California Staff Pictured Above. Not Pictured: Dr. Diana Jerkins and Michael Stein.

People are always surprised by how small our staff is. It's because we create such a huge organic ruckus on the hill, in the field, on the streets, and on the web. Our work for organic farmers goes well beyond a 'day job'. It's a belief in the vision.
