JSJohn Sullivan

Director of Teacher and Student Development

Mr. Sullivan grew up on the beaches of Central New Jersey (no he did not go to high school with any cast members of the Jersey Shore). He has recently moved back to the NYC area after five years of teaching at a charter school in Massachusetts. Prior to that, he was a founding teacher at the Williamsburg Charter High School. In his free time, he enjoys going on day trips and adventures with his wife and two sons. He enjoys hiking, snowshoeing and having a healthy obsession with meteorology. Urban planning, architecture, street design, and neighborhood observations fill the rest of what little time he has left each day. As a huge believer in what communities can accomplish, cooperation and compassion, he is very excited to be a part of a team that displays so much of both!
