California Dairies, Inc. is the number one dairy cooperative in the number one dairy state in the United States. California Dairies, Inc. is the result of a successful 1999 merger of three of California's most financially successful cooperatives; California Milk Producers, Danish Creamery and San Joaquin Valley Dairymen. All three cooperatives were rich in tradition and established their roots back near the turn of the 20th century.
