About Us

About Us

Twin Peaks Diesel has been proudly providing service for semi-trucks, agricultural vehicles, mid-size trucks, and passenger vehicles in Frederick, CO and 50-mile radius areas for years. Owners Eric Rexroth and Casey Griebel have been in the industry for 12 years and have owned Twin Peaks Diesel for three years. They are not new to this business!

Our technicians working on your vehicle have graduated from education at DADC Diesel, Front Range Automotive, Cummins Factory Training, ASE Certification programs, and specialty diesel and certification training courses. Our equipment includes the latest technology, and we currently operate two lifts with four light duty and two heavy-duty bays.

Twin Peaks Diesel

We take pride in the fact that a good percentage of our business comes from repeat customers, who trust us with their vehicles. We treat our staff and customers like family, and care about each vehicle that we work with. When you come to Twin Peaks Diesel, you can rest assured that you will get the very best, every time. We do not throw parts at vehicles for a temporary, lazy fix. Quality for us means superior service using quality products. We do not charge for labor or diagnostic work that is unnecessary.

The balance between a great price and usable performance is the Twin Peaks Diesel Difference.
