Great truck repair shop...you cant beat the personal there! Nicest people in the industry...

Great shop, owner Shad is extremely knowledgeable and a master in his craft.

I went there with front axle vibrating. Came out with the issue fixed but steering wheel have big freeplay. And i have to go to another shop to fix it. Also i told them to fic air leak and they didnt but they charged. So rethink before you go there. Prices are also little high.

I am highly recommend this shop. Very professional accurate and honest place to bring your truck and specialty volvo place.They help me be on the road in 2 days with injector issues solved my long problem issue of no power !!!!!All can say that fleet will visit them more.Thank you

Prices are inadequate.. Work, in many instances, might be required to overdone.

Friendly, competitive, and professional. What else can I say. Ill take all my trucks to them from now on.

Nice service, friendly stuff,good price!Thank you,Joan!

Highly recommend, thank u for your professional service

Good place family owned shop i deal with them daily basis every time they do good job on my truck shad is the guyIf you are in Denver area I highly recommend to give them a shot.

I love this place and I think they do a great job. My only concern is how long it takes I wish I could get my truck fixed sooner. But the quality is superb

Absolutely the BEST mechanic in Colorado!

I had an alternator go bad I asked shad the owner of cornerstone if he could get me in, most shops in Denver are a 2-3 day wait.Bring it in he said.Had dropped the trailer at another shop for an air can bracket to be repaired a $50 part easy job I thought. The other shop was swamped so they sold me the part and I asked shad if he’d do the job.Yes was the answer.Than I also had a bad wheel seal and oil soaked brake.Job ended up going until 10pm at nightThey close at 5pm.Shad let the workers go home and fixed my truck himself.I needed this truck fixed I had a load to pick up the next morning.The team and shad went above and beyond to get me 100% legal for the DOT blitz.If I have trouble with my truck in Denver,Cornerstone will be the 1st shop I call.Thanks again!Great jobBob BakerRWAY Transportation

Love these guys,they take time to listen to your issues,and will get you going pretty quick.

Great service! Alternator change in almost 1 hour, not overpriced, good job!

Great guys. You can tell they know what theyre doing. Highly recommended.

I called the shop and theyve told me that they have availability to check my truck but it took them three days to start diagnostic so I called them after waiting for that long but theyve provided me with an outrageous price of the part from GMC so I called GMC dealer and I got the same part with two third the price theyve told me for the part then I took them another week to finish replacing it ( high pressure fuel pump) with outrageous labor price as well so They are so expensive and took them two weeks to replace a fuel pump. in addition, they are really bad in customer service since they asked me to not call again till they call me but theyve never called and I mean never

Great service,i had my truck broken down and licking, they took me in the same day ordered parts overnight and had me out the next day 💯
