Beauprez was born in Lafayette, Colorado. He grew up on his family's dairy farm, which had been purchased by his grandparents, outside of Boulder, Colorado. He is the son of Marie (née Stengel) and Joseph C. Beauprez. His paternal grandparents had emigrated from Belgium to Colorado and raised draft horses on the family's land. His mother's family was of German descent. His parents raised both Hereford and dairy cattle on the farm. Beauprez often cites his father's example as a major influence on his life.
