Initially engaged as a consultant for club development with the remit of revamping the youth system and creating a community wing, Warren is now chief executive here at Cappielow as well as a club director.
Co-opted as a member of our board on 1 October 2015 before his appointment as CEO on 9 January 2017, the Englishman has transitioned from representing the club on the playing field to making his presence felt in the boardroom.
The former striker started his playing career with boyhood heroes Sunderland and fulfilled a childhood dream by appearing in the 1992 FA Cup final.
After leaving the Black Cats, he had short spells with Raith Rovers and Scarborough before settling with Berwick Rangers, from whom we signed Warren for £100,000 in 1995.
A distinguished nine-year Cappielow career, in which Warren scored 53 goals in 247 appearances over two separate spells to firmly establish himself as a fan favourite, followed.
Since hanging up his boots in 2005, the father of three has worked within the game for PFA Scotland and Opta.
Perhaps his proudest moment, though, was watching son Lewis follow in his footsteps by scoring at Cappielow.
