Rockdale’s former fire chief, who resigned in June after less than a year in the role, is still in the public service sector, but this time as an instructor at the Rockdale Career Academy. Franklin Wilson applied for the position of public safety instructor at RCA in April when former instructor Matt Mahathey decided to go back to the public safety field, said RCA CEO Miki Edwards. “We are very glad that he has joined our team,” said Edwards.
