Mattern's Diesel Services has been a cornerstone of the Aberdeen trucking community for over 15 years. We started as a one-bay shop with a conviction that diesel operators deserve better — better communication, better diagnostics, and a mechanic who actually cares whether you make your delivery on time.
Today, we're still that shop. Family-owned, locally rooted, and deeply familiar with the demands of life on the road. Whether you drive a heavy-haul semi or a work truck, we give you the same attention we'd want for our own rigs.
We know the frustration of a shop that overcharges and under-delivers. Here's what you can actually count on.
We're your neighbors. Aberdeen is home, and we take pride in serving the trucking community that supports ours.
We explain what's wrong, what it'll cost, and what happens if you wait. You approve the work before we touch your truck.
Time is money in this business. We prioritize getting you back behind the wheel — safely and efficiently.
Schedule your service today — or give us a call if you need help now. We're right here in Aberdeen.
