 where we started…


Larry and Margaret DeHaan both come from a long history of dairy farming. They were married in 1975 in Southern California. After a few months, they purchased 120 cows and started their own business. Through the years of hard work and many blessings, they gradually expanded and made a few moves around the area. In 2004, they sold the dairy in California and moved to Colorado. They purchased Front Range Dairy and became partners with their son David, who has expanded the dairy to what it is today.
