As the largest private landowner in Massachusetts, with properties in 30 towns, the Cowls family is especially synonymous with North Amherst, where it has made its headquarters — and an enduring legacy in lumber and conservation — for 279 years. These days, Cinda Jones, the ninth-generation president of W.D. Cowls Inc., and her team are doing nothing short of creating a new town center in North Amherst. Why? Because the family has always transformed the land into what was most beneficial and needed. Today, she says, that’s a sense of community.
