Joining the Brooklyn Prospect team in 2009, Ms. Prince has been honored to serve as a member of the founding team of the original middle school, as well as the Prospect Schools CMO.

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.
