"I am truly thankful to the citizens of Rocky Mount, the city administration, and the men and women of the Rocky Mount Fire Department for giving me the opportunity to do a job I have completely enjoyed every day for 29 years," Mercer said. "I have had the pleasure of being a public servant in one of the best communities there is."
