We build the vision.
Bill & Cindy Gallaher began building homes under the Gallaher Construction name in 1979, starting one home at a time. For many years, Bill personally designed the floor plans and oversaw the construction of each home, gaining extensive, hands-on experience that shaped his deep understanding of the building process. Over time, their work expanded to include a wide range of projects beyond single-family homes.
OSL Construction emerged as the evolution of Gallaher Construction and now serves as the construction division of Gallaher Companies. As the company’s longest-standing business unit, OSL is led by Construction Director Wade Thompson and a skilled team of superintendents. Together, they manage and build diverse projects—including senior living communities, multifamily developments, shopping centers, and single-family homes—across the western United States.
OSL LEADERSHIP
Our Superintendents and support team is led by our Director of Construction, Wade Thompson out of our Sonoma County headquarters. With a focus and commitment to high quality construction, Wade and his team churn out projects throughout the Western States exclusively for Gallaher Companies.
