Gary joined Galway United in 2010 from local side Galway Hibernians, and made 2 league appearances in his debut season at Terryland Park. In 2011 Gary cemented a place in Galway's first team under Sean Connor and made 28 league appearances in what was a traumatic year for the Tribesmen. Galway finished bottom of the Premier League with just one league win all season. It would prove to be the club's last as the board declined to apply for a licence for the 2011 season.

In January 2012 it was announced that Gary would join Johnny Glynn at Mervue United.
