The Goodwill thrift store in Bangor will temporarily close between Christmas Day and Feb. 1 so that it can make renovations. The store is adding offices that will allow Goodwill Northern New England to offer job training services in the Bangor location, as well as making other upgrades to the sales floor, according to spokesperson Heather Steeves. Besides operating thrift stores in Maine, New Hampshire and Vermont, Goodwill Northern New England also runs a program called Job Connectio n that pairs participants with a job coach and social worker to help them overcome barriers in their lives to find jobs.
