Melvin has been dairying since 1981 on the farm started by his father. In 2007, Melvin and his wife, Kelley, started Medeiros Holsteins to diversify their operations and capitalize on the opportunity to market milk through DFA. All three of Melvin’s sons work on the 1,400-cow dairy, with his two oldest also owning their own dairies. The operation also functions as a market for its purebred Holstein genetics. Melvin’s youngest son manages the 550 acres of double-crop wheat and corn to supply all the dairy’s silage needs. Melvin serves on the Membership and Quality Committee for DFA’s Western Area Council, the Cattlemen’s Beef Board and the California Cares and Environmental Justice Fund Committee.
