Highly Recommend!! Mitch is definitely an expert when it comes to diesel engines. He not only did a great job on fixing our issues, he gave us great advice on maintaining our truck. He saved us a lot of money which is always a plus. We requested an oil change and cleaning of our exhaust system. Since we were waiting on a part that we requested to have installed, he held off on the cleaning of the exhaust knowing he would need to pull those parts again for the new after market fuel pump. He found a broken sway bar link and was able to fix that as well. Overall, we are so pleased with his work, his knowledge, his patience to explain everything to us, and his valuable advice to keep our truck running great for 200,000+ more miles. We will be using him for future oil changes and anything else that may arise. Great guy all around.
Instant assistance with knowledge and above and beyond service. Fixed my cooling issue and radiator. Great followup and fair prices. Specialize in Diesel engines. They are the best!
MDS recently serviced my F250, they were professional and knowledgeable. I will definitely be back for future services and I recommend them to anyone looking for a reliable diesel mechanic.

I drove from Salt lake city to Havasu to have Mitch do some time consuming upgrades on my duramax. Extremely knowledgeable, everything was done in half the time the service book required. His prices are more than fair, doesnt skip any steps and only uses top of the line parts. Would never hesitate to have mitch to any job, big or small
