A drug testing center so close to Brockton must do brisk business. Must have just moved from the previous Pleasant Street location as signage was non-existent outside and minimal inside. Nevertheless, these guys had same-day availability for a pre-employment drug screen when its Boston and Brookline locations didn’t. Clean facility, cheerful staff, minimal riff-raff among customers. Walk-ins were accepted, but my appointment allowed me to skip to the head of the queue.
