Tonbridge were relegated from Skrill South at the end of the season.
Steve joined the club at the beginning of the Paul Doswell era, initially as player-coach, and made over 100 first team appearances, the last of which was against Molesey in the Surrey Senior Cup in February 2013.
Manager Paul Doswell also added his good wishes. ''I'd like to congratulate Steve on getting the job at Tonbridge. He's been a fantastic colleague and clubman over the past six years and I've seen him grow as a person and a coach, and no-one deserves the chance more. It's something we've been discussing for a year or so now, and we gave Tonbridge a very strong recommendation that they choose him. He goes very much with our good wishes, and I'd like personally to wish him all the best in his future career.''
