Established 1991


Trini Campbell and Tim Mueller

Tim and Trini started farming two acres in Rutherford, CA in 1990. Gradually, after much trial and error, the farm has evolved into a very diverse, year-round farm that relies on a combination of wholesale, retail, farmers markets, and a 1,000-member Community Supported Agriculture program. They employ 50 year-round employees.

Chef Canales says “in the last five years Riverdog has become one of our most important farms. It is hard to say what they don’t do well. While they are a larger sized farm, their produce tastes as though it has been given all the time and attention of a personal garden.


Tractors for transplanting, weed control, and some harvesting.


Challenges include the rising costs of fuel and other essential inputs. Consumer expectation of a low price of produce makes rising costs difficult to absorb. It is always a struggle to continue to offer increasing wages to our employees.


“Farming and access to abundant organic food feeds our souls. We face daily challenges, puzzles and struggles on the farm yet continue to be amazed by the magic of the seed transforming into the food on our tables,” says Trini. “Offering over 100 tomato varieties makes us proud! We also take pride in offering our employees health insurance.”


Implementation of an organic field and crop management program. The fertility program includes the use of compost and amendments such as ocean products.
