"Derek has done my big mechanical jobs for me the last few years. Top notch mechanic. VERY knowledgeable. Prices are great. Work is thorough. I HIGHLY recommend him. He'll even takes time to check out issues with vehicles and will tell you how to fix a problem yourself (even if he doesn't do the job)and sometimes has parts on hand to sell you. That's why I take all my more technical and difficult jobs to him just for his experience and his ability to do them (not to mention the specialty tools!"

"While traveling through with my F-550 pulling a stock trailer I lost all power. A local called Derek who came out with a scanner. After realizing it was a fuel issue, he pulled my truck and trailer to his shop. He worked my truck in and even stored my trailer while conducting repairs. A week later I returned to pick up the truck/trailer with a new fuel tank due to old one delaminating and clogging up tank screen. Top notch job! I wish he were closer to my house!"

"Does perfect work, only one that I will let touch my truck, very good prices, only use high quality parts that he knows that will last and runs the same parts on his and family's trucks, if he see something else wrong he will call u and tell u about it and see if u wanna fix it then or wait. Derek takes very good pride in his work, if he pulls something apart he always cleans everything very good before he puts it back on, if u have questions or needs to talk about ur truck he will sit done and go thru everything with u and u will learn alot about ur truck"

"I was in the market for a truck, I called the shop about a truck they had performed work on, and the gentleman had a solid knowledge of the vehicle in question. Saved me a lot of time and effort. This shop knows there stuff when it comes to the 6.0, 6.4 and 7.3L Diesels. I will not hesitate to have work performed here, prices are solid, the work is thorough. 5 Star shop!"

"From Fords to Freightliners, Powerstroke to cats and cummins, they stay busy working on both small and large diesel engines and vehicles. They offer everything from simple service to major mechanical miracles. They will service your vehicles and rotate the tires. They even offer services of taking your vehicle for inspection, wheel alignment, or to get new tires if you like. They gladly provide cursory inspections of any vehicle you may be considering to purchase. They performed an extensive "bullet proof" on my 2006 f350 fx4 after the stock egr had ruptured, and I let the truck set for a year and a half before I found out about them. When they pulled the heads, the pistons were full of antifreeze but they were able to salvage the engine. The truck starts right up and is still working great with even better fuel efficiency than before. Additionally they've done drive train work on my truck and "rust proofing" on the underside. They also do work on gasoline vehicles as well. My son's 1999 chevy tracker broke a timing chain and they sent the head to the machine shop for pressure testing, trueing and necessary repairs. After the head repair and a new timing chain kit, the vehicle ran better than before"
