Justin works closely with his team which includes the City Harvest initiative, to support community and cooperative gardens throughout Philadelphia for a successful growing season. Justin received his B.A. in International Affairs and Socio-cultural Anthropology from the George Washington University, and received his Nonprofit Executive Leadership Certificate through Bryn Mawr College. Justin has spent the last 15 years focusing on equitable and sustainable food systems locally and internationally with a focus on Central America.
