Crystal Creamery (formerly Foster Farms Dairy) was founded in 1941 by Max and Verda Foster in Modesto, California, a venture following their 1939 founding of Foster Farms. The company claims to be the "largest privately owned dairy in California."
In 2007, Foster Farms acquired Crystal Cream and Butter Company, based in Sacramento, from HP Hood. In 2009, Foster Farms Dairy acquired Humboldt Creamery, based in Fernbridge, California (near Eureka). During 2012–2013, the company re-branded itself as Crystal Creamery.
