A Long History of automotive repair in Sonoma County

In 1991 Tristar Automotive was founded by Jim Dadaos, Rick Sanguinetti and Ron Parola. After years of managing and working for a wide array of dealerships they decided it was time to do it on their own.

Between them, they brought over 50 years of experience with a wide range of dealer training from GM and Ford to Honda, Jaguar, Saab, Aston Martin, Fiat, and the list goes on and on. As a result of having many years of experience involved in restoring and collecting cars of their own and for others, they also had developed a vast collective knowledge of the complete restoration process.
