What Makes Us Different

Since 1920, Schimpf’s Garage has been family-owned across four generations. When John took over and rebranded as Schimpfs Heavy Duty, his goal was simple: protect the legacy and build something stronger for the future.

Testimonials

Hear From Our Valued Clients

See All
I have a 2008 Chevy Silverado 3500HD 4wd that was in need of a front end alignment. Their front end alignment service came highly recomened from a Chevrolet dealership. I was thrilled with the outcome. They are pleasant, professional and helpful. I see why the dealer endorsed them as a great place to go for service. Thank you Jennifer for your help.
Meliane C.
As always, very satisfied. Jennifer always very friendly and keeps me informed promptly of outcome of service and future service details and costs. Mechanic very nice and took time to get in car to see if noise i was hearing was resolved.Always such a relief to know a great "honest" car service garage is nearby!
Steve B.
I brought my 1975  Corvette in for an alignment, and these guys did an excellent job. They treated the car with care and respectIt’s hard to find a shop that still knows how to handle older classics the right way, but this crew clearly takes pride in their work. Professional, knowledgeable, and thorough — I wouldn’t hesitate to bring any of my vehicles back here. Highly recommended.

We've had multiple services done on both our cars, and it is always a good experience. Fair and transparent pricing. Jennifer is amazing; communicates well and does not pressure you into add-ons.  Schimpfs is a trustworthy, local small business I am glad to support.
Laurie G.
I had an issue with my car where it would start then I come in and then it wouldn’t start. My battery was fine. My alternator was fine. My starter was fine. They stated that it was something that was joining power from my battery. I brought it in, took them a little bit, but they found what the problem was and I think that it was reasonably priced for what they had to go through. Thank you so much.
Tina C.
They have a long legacy of being the best in the suspension and alignment game my grandfather used Schimpfs for his Trucking company repairs. They got me in quickly figured out my issue and did great job explaining it and gave me no pressure options on repair. Very happy with my experience. All these years later it’s great to see local companies maintaining the same quality and integrity. Would definitely recommend them for all your automotive needs.
Jay I.
They did a total break replacement on my vehicle.  Communicated the entire time.  Provided line by line estimates via an extremely easily accessible online system and did no work without my go ahead.  The mechanics also took the time to send video and detailed photos of any and all problems found within the vehicle. They were even nice enough to watch my car for the two days it took me to get back up there! Great experience all around and will most definitely return for any and all future vehicle endeavors.  Plus… what a RAD sign!  I want a t-shirt.
