Career
Hessey is currently employed as the manager of Marine. During a career which spanned eighteen years, Hessey played for Liverpool F.C Leeds United, Wigan Athletic, Huddersfield Town, Kilmarnock, Blackpool, Chester City and Macclesfield Town. Hessey joined Chester after the club were promoted back to the Football League in 2004 and was a first-choice player for much of his first three years at the club, although he quite often missed games because of injury and suspension problems.
The most notable was a five-match ban at the start of the 2006-2007 season after an incident in the home game against Stockport County the previous season.
Hessey has proved to be a versatile player, operating in both central defensive and full back roles and also in a holding midfield spot. Chester manager Bobby Williamson, who managed Hessey at Kilmarnock, placed him on the transfer window in the summer of 2007.
He did not figure in the Chester 16-man matchday squad in any game for the 2007-2008 season and was allowed to join League Two rivals Macclesfield Town on 10 November 2007 in a two-month loan. In January 2008, this was extended until the end of the season. and at the end of the season he was released by Chester.
Hessey followed up his successful loan period by signing a two-year contract with Macclesfield.
He was released by the club, along with 10 other players at the end of the 2009/10 season. He joined Accrington Stanley in August 2010 on a twelve-month contract after having been on trial at the club On 14 May 2012 it was announced Hessey had left Stanley after failing to agree a new contract.
He spent the 2012-2013 season with Barrow AFC in the Conference National, but left at the end of the season after the club were relegated.
He moved to Prestatyn Town of the Welsh Premier Division for the start of the 2013-2014 season. Shortly after he joined Marine on loan (initially until January) and made his debut on 30 August 2014 in a 2-1 defeat at home to Buxton.
This loan deal was extended, and Hessey subsequently became caretaker manager following the departure of Carl Macauley. An excellent run of form saw Hessey secure the managerial post with 2 games left in the season.
The change in form under Sean"s leadership saw Marine maintain their place in the Northern Premier League Premier Division for the 2015/16 season.
