Tracy Knapp, Farm Manager

Tracy has an extensive farming background in the mountains of southern Appalachia and St. Croix, but she did not always know that she wanted to be a farmer. While earning her BA in Philosophy, she discovered her love of farming while developing curriculum for a local NGO’s Agriculture Academy in Cape Town, South Africa. After graduating, she moved to Delhi, India to learn the arts of grant writing and donor-relations. She spent three seasons growing on an off-grid self-sustained farm in the rainforest in St. Croix. She is excited to join Common Good City Farm and merge her journeys in the non-profit and farming worlds. She can be reached at tracy (at)


Emily Richardson, Operations and Youth Programs Manager

Emily has been interested in agriculture and food issues since she was a kid growing up in rural Maryland. She earned her degree in Environmental Studies from Washington College and then worked for Colchester Farm CSA before moving to DC in 2008. While living in DC, she has worked in the non-profit sector and volunteered with several urban farming projects, including helping to lead field trips at Common Good. After volunteering on the farm, she was excited to join the staff in early 2014. She can be reached at emily (at)


Josephine Chu, Program and Outreach Manager

Josephine Chu manages the distribution of the farm's produce via various outlets including the Farm Stand, CSA, and Small Enterprise. She organizes the Seed-to-Table workshops and Community Events on the farm. As a graduate from American University's MA program in Global Environmental Politics, she became very involved in DC's food justice work. She co-founded Zenful Bites, a social enterprise that provides plant-based eco-catering services and food education programming to foster a sustainable and fair food system in the DC metro region. She joined Common Good City Farm in June 2015 and is thrilled to be able to continue building local and fair food systems.
