The 41-year old stepped down in May 2022 before taking over at Buxton last summer.
But the move didn’t go to plan and he finds himself back at Victory Park in a very different role.
Helping manager Andy Preece from the directors’ box he wants to help push the club on and off the pitch after four years on the touchline.
Vermiglio won 61 of his 165 games in charge between 2018 and 2022.
He also took the club on a record-breaking run in the FA Cup, which eventually came to an end at the hands of Premier League Wolves.
He spoke of his pride at steering the club forward in a very different role than before.
He said: “It is a privilege and an honour to have the opportunity to serve Chorley Football Club as chairman.
“I am excited to work with the new owners and Andy to build on the good work of Ken and Graham.
“I look forward to playing a part in the development of the club, while helping to preserve its values and heritage.”
