Paige Williams writes: “Andrea Hansen-Miller, a licensed clinical social worker, keeps drop-in hours at her office in Hennepin County (Minn.) Library’s Minneapolis Central Library. To signal that she’s ready to begin, she sets two chairs outside her door, to create a makeshift waiting room, and turns on the lights. A wicker basket holds free hats, shoes, scarves, and gloves, and cabinets and a wardrobe rack are stocked with donated coats. Clients find Hansen-Miller by word of mouth. Her services are not advertised.”
