Quinton, who succeeded George Borg at the Queen Elizabeth II Stadium in August 2014, made over 500 appearances for The Iron who parted company with former manager Hakan Hayrettin in April following their relegation from the National League.
Quinton originally joined the Ryman Premier's Towners in December 2013 as a player before becoming Borg's number two. During his three seasons at the helm, he guided the supporter-run club to 7th, 6th and 4th placed finishes and took charge for the last time when his side lost 4-2 at Dulwich Hamlet in the semi-finals of the Ryman Premier play-offs.
Enfield Town chairman Paul Reed paid tribute to Quinton in a statement announcing his departure for the attractive brand of high tempo and attacking football he developed during his tenure and his 56 competitive appearances and five goals as a player.
Reed said: “I would like both personally and on behalf of the club, to thank Brad for all the hard work he has put in since he took over. There have been some very exciting times over the three years he has been in charge and those memories will remain in the minds of supporters.
"His return to a club with which he has such strong connections is, of course, understandable. Brad had already turned down a couple of offers from clubs at a higher level than ours over the last couple of months but Braintree came in with an offer that we just could not compete with."
Calling it the "toughest" decision of his career, an emotional Quinton told supporters: “This has been the toughest decision of my football career. Over the last few days I have had lengthy discussions with my family and we eventually came to the conclusion that a return to my former club at this time was an opportunity that I needed to take.
"I would like to go on record to thank all supporters, including volunteers and directors, from the bottom of my heart for creating something special together. Enfield Town is a fantastic club, which I am sure will go from strength to strength."
Pictured making his managerial debut for Town in a 3-0 win at Hendon in August 2014, he added: "I have to admit I shed a tear after the Dulwich game, as I was totally committed to promotion this time around. I will miss everyone, particularly those who work tirelessly behind the scenes, and hope our paths will cross in the future."
