We source our milk from approximately 700 dairy farms throughout Wisconsin. Farmers work diligently day in and day out no matter the circumstances. They are vital to the success of our state and we intend to make them proud of the products we deliver.


Continually raising

industry benchmarks

Mullins has complete control of our whey supply from cheese development through the drying process. This ensures quality and consistency throughout the entire process for all of our products. Continuous reinvestment in our facilities with the latest and most efficient technologies keeps Mullins and our product line at the forefront of the industry standards. As a private operation, we are more versatile to work with our customers to customize the product to suit your functional needs.

Our story

Years of continuous growth to Mullins Cheese leads to the install of our first sweet whey condensing plant in 1988. The 1990's and early 2000's are met with more growth opportunities resulting in  the construction of a state-of the-art whey processing facility.

In 2001, Mullins Whey is established when entering the whey protein isolate (WPI) market. Since then, growth through innovation has led us to offer a prominent brand line of dried whey products for the human nutrition and animal feed industries.  Today, we continue to push the envelope of dairy based product offerings.
