More than five decades on N Dutton Avenue

Hahn Automotive has been the trusted name in auto repair in Santa Rosa since 1969. Owner Billy Coughlan started at the shop in 1979, worked his way up through the ranks, and bought the business in 1989 — bringing more than four decades of personal commitment to every car that rolls through the door.

We're an independent, family-owned shop, not a chain. Our ASE-certified technicians service every make and model — domestic, import, hybrid, diesel, even Tesla — with the experience and equipment to handle jobs other shops turn away. Every repair is done with integrity, explained clearly, priced honestly, and (if you're lucky) supervised by the shop dogs.
