Knoxville Chamber of Commerce Board of Directors President Mikol Sesker tells KNIA KRLS News that Executive Director Larissa Van Donselaar has submitted her resignation, with a final day of June 27. Van Donselaar has served as Chamber Director for three years. Sesker says due to the time constraints involved in the growth and successes of the past three years, Van Donselaar stated her desire to spend more time with her family as a reason for resigning. A committee has been formed, and the search for a new Executive Director will begin in the next several days. In the interim, current staff and board members will handle day to day operations.
