Great mechanic, there is a reason he is back logged with work, if you can wait he is an honest mechanic, with fair pricing, and great customer communication skills. Will bring my diesel back if I ever have issues with it in the future.

These guys are great, knowledgeable and friendly. Prices are always fair and I personally believe that’s getting harder and harder to find. If you need diesel repairs, these are your guys! Ask for either Trey or Ryan and you won’t regret the choice I promise.
