North American Bison sources all of our bison from independent family ranchers like the Rengstorf Family located in Northwest Minnesota. They have been raising bison on their lush grass covered fields for over 32 years. Dale and his wife Beth have made this a family business with the addition of his son-in-law as a partner in their business. By developing environmentally sound processes that support the sustainability of his business and land management, they have been able to ensure the natural resources available for the raising of his herds are retained in their natural state for future generations. The Rengstorf family exemplifies the success one can have by keeping his operation as natural as possible and treating Bison humanely. Learn more about our Rancher Partnerships here.
