Since losing the ability to offer health care insurance, chambers of commerce in Vermont have seen more financial strain due to losing members who had joined solely for the coverage. At the same time, chambers have had a renewed focus on strengthening other programs — and trying new ones — which add value for local businesses. That value is even more important now, given key changes at two local chambers. Recently, the Manchester and the Mountains Chamber of Commerce announced it was closing, only to announce its reopening days later. Manchester chamber officials and local partners are taking a hard look at the organization’s future, and efforts are underway to get the chamber on firm financial footing.
