Milk Source LLC was co-founded in 1994 by Jim Ostrom, John Vosters and Todd Willer — all from multi-generational Wisconsin farm families — and traces its roots back to 1965 when a small 30-cow dairy farm was started in Freedom by John’s parents. Milk Source operates quality dairies in Wisconsin and throughout the greater Midwest, producing milk to be used for cheese, butter and other dairy products. Milk Source also has a calf farm and a heifer raising facility, all featuring modern, sustainable and environmentally sound farming practices. Milk Source's goal every day is to be an outstanding dairy producer through quality care of animals, sustainable practices, environmental accountability and constant attention to detail. We are proud of an honest and considerate work force, and have earned a reputation as an outstanding place to work.
