A long tradition
of fresh ideas

W.T. McClelland

Irish immigrant W.T. McClelland saw America as a land where perseverance would be rewarded.
So with nothing more than 20 cows and a Model T delivery truck, he and his wife created
Shamrock Dairy, hand-delivering milk to local customers.

What set them apart was working harder to keep milk fresher, purer and more delicious.

Milking machines are used in Arizona for the first time – and studies
show cows prefer them 3-to-1 over farmers with cold hands.

Shamrock Dairy buys its first refrigerated truck, guaranteeing milk
that’s as delicious and nutritious as it was on the farm.

With the launch of a new plant in Phoenix, Shamrock Dairy starts to offer sour cream, cottage cheese and buttermilk – even more ways to enjoy milk.

Through key acquisitions, Shamrock Dairy becomes the No. 1 dairy in Arizona.
It’s a title we would hold as we continued to grow in the coming decades.

Shamrock Farms is launched – the trusted family farm people love, with exciting new ideas like ice cream, frozen novelties and our spokescow, Roxie.

We were way ahead of all the mobile trends. Long before smartphones, we debuted single-serve mmmmilk in pint and quart sizes.

Shamrock Farms expands into markets outside Arizona, showing the
entire nation what they’d been missing out on.

Shamrock Farms moves its entire 10,000-cow herd to a new state-of-the-art farm in Stanfield, Arizona.

Shamrock Farms becomes the first and only local milk company to offer
organic products to Arizona consumers.

With the opening of a dairy manufacturing facility in Virginia, Shamrock Farms is able to serve its growing national business.

Endlessly entrepreneurial, Shamrock Farms refreshes Rockin’ Protein and
other products with an attention-grabbing new sense of style.
