Our Team works alongside Volunteers, Interns, Board Members, Neighborhood Liaisons and passionate community members to ensure that the protected lands under CKC's stewardship are continuously serving the needs and wants of the local community.


This work falls into three core areas...

Food Production

Ag Education

 Land Stewardship

...and requires an avenue for community participation and input at each level. 

(1)  The Farm Management & Food Production Team was formed in 2019 and consists of professional farmers, volunteers and interns all working side by side to collaboratively care for the farm. They are responsible for taking care of all things related to the soil and crops. Issues, such as, what to plant, how to address soil deficiencies, how to naturally manage pest problem, and who will repair broken equipment, are solved collaboratively.  To join the Farm Management Team contact (PLEASE NOTE: we maintain a waitlist of volunteers and interns for Koiner Farm, but we are trying to start a second farm!)

(2)  The Ag Education Team formed in late 2021 and is composed of professional farm educators, volunteers and advisors from the community. The Farm Education Team is responsible for fulfilling CKC's nonprofit education purpose. They manage the Field Trips Program, the Learning Hubs Program, the Kids'Corner Program and all on-farm and off-farm Workshops, Tours, and Conferences. The Education Team is seeking participation from active/retired/aspiring teachers. If you would like to contribute to the Farm Education Team contact

(3) The Land Stewardship Team consists of East Silver Spring residents, who have come to known as the Neighborhood Liaisons of Koiner Farm. This dynamic team consists of community leaders who hail from diverse backgrounds and poses a strong desire to provide more equitable and functional access to healthy land and food for their community. The work of the Neighborhood Liaisons includes fostering relationships with renters, immigrants, and non-native English speakers, as well as with small local businesses (particularly minority-owned businesses, culturally significant artisans and musicians, and fellow nonprofits). The Neighborhood Liaisons help promote our SNAP/WIC benefits, recruit culturally relevant vendors for our Farm Market, and translate materials to Persian/Dari, Amharic, French and Spanish. To become a Neighborhood Liaison, please contact Hannah at
