Meet the Team

Who We are

The Common Acre came together when artists and urban farmers decided in 2012 to work together on a shared mission of maximum social impact.

Since our inception, our team has grown to encompass doctors of medicine and science, city planners, educators, and strategists, and a great crew of multi-talented volunteers.
