Hillary Prince

Chief Financial & Growth Officer


Hillary Prince is the Chief Financial Officer of Prospect Schools.

Joining the Brooklyn Prospect team in 2009, Hillary has been honored to serve as a member of the founding team of the original middle school, as well as the Prospect Schools charter management organization. Leading both finance and operations for many years, she developed scalable systems and established the school’s strong early operational reputation, built a foundation of strong fiscal health for the organization, and has led several building projects and new school launches. Since taking on the role of Chief Financial Officer in 2018, Hillary has narrowed her focus to finance and is now responsible for managing a budget which, under her stewardship, has grown from $2 million to greater than $35 million. Additional core responsibilities include business operations, real estate, and capital projects, and long-term strategic planning.

Prior to building a career in K-12 education, Ms. Prince developed leadership skills and gained operational experience through her work in event management with Madison Square Garden. Deciding to follow a long-held interest in education – and in particular, in school integration, herself attending an urban magnet high school – Hillary completed a yearlong graduate internship at a globally-focused International Baccalaureate magnet school in CT before moving to Brooklyn in 2006. She went on to hone and apply her operational skills to the educational space, holding several roles with The Princeton Review, including Regional Director of Operations, where responsibilities included leading the implementation and national expansion of federally funded afterschool programming.

Ms. Prince earned a B.A. in English-Literature from Skidmore College, and an M.S. in Language Arts Education from the University of New Haven, and is currently enrolled in a nonprofit leadership certificate program at Harvard’s Kennedy School. Hillary left NYC in 2016 to build a home in the Hudson Valley with her husband and two young children.
