Keiron Cunningham has extended his contract to remain as head coach at Saints until the end of 2018.
It follows a successful first year in charge at his hometown club.
Chairman Eamonn McManus said: “Keiron is a young, talented and ambitious British coach who, even at the very beginning of his career, has already won the absolute respect of his team and of all at his club.
“In his first season he took the team to within a whisker of another Grand Final and against the background of an injury ravaged campaign.
“He will continue to gain experience, as will his young side.
“No one knows the Club, and its standards and its expectations, better than Keiron.
“The extension of his contract will bring stability to the club and enable him to implement longer term plans and strategy in addition to seeking immediate success.”
Cunningham added: “I really enjoyed my first year as head coach at the club and
I am looking forward to the future with this great group of players.
“It is an honour to coach my hometown club and we are well positioned for success in the coming seasons.
“I'd like to thank Eamonn, Mike Coleman, Mike Rush and the board for agreeing to extend my deal; they have been steadfast in their support for me.”
