Coach Dan Herrington is back at Poole Town.
Herrington left his role as Dolphins reserves boss last month due to “irreconcilable differences” with first-team manager Tom Killick.
Fellow coach Paul Turner, who worked alongside Herrington last season, has stepped up to take his job with under-18s boss Lee Middleton moving up to serve as assistant to Turner.
And now Herrington has returned to the club, filling the vacancy left by Middleton in the under-18s.
A club statement read: “Following meetings between senior and youth committee members, the club are delighted to announce that Dan will be running the under-18 team next season.”
