Career
Collins began his youth career as a scholar at Watford, signing a professional contract with the club in June 2004. However, he failed to impress and was released the following February. Collins joined Havant & Waterlooville F.C. for the rest of the season, quickly impressing the fans and signing a full contract with the club in May 2005.
Collins went on to play four seasons with The Hawks, becoming a first team regular and being rewarded with the captaincy for the 2007-2008 season.
In January 2011 Holdsworth became manager of League Two side Aldershot Town, and Collins followed his former boss five months later, signing on a free transfer at the end of the 2010-2011 season. On January transfer window deadline day on 31 January 2012, Collins signed for Forest Green Rovers on an 18-month contract for an undisclosed fee.
In July 2012, Collins signed an extension to his contract at Forest Green which would see him stay at The New Lawn until the end of the 2013-2014 season. In May 2013, Collins and Forest Green agreed to the mutual termination of his contract and he moved to Eastleigh.
Before signing a professional contract with Aldershot, Collins worked as a primary school teacher.
He has also worked as a football coach, and received an FA level 3 coaching badge during his time at Watford.
