The former Leatherhead boss is the new manager at Hemel Hempstead Town.
The club have announced the news after Joe Deeney left his position following a poor second half of the season.
He took over from Dean Brennan in November but the club fell short of expectation and ended the campaign in 16th place.
Now Moore will arrive after guiding Concord into the top seven last term.
The ex-Leyton Orient and Wimbledon midfielder says he can’t wait to get his teeth into his next challenge and will be looking to turn fortunes around at Vauxhall Road.
Moore left the Beachboys last week with former player Danny Scopes taking charge at the Essex club.
