A rich heritage. A proud tradition.

W.T. McClellandLike so many Irish immigrants before him, W.T. McClelland saw America as a land where dreams came true, and hard work and perseverance were rewarded. It was simple virtues like these that led W.T. and his wife, Winifred, to start the Shamrock Dairy in Tucson with only 20 cows, a Model T delivery truck and one route man delivering fresh milk to the doorsteps of local customers.

Today, 90 years later, their dream lives on in Shamrock Farms Dairy. As one of the largest family-owned and operated dairies in the U.S., we are a company with a continuing commitment to provide our customers with only the finest products and service.

"My parents had faith that if you treated your employees like family, and your customers like friends, you would succeed. We’re a multimillion-dollar company now, but we're still managed by the same principles."
- Norman McClelland
 CEO, Shamrock Foods

Customer satisfaction is a family tradition.

Thanks to generations of loyal employees and customers, Shamrock Farms has become the successful dairy it is today. And just as we rely on our customers, they can continue to rely on us for superior farm-fresh products and an unconditional guarantee of satisfaction. Our continued commitment to such ideals, and to the community, ensures that Shamrock Farms will remain a proud and respected brand throughout the country.

Our tradition of product excellence begins with our farm-fresh milk. But, naturally, we take equal pride in all our other dairy products, too. Our cottage cheese, fresh sour cream, heavy cream and eggnog have been favorites for years. And thanks to such innovative offerings as convenient On-the-Go Flavored Mmmmilks and Rockin’ Refuel™, we're attracting more and more new customers every day.
