Trumbull-Nelson was founded in 1917 as the W.H. Trumbull Company. In the early years, our founders built fine homes in Hanover and the Upper Valley area. Word of mouth spread about their quality craftsmanship. From there the firm grew to become one of the region’s largest construction companies over the last 11 decades. We at Trumbull-Nelson are proud of our heritage, having built indelible landmarks throughout many neighborhoods and commercial districts throughout New Hampshire and Vermont.
