 Wormull took over as manager of Isthmian League Division One South club Crawley Down Gatwick in June 2013. Wormull led the team to the top of the table with five wins and a draw from their first six matches, a performance that earned him the Isthmian South Manager of the Month award for August. They had fallen to sixth by early November, when he resigned his post for what were described as "personal and family reasons".
