A father's machine shop, a family faith and a shop on County Hwy M

It started with one man, a few tools and a simple goal: do honest, high-quality auto repair without high prices. That goal still shapes every repair at TinJToo Auto Repair in Star Prairie, Wisconsin.

We are a family-run, faith-guided shop, and our story is a big part of why we work the way we do.

Where did TinJToo Auto Repair begin?

TinJToo Auto Repair began with our owner, Jarred Berhow, who grew up in the St. Croix Valley inspired by his father’s machine shop. He graduated from Dunwoody College of Technology and earned ASE Master Certification, then started out on his own with nothing but a jack and a jack stand.

To earn ASE Master Certification, a technician passes all eight core ASE automobile tests, from engine repair, automatic transmissions and manual drivetrains to suspension and steering, brakes, electrical systems, heating and AC, and engine performance, along with hands-on work experience.

TinJToo Auto Repair grew into a Star Prairie shop in 2022

The business started small, with Jarred working as a mobile mechanic with a jack, a jack stand and a goal of doing the job right for a fair price. In 2022, that beginning grew into our shop at 170 County Hwy M in Star Prairie, which gives us the room and tools to diagnose and repair problems properly.

What does the name TinJToo mean?

The name carries our family history. TinJToo honors the original “Tinj” business that belonged to Jarred’s father. Tinj stands for “Trust IN Jesus,” the faith of two generations of the Berhow family. So every time you see our sign, you are looking at a nod to a father’s shop and to the faith that has guided our family ever since.

That faith shows up in simple ways: telling the truth about what your vehicle needs, keeping our word, and treating each customer like a neighbor.

Our history still shapes the way we repair cars today

The goal from the jack-and-jack-stand days has not changed: careful, honest work at a fair price from a mechanic you can trust. When we inspect your vehicle, you get a digital estimate on your phone with photos and videos, sorted into what needs attention now and what can wait.

We take pride in solving the hard ones. Our check engine light diagnostics regularly turn up problems that other shops missed. On the bigger end, we handle engine repair and complete engine swaps and transmission repair. When a larger job keeps your car with us, ask about a loaner vehicle so you can keep your plans.

Honest work also means plain talk. If your brakes have a few months left, we say so. If a warning light comes from something simple, we tell you that too, and we show you the photos so you can see it for yourself. That kind of straight answer is what Jarred set out to offer.

TinJToo Auto Repair serves drivers across the St. Croix Valley

Our Star Prairie neighbors come first, followed closely by drivers from New Richmond and Somerset. We work on Asian and domestic vehicles, from a Honda Accord on its daily commute to a Chevrolet Silverado 1500 that handles the back roads.

Many of our customers drive long commutes on WI-64 toward the Twin Cities, and others rack up miles on gravel county roads. Both are hard on a vehicle, so we keep your driving in mind when we recommend maintenance.
