The two clubs have agreed an undisclosed fee for the defender.
Dean has featured 163 times for the Ravens and was one of former manager Tommy Brookbanks first signings.
He played a massive role in getting the club promoted to step 3 and quickly became a fans favourite.
Chairman Glyn Rennocks commented 'I have nothing but respect for Dean and he’s been a pleasure to have around the club as well as being a very good player. I’m glad he can go and get regular football again and thank him for his efforts at Coalville.’
Everyone at Coalville Town would like to wish Dean all the best and hope to see him down the MCSS in the near future.
Good luck, Deano!
