the Diesel Experts Near You

The founder, Ethan Olsen grew up on a farm, where his interest in motors started at an early age. He worked in small repair shops and became an ASE Certified technician. Ethan gained hands-on experience in a variety of diesel applications, including construction equipment, dealerships, and marine engines. 

While working at other shops for years,  he realized  there was a gap in the area for a top-notch diesel and off-road shop, that offered fair and reasonable pricing.  He opened NW Diesel which has become the premier diesel shop in Western Washington and became known for their diesel conversion services. 

CDA Diesel was born out the Olsen family's new-found love for northern Idaho and their desire to bring their experience and expertise to the area.
