Nisstech provides most repair/maintenance on our Infiniti as well as our American-made mini-van. This has included diagnosis of various issues such as brake noises, fluid leaks, and "check engine" lights coming on. We've also had routine maintenance handled such as tune ups and, oil changes.



What impresses me most about Bill Wallahan's service is his insistence that we do not pay for work that is not necessary. He doesn't repair something unless he is certain it's actually broken. In some cases, this has meant more than one trip to the shop to get something diagnosed, but the cost savings has been tremendous. Other shops have recommended expensive work, but he has discovered that more modest repairs would resolve the issue. Bonus: he has a loaner car available, if you schedule in advance. Bill's friendly service, and most of all his integrity, keeps us driving all the way to Santa Rosa for our auto repair needs.

Service is outstanding! Knowledgeable, experienced & HONEST! I highly recommend Bill & the whole Nisstech shop for any problems with your auto. THE best shop in Santa Rosa!
