DeMont was born in San Francisco, California, and he attended Terra Linda High School in suburban San Rafael, California.
DeMont is often remembered for the controversy arising from his disqualification at the 1972 Summer Olympics because he tested positive for a prohibited substance present in his prescription asthma medication. He trained with the Marin Aquatic Club. As a 16-year-old, DeMont qualified to represent the United States at the 1972 Summer Olympics in Munich, Germany.
Following the race, the International Olympic Committee (International Olympic Committee) stripped DeMont of his gold medal after his post-race urinalysis tested positive for traces of the banned substance ephedrine contained in his prescription asthma medication.
The positive test following the 400-meter freestyle final also deprived him of a chance at multiple medals, as he was not permitted to swim in any other events at the 1972 Olympics, including the 1,500-meter freestyle for which he was the then-current world record-holder. Before the Olympics, DeMont had properly declared his asthma medications on his medical disclosure forms, but the United States. Olympic Committee (USOC) had not cleared them with the International Olympic Committee"s medical committee.
At 1973 World Aquatics Championships in Belgrade, Yugoslavia, DeMont became the first man to swim the 400-meter freestyle in under four minutes (3:5818). In 2001 the USOC admitted that it had mishandled DeMont"s medical information at the 1972 Olympics and appealed to the International Olympic Committee to reinstate the medal.
To date, the International Olympic Committee has not officially changed the race results nor overturned his ban.
DeMont was an assistant coach for the South African men"s swim team at the 2004 Summer Olympics in Athens, Greece, and the 2008 Summer Olympics in Beijing, China.
In 2014, after being a member of the coaching staff for 24 seasons, DeMont was named the head coach of the Arizona Wildcats men"s and women"s swimming and diving teams at the University of Arizona.
