Advancement Team

Hawken's Advancement Team builds and sustains relationships that help our school thrive. Through fundraising, alumni engagement, and external partnerships, we connect people to Hawken's mission, secure resources that support students and programs, and serve as a bridge between the school and key external stakeholders.
