They did a great job getting power back into my cat engine! Very nice people!

I had a semi break down on a Friday about 430pm out in the middle of no where. I called everyone that showed up on Google near and around Havre Montana. Finally I got to Diesel Doctor. They helped arrange a tow as I know no one in that part of the state, diagnosed the truck after hours, had a mechanic in on Saturday and Sunday to get that truck fixed and had my driver rolling by Monday. I know it could have been sooner, if the specialty parts that can only be bought at Peterbilt were available on weekends.Overall impeccable service.

For a small town in montana,this is the best service i ever got so far in my trucking career on the road,not even the bigger shops like peterbilt or kw stand a chance with the professionalism and knowledge these people have,very clean shop,friendly people and very helpful.I will highly recommend this shop.i had an electrical issue,they got on it right away and i was back on the road in no time.Dusty worked on my truck,talk about a down to earth person thats him,and his knowledge and profesionalism was outstanding.This is my go to place to get anything done on my truck.

Great People to work with - will do what they can to get you up and running in a timely manner. John - EJ Vandenberg Trucking LTD

I called them a week ago for an appointment for this week. They said they would call back in a couple of days to confirm an appointment. They never called me back, so I called them today to confirm an appointment and they said they dont have an opening until Monday. I cant make that appointment since we are going back on the road Monday. Horrible customer service to say the least.....

Outstanding service Im a long-haul trucker who broke down not far from here they have the part and work me in and I was back on the road in about an hour highly recommend them

They are very busy and fit me in as Im from out of town.Fixed my problem.The place is very clean and they are very nice people!

Great people & shop. Shaylan and Scott are a joy to work with. They are friendly & really care.
