New Gwinnett County Commission Chairwoman Charlotte Nash took office Monday, vowing to honor the trust of those who elected her.

“This is an important time in Gwinnett County’s history,” Nash told more than 300 people who watched her take the oath of office at the Gwinnett Justice and Administration Center. “I pledge to each of you that I’m going to do the right thing for Gwinnett County.”

Nash won a four-way race for commission chairman on March 15. She will fill the unexpired term of former Chairman Charles Bannister, who resigned in October.
