St. Onge grew up in Connecticut and later in Colorado . At the beginning he also competed in the mogul slope division, only from 2000 did he focus entirely on the aerials discipline. He made his debut in the World Cup on January 22, 1999 in Heavenly , where he finished 13th. He only played part of the next three seasons for school reasons. In 2003 he took part in the world championships for the first time.
St. Onge rose to the top of the world in the 2004/05 season. After a few top 10 results in the previous winters, he won his first World Cup competition on January 9, 2005 at Mont Tremblant , followed by another victory in Deer Valley three weeks later . At the 2005 World Cup , he jumped to sixth place. The 2005/06 season was similarly successful with two World Cup victories.
