Trained Professionals and Mechanics That You Can Trust

Jeff LaGrave

Owner

Jeff began his career in 1980, when he joined the US Army and spent time in Germany as a tank mechanic. Over the years, he became an expert in the diesel repair industry, working on heavy equipment including tanks, dozers and tug boats. In 1992, he moved to Sonoma County. In 2008, during a major downturn in the economy, he was offered an opportunity to purchase the garage. Trusting his expertise and with the support of his family, friends and the local community, he made the leap! Jeff’s Twin Oaks Garage has become the successful, go-to shop for diesel and truck repair across Sonoma County.
