation, resources, and community impact of The Leffell School. For generations, Leffell has served as both an educational institution and a central pillar of Jewish life in Westchester County and the greater New York metropolitan area. Leffell occupies a unique place within Jewish education. As an independent Jewish day school, it brings together families from across the Jewish spectrum in a community rooted in Jewish learning, values, and peoplehood. Students learn alongside peers with diverse backgrounds, perspectives, and practices, developing both a strong sense of Jewish identity and an appreciation for the richness and diversity of contemporary Jewish life. The school’s influence extends well beyond its campuses. Leffell graduates can be found in leading universities, professions, Jewish organizations, and communities throughout the United States, Israel, and beyond. A loyal, generous, and multigenerational network of alumni, parents, grandparents, trustees, and supporters remains deeply invested in the school’s future and its mission of educating the next generation of Jewish leaders, thinkers, and citizens. The Search The Leffell School enters this search from a position of considerable strength. The school benefits from strong enrollment, a healthy balance sheet, a substantial endowment, and a deeply committed philanthropic community, with annual fundraising expected to exceed $4 million next year. Supported by a dedicated Board of Trustees and talented leadership team, the school has the resources and institutional capacity to pursue ambitious goals and invest meaningfully in its future. The coming years present exciting opportunities for continued growth and innovation. The school is advancing a significant renovation of its Lower School campus, investing in its academic and co‑curricular programs, and continuing to strengthen its position as a leading destination for families seeking an exceptional Jewish and secular education as well as a meaningful community experience. These efforts build upon a long tradition of excellence while ensuring that the school remains responsive to the evolving needs of students, families, and the broader Jewish community. The Opportunity The Leffell School seeks a visionary and relationship‑driven leader to build upon an extraordinary foundation and help shape the next chapter of its growth. Reporting to the Board of Trustees, the Head of School provides overall leadership for the institution and is responsible for advancing its mission, educational vision, and strategic priorities. The Head oversees all aspects of school life, including academics, Jewish life, enrollment, fundraising, finance, operations, and community engagement. This is an outstanding opportunity for an accomplished leader to partner with a talented and dedicated team of educators, administrators, trustees, parents, and alumni who are deeply invested in the school’s success. The next Head of School will have the opportunity to articulate a compelling vision for the future, strengthen an already distinguished institution, and help ensure Leffell continues to thrive amid a changing educational and communal landscape. Stakeholders expressed a desire for a leader who can build on the school’s many strengths while thoughtfully addressing important opportunities related to enrollment growth, affordability and accessibility, faculty and staff support, academic excellence, and the continued innovation and evolution of the student experience. Equally important will be preserving the warmth, relationships, and sense of community that have long distinguished The Leffell School. The next Head of School will serve as the chief ambassador for The Leffell School, building meaningful relationships with students, families, faculty, alumni, trustees, donors, and the broader Jewish community while advancing the school’s mission and strengthening its reputation as one of the nation’s leading Jewish day schools.
