Chesterfield's promotion-winning manager John Sheridan has signed a new four-year contract.
The former Leeds midfielder joined the club in 2009 and lead them to the League Two title last season.
Sheridan's assistant manager Tommy Wright and first-team coach Mark Crossley have signed similar deals.
Sheridan told the club's website: "The most important thing about a team is trust and that's what myself, Tommy and Mark all have for each other."
He continued: "We now aim to continue our success into next season, and will be aiming for exactly the same."
Sheridan left Oldham in March 2009 after almost three years in charge at Boundary Park, during which time he took them to a League One play-off semi-final in his first season and narrowly missed out on the top six in his second.
He took over at Chesterfield three months later, replacing Lee Richardson.
