Starting with just 20 cows and a Model T delivery truck in Arizona, Shamrock Dairy (now Shamrock Farms) now is a multimillion-dollar company with more than 10,000 cows and nationwide distribution. Although it’s come a long way in nearly 100 years, the company has stayed true to its roots.
The company began in 1922 with Irish immigrant W.T. McClelland and his wife hand-delivering milk to local customers. Their goal was to deliver fresh, pure and delicious milk, according to its website. Over the years, Shamrock Farms invested in milking machines, refrigerated trucks, state-of-the-art facilities and new products, but maintained its entrepreneurial spirit.
