In Memoriam
Brian founded Whitson Insulation Company in 1978 with his wife Kimberly. Together, they led the company side by side for over 45 years until Brian’s passing in January 2026. Brian not only served as the company’s president but also handled their sales efforts. He cared deeply for his Grand Rapids community — including his customers, employees, and many industry partners — and worked tirelessly to create a more energy-efficient community that everyone could enjoy. Even with many years of experience, Brian continued to learn something new each time he worked on a project. Outside of his work life, Brian spent his free time camping, traveling with Kimberly, and spending time with friends and family. Brian’s legacy and commitment to “doing things right on each and every project” will continue to be our mission.
