Brian can repair anything diesel, but his area of expertise was rebuilding diesel engines and transmissions. After earning a degree in automotive repair from Northeast Wisconsin Technical College, Brian worked as a diesel technician in central Wisconsin for 24 years before he and Wendi purchased Diesel Specialists.

With the help of their dedicated employees, they have built a reputation as one of the premier diesel repair centers in Wisconsin.

Testimonials
Was having some trouble w/ my 2500 diesel, these guys were able to diagnose it quickly and were straight up about the repairs required. They didn’t try to sell me on anything special, they took care of the repairs that were needed in a most cost effective manner and offered suggestions on repairs for the future.
Their mechanics are diligent and professional and imo some of the best in the industry, best of all they’ll explain things the way they are. If you can handle the most technical of answers they have it, if you need a more distilled version of that answer they can do that too. The service managers are a pleasure to talk with, very professional, patient, and have a genuine understanding of how to communicate between customer and mechanic.
Diesel Specialists are exactly that and are an outstanding shop. They made my truck work, so i could work.
