Cannell will officially take over Oct. 14. In the meantime, she will remain Orange County's economic development assistant, her position for the past five years.
"The main difference between this new job and my old job is having an allegiance to chamber members," Cannell said. "But being an economic development assistant first is a good lead to being president of the Chamber of Commerce."
County Manager John Link said he approves of Cannell's appointment.
"She has already done an outstanding job with the economic development program throughout the county," he said. "She has the enthusiasm, experience and energy needed."
County commissioners also said they are pleased with the board of directors' decision to choose Cannell.
"I am very happy for her and glad that we've got someone with her confidence," said chairman Barry Jacobs.
Commissioner Moses Carey said Cannell was the most qualified candidate.
"She will give the chamber a shot in the arm," he said. "She is the best person to carry out the activities of the chamber."
Cannell, originally from Maners, said she will be a great person for the job because she has enthusiasm and excitement about working with business people of Orange County and promoting membership businesses.
