Our Business

A State-of-the-Art Cheese and Whey Protein Manufacturing Facility in the Heart of Michigan

MWC is a large-scale cheese and whey protein manufacturing facility in St. Johns, Michigan.

MWC processes over 2.9 billion pounds of milk, and produces in excess of 300 million pounds of superior block cheese and 20 million pounds of value-added whey proteins powders each year. Employing nearly 260 employees, MWC makes world-class products of the highest quality to be sold throughout the world.

This location allows us to partner with regional dairy farmers to receive the freshest milk available for our products. Local milk producers are an invaluable resource to MWC, and are the heart of our business.

Partners in dairy building
a winning business

MWC is a unique joint venture between Glanbia Nutritionals,  Dairy Farmers of America, Inc. (DFA), and Select Milk Producers Inc., The venture is 50 percent owned by Glanbia, with the balance primarily owned by DFA and Select Milk Producers.


Select Milk formed in 1994 out of a desire by a group of family dairy producers to develop a national footprint for the perfect milk. Along with Dairy Farmers of America, Select Milk markets much of the milk produced in Michigan.


Dairy Farmers of America is made up of more than 13,000 diverse family farmers from across the country and, prior to MWC, much of that milk supply was being transported out of state due to lack of local processing capacity.
