Gaylea Prichard-Silvers


Gaylea’s interest in education began when she led school and community groups on adventure courses for Princeton University’s outdoor education center. Her belief in the value of experiential education deepened when she worked with student and community groups as a Peace Corps volunteer in Côte d’Ivoire. As a science teacher in public and private schools in New York City (including Brooklyn International High School), the District of Columbia, Virginia, Ohio, and Angola she focused on project-based instruction.

Gaylea has a B.A. in Biology from the University of Kansas and an M.A. in Science Education from Teachers College Columbia University. She received her principal credential through the New York City Leadership Academy’s Aspiring Principals Program and completed a residency at Flushing International High School.
