Koopman Lumber’s story began with a simple act of neighborly kindness. In 1939, New England builder Peter Koopman offered surplus building supplies from his garage in Whitinsville, Mass., just steps from what would become the company’s first store. From these humble beginnings, Koopman Lumber has grown into a family-run enterprise with 12 locations and more than 400 employees, serving professional contractors and homeowners across the central and eastern region of Massachusetts.
Today, the third generation of the Koopman family—Dirk Koopman, his sister Denise Brookhouse, and her husband Tony Brookhouse—leads the company with the same community-driven ethos that Peter Koopman established decades ago. Their success, particularly at the Beacon Award-winning Dennis, Mass., location, highlights Koopman Lumber’s commitment to customer service, innovation, and local involvement. With a focus on professional contractors and a deep connection to the community, Koopman Lumber continues to grow and thrive.
Koopman Lumber has been an LMC Dealer since 1984
