MANSFIELD — Despite its size, there are things a neighborhood store can do that a big box store can’t. Knowing the customers — and the customers’ favorites — can go a long way in a business model. For G.M. Thompson and Sons, located at 54 Middle Turnpike in Mansfield Depot, the effort has paid off. The store has longstanding roots in Mansfield’s agricultural community. “It’s important for Mansfield’s history, but it’s also important to have those roots,” George Thompson III said. “It’s what keeps Mansfield, Mansfield.” Thompson said his grandfather, George Merritt Thompson, incorporated the store with his three sons in 1963. Thompson said his dad still works every day, but, now, he and his cousin Bernie are the current owners. The store sells large animal feed, lawn and garden supplies, pet supplies, bird seed, wood pellets and offers a deli section. Two delivery trucks are on the road every day delivering animal feed. The store makes roughly 60 or 70 sandwiches a day, according to Thompson. The family’s impact on Mansfield extends beyond the store. Thompson and his father are members of the Mansfield Fire Department, and the younger Thompson is a mem ber of the town’s economic development commission. “With a family business, you’re more engaged,” Thompson said. “You have a vested interest.” The store is open from 8 a.m. to 5:30 p.m. Monday through Friday and Saturday from 8 a.m. to 3 p.m. More information can be found at gmthompson.net and by call ing 860-429-9377.
