While attending Claremont Men's College, he was an outstanding athlete, serving as captain of the golf team and all-conference guard on the basketball team. Biszantz graduated with a degree in business administration in 1956 and went to work for his father's auto dealership. In 1969 he founded his own dealership, El Rancho Ford, and ran it successfully until the mid-eighties, when he sold it to focus on the expansion of Cobra Golf, a small golf club manufacturing company which he co-owned.
