Welcome from the Head of School

MS. JENNIFER CICCARELLI

HEAD OF MARLBOROUGH SCHOOL

As Marlborough’s ninth Head of School, Jennifer Ciccarelli leads with clarity, purpose, and an unwavering belief in the power of girls’ education. She is committed to creating the conditions in which Learning Sparks Purpose—and where every student feels seen, heard, and empowered to lead.

A lifelong advocate for young women, Jennifer has spent her entire career in all-girls schools in leadership and teaching roles. Before joining Marlborough, she served as Head of Columbus School for Girls (CSG), where she launched a pioneering preschool–12th Grade computer science program designed to create a strong pipeline for young women entering STEM fields. She also founded a leadership center focused on equity and social responsibility. Prior to CSG, she was the Middle School Director and Assistant Head of the Winsor School in Boston, and she also held key positions at The Girls' Middle School in California and Greenwich Academy in Connecticut.

Her leadership is marked by vision and impact—from strengthening academic programs to inspiring record-breaking philanthropy. She’s also a mentor to rising school leaders and an active voice in national conversations about girls’ education, serving on the boards of the Heads Network and the International Coalition of Girls' Schools.

Jennifer lives in Los Angeles with her family and is energized every day by the brilliance and ambition of Marlborough students.
