About Us

Built on honest work and a handshake

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.
