Mary Langelier of Lewiston, second from right, chats with Better Homes and Gardens Realtor Lorraine Bennett, right, at the Andy Valley Senior Expo at the Hilton Garden Inn in Auburn on Wednesday morning. Behind them, Realtor Linda Beaulieu speaks with Langelier’s neighbor, Claire Bourgoin. The Realtors were at the expo offering help to seniors, many of whom are in the position to sell their homes, but are uninformed as to how to get through the process. There were dozens of exhibitors helping seniors with everything from health needs to appraising antiques.
