When the company was founded in 1922 it was known as Shamrock Dairy. Shamrock Dairy began in Tucson with only 20 cows and a Model T delivery truck. The processing plant for the dairy products is actually located in Phoenix. In 2003 Shamrock moved the farm to Stanfield, Arizona. Stanfield is in Pinal County, west of Casa Grande. Students from Stanfield Elementary School were the first to take an official school tour of the farm.
This time line provides an amazing and humorous snapshot of the history of Shamrock Foods.
Roxie told me this, and she said I can tell you: The property in Stanfield purchased by Shamrock Farms is actually quite a bit bigger than 240 acres, and will be used for future growth.
