He told the club's official website: "I've been delighted by the way Gary has reorganised the club from top to bottom and I'm delighted with the way he has forged a successful working relationship with Keith Millen.
"It's great that both have committed to the football club and now we can look forward to moving things forward to even bigger and better things.
"It should be evident to everybody that the management and board works well together and our focus has been on stability.
"We aim to establish ourselves in the Championship and push on to whatever we may achieve."
