Quinn began his career at Crystal Palace, where he came through their youth ranks.
His hard work at youth level was recognised by then Crystal Palace manager Dave Bassett, who promoted Quinn to the first team squad which led to him making his debut with fellow youth team mate Danny Boxall on the last game of the season at home against Norwich City in 1996.
Palace were through to the play-off final at Wembley, due to players still being on the injury list Quinn was again picked to start against Leicester City. Palace lost and were forced to carry on in the First Division for the 1996-1997 season, where under Dave Bassett, Quinn was a regular in the team making 28 appearances and scoring two goals.
Later on that season Bassett left and Steve Coppell was brought in, with Quinn falling down the pecking order. Quinn made his first and only appearance in the Premier League on 27 September 1997 in a home match against Bolton, coming on as a substitute after 72 minutes for Kevin Muscat.
After spells with Brentford, Oxford United, Bristol Rovers and several non-league clubs (most recently AFC Wimbledon and Welling United) he signed with Cray Wanderers for their inaugural season in the Isthmian Premier League for 2009-2010.
Quinn joined Kent League side Sevenoaks as a player-coach for the 2010-2011 season.
