Gallagher has acted following the recent challenges being faced by the first-team, by bringing in Brooks, who will take up the role of assistant-manager.
Brooks was highly recommended to Gallagher and the club by current Norwich City first-team coach and ex-Trawlerboy, Gary Holt, who had Brooks as his sidekick at Falkirk.
Throughout his coaching career Brooks has held the positions of first-team assistant-manager, first-team coach, caretaker-manager, reserve team manager, youth team manager and director of the centre of excellence in the Premier League and Leagues One and Two.
Having recently been involved in management and coaching roles at Falkirk, Cambridge United and most recently Southend United, Brooks will bring a wealth of knowledge, experience and support to Gallagher and the club.
