Initially drafted to the NHL by the New York Islanders third overall in the 1996 NHL Entry Draft, Jean-Pierre (usually referred to as J.P.) never succeeded in reaching a contract agreement with the Isles, which resulted in him being traded to the Chicago Blackhawks in 1998. Two years later, along with Doug Gilmour, he was traded to the Sabres for Michal Grosek, for whom he played excellently, especially during the Sabres' 2006 playoffs run, where he scored an overtime goal in Game 3 second round series versus the Ottawa Senators. He served as the Sabres' captain briefly in January 2004.
In August 2006, Dumont signed a two years deal with the Nashville Predators after the Sabres rejected Dumont's $2.9 million arbitration award.
