Plymouth Argyle manager Derek Adams and coaches Paul Wotton, Kevin Nancekivell and Rhys Wilmot have all agreed new contracts with the club.
The 42-year-old has agreed a five-year deal and also becomes head of football.
"The club has made significant strides on and off the field since appointing Derek," chairman James Brent said.
Wotton, who made 491 appearances for Argyle, has been promoted to assistant manager following the departure of Craig Brewster in March.
He has signed a two-year contract along with first-team coach Nancekivell and goalkeeping coach Wilmot.
