River Oak Orchards farming roots go back four generations in the San Joaquin Valley. In 2008, River Oak Orchards vertically integrated its walnut farming by building a walnut processing facility. River Oak started with an in-shell only facility to tap into the global demand for in-shell walnuts. Year after year, River Oak continues to increase the amount of walnuts we process. In 2016 River Oak expanded its operation to include a state of the art kernel processing facility. This facility includes the newest technology for sorting and shelling equipment.
