Knoxville Chamber of Commerce Executive Director Aanna Hoch will be stepping down as Chamber Director. Hoch told the Chamber board Wednesday that her husband was offered a position with a construction firm in Des Moines, and the obligations require the family to move to Des Moines. Hoch says that she will stay on as long as it takes to find the best person to lead the Chamber in the future. Chamber Board President Todd Chambers says Hoch they will begin the search for a new director by the beginning of next week.
