Our Leadership

The GJA community is led by an esteemed and committed Board of Trustees and Head of School Ramón Javier.


Ramón brings to us nearly two decades of leadership experience at some of the most pre-eminent independent schools and educational access programs in New York City. Since 2016 he has been Director of Equity and Inclusion at Trinity School, where he acted as the senior administrator responsible for creating an inclusive environment grounded in academic rigor and equitable practices, while working closely with the Board of Trustees. Prior to Trinity, Ramón was Director of Diversity and Equity at Packer Collegiate Institute in Brooklyn from 2012-2016. 


A graduate of Williams College, Ramón earned a Masters of Education (Ed.M.) and M.A. in Psychological Counseling from Teachers College, Columbia University, and served as one of two founding mental health counselors at KIPP NYC College Prep from 2009-2012. Before that he worked at The TEAK Fellowship and Prep for Prep, both of which are premier education access programs that help to prepare underserved, high achieving students for acceptance to, and success in, the nation’s most select secondary schools and colleges. 


As a native New Yorker and Prep for Prep alumnus himself, Ramón comes to GJA with an intimate knowledge of the enormous potential of middle school boys as well as a deep understanding of their needs and the challenges they and their families face.

Ramón Javier 


Head of School, GJA 

GJA gave me a great foundation of self. They taught me that I belong no matter what. In a room of 60 or 600 people, I belong.
