Riverdog Farm

Trini Campbell, Tim Mueller

Tim Mueller and Trini Campbell started farming in 1991 in Napa County. They rented two acres and sharecropped a small, mixed fruit orchard. In 1996, they moved to the Capay Valley in Yolo County, where the hot summer months and frosty winters enhance crop flavor.

Dedicated employees keep the farm running smoothly and ensure exceptional crop quality. Customers love their carrots, greens bunches, and eggs, as well as their tomatoes, peppers, and melons in the summer. Riverdog recently diversified into chicken production.

Each year is different, and Tim and Trini learn as they go. They have been selling at the Berkeley Farmers’ Markets since their beginning. Riverdog’s reliable customer base in Berkeley has contributed greatly to the farm’s success.
