Koopman Lumber Announces CEO Transition as Third Generation Takes the Helm

Koopman Lumber will enter 2026 with a significant leadership transition, as the family-owned company prepares to shift its top executive role to the next generation. Beginning January 1, Denise (Koopman) Brookhouse will become chief executive officer, succeeding outgoing CEO Dirk Koopman, who has led the company since 2010.

Dirk will move into a newly created role as president, where he will support long-term strategy and help guide the company’s continued growth. Chief Operating Officer Tony Brookhouse will remain in his position. The transition reflects the company’s long-standing focus on stability, values-driven leadership, and a multigenerational approach to stewardship.

Founded in 1939, Koopman Lumber has grown from a single retail store in Central Massachusetts to 17 locations across Massachusetts and Connecticut, including the recently acquired Lyon & Billard. The company’s expansion and strong operational performance earned industry recognition in 2024 when Koopman Lumber received Hardware Connection Beacon Award for Best New Store.

Dirk described the transition as a natural step for the third-generation company. 

“It has been an honor to serve as CEO and soon-to-be President, and I’m proud of what we’ve built together,” he said. “Moving forward, Denise brings a fresh perspective and strong financial management experience, and she keeps our values and culture at the forefront. I couldn’t be more confident in her ability to lead Koopman into its next chapter and do right by our employees, customers, and partners.”

As president, Dirk will continue contributing industry expertise and institutional knowledge to support the company’s direction and uphold the values that have shaped the business for more than eight decades.

Incoming CEO Denise Brookhouse said she is ready for the responsibility ahead. “I’m honored to step into the role of CEO, positioning us for continued growth and new opportunities,” she said. “I’m excited to work alongside our talented leadership team to grow thoughtfully and keep our values at the heart of everything we do.”

Dirk emphasized that the company’s success has always been driven by its people. “We believe the strength of Koopman comes from the collective expertise of our entire team,” he said. “Every person here plays a part in shaping the future of our company. We are grateful for our incredible team and what we have accomplished together.”
