"We would just like everyone to understand just how much we love the club and the city," he told the club's website. "There may have been a lot of speculation and a couple of things got held up but they have been ironed out and I am very happy as this is a great place to live and a great place to work.
"I know it is almost impossible for us to match the likes of the Old Firm and Hearts but we can still make good selections.
"There has been a steady improvement in the team and I feel the directors have the drive to take things further and this is important for the management squad.
"We will be working hard to strengthen the squad as you know a couple of the lads could be leaving."
After days of negativity surrounding the club, Aberdeen's director of football, Willie Miller, was glad to get his management trio tied up on new deals.
He said: "We are delighted with the news and we were always confident we would have a positive outcome to the situation.
"Obviously I have the opinion that Jimmy has done an absolutely fantastic job at the club and has brought back stability, and this season in particular we have been extremely successful.
"I am happy with what Jimmy is doing and I have backed him for the last three years and it is great to have the team, all three of them, on board for the foreseeable future."
