Bill and Cindy Gallaher started building homes under the Gallaher Construction name in 1979. They started one house at a time, and for years Bill designed the floor plans and built or managed the construction of each home himself. Those years of on the job experience gave him an intimate knowledge and understanding of the construction process. Over the years they developed and built a large array of projects in addition to single family homes.
OSL Construction was born of and is the continuation of Gallaher Construction. It functions as the construction arm of Gallaher Companies and is the longest operating sector of the business. A team of superintendents, now led and managed by the company’s Construction Director, Dave Hunter, enables the successful building of projects such as Senior Living Communities, Multi-Family Projects, shopping centers and single-family homes throughout the western states.
Our Superintendents and support team is led by Construction Director, David Hunter out of our Sonoma County headquarters. With a focus and commitment to high quality construction, Dave and his team churn out projects throughout the Western States exclusively for Gallaher Companies and Oakmont Management Group.
