Oran Kearney has pledged his future to Coleraine by agreeing a deal keeping him at the Showgrounds until 2015.
The former Linfield midfielder has transformed the Bannsiders' fortunes since he took up the Showgrounds reins just under a year ago.
He has steered the club to a top-four spot in the Carling Premiership this season and into the Irn Bru League Cup final with Crusaders on Saturday week.
Kearney was named Carling manager of the month for December.
Chairman Colin McKendry described Kearney's decision as a "massive boost for the club".
"He has been thoroughly professional in his approach to the job and had a fantastic impression not only on the players but the club in general," said the Coleraine chairman.
"Things are moving in a positive direction and that is largely down to Oran Kearney."
Kearney, who has agreed a three and a half year contract, said: "I am happy to commit to Coleraine. Living locally it is the right thing for me to do and I am privileged to have been given an opportunity to manage at senior level.
"Now when I am trying to attract players to the Showgrounds they can see that I am committed to the long term future of the club."
Kearney, previously in charge at Limavady United, succeeded David Platt in February last year and has lost only seven of the 48 games since he has been in charge.
The Bannsiders are currently on a 12-match unbeaten run.
