Our Leadership

“College preparation is a means to an end where scholars are equipped to earn a four-year college degree, come back to their community and lead and transform their own neighborhood in the ways that they imagine and the ways that they seek and believe are possible.”

Board of Trustees

The STRIVE Prep Board of Trustees is a group of committed community leaders who support the vision of clearing a path for all families to have access to a high-quality public education in their neighborhood.  Made up of parents, community, business, and foundation leaders, the board helps us maintain accountability to scholars, families and the community by holding public meetings every month to review school progress. Board members also regularly receive feedback from each school’s Family Council, which meets monthly to share parent feedback, organize volunteer efforts, coordinate special events and advise the Board of Trustees. Family Council is comprised of at least seven official members: The principal or a principal designee, at least one teacher who provides instruction at the school, at least four parents or legal guardians of students enrolled in the school, and a community member who does not have children in and is not employed by the school.

Board meeting schedules, agendas and minutes can be found on the Accountability page. To attend a meeting or participate in a conference call, please email Liz Bola, STRIVE Prep Programs Manager, at lbola@striveprep.org.  If you have other questions, please email Board Chair, Crystal Rountree, at Crystal.Rountree@teachforamerica.org .
