"I highly recommend this shop. I had luke a technician there do some work on my truck after a ford dealership took 6 days and failed to acknowledge my warranty on 3 leaking oil spots on my truck.Once the dealership screwed me over I took my truck here. Luke was very impressive, fast and communicative. He provided me photos. He kept me updated on everything he did. I still have a warranty through ford but apparently it’s useless. I don’t think I’ll ever go back to them considering how they treated me. Luke is a solid technician who is very skilled. I can’t recommend him enough. Thank you."

"Our truck broke down just as we were getting into Denver. It was a major repair and they accomplished it quickly and we were back in our truck. Everyone there was very professional and nice to work with. The unhappy news of a major repair was actually a good experience. Definitely recommend Iron Buffalo."

Kelly

"I’m glad I went to this shop. I was so worried it would be another back door mechanic wanting to swindle me. It was anything but. Shannon was super kind and went way out of his way getting me in right away. And Steve was a professional from start to finish in assisting with the work being done. I’m really appreciative and would 100% use this shop again."

Kristin

"Steven Riddle is the best service writer if ever dealt with. He is very knowledgeable, I called with starting issues. With in 1hour try had my truck towed in. That day they had it diagnosed then next day they found the parts. Great job, I will be using in the future. Thanks a lot."

Mike

"Kanisha was great, I had been trying to get my small hydraulic cylinder repaired for quite some time and she was the first person that said "YES" she was honest about needing to look first. She was willing to listen and explained the process. When I came in she was polite and professional. She communicated like she said she would and got it taken car of! I'll recommend Kanisha and Iron Buffalo!"

Lance

"I'm very happy with the service I received from Iron Buffalo Holdings I highly recommend this shop. I got an Inspection & a DYNO done on my Semi Truck. Canesha was prompt and courteous."

Miko

"Had a break down with the ol’ Pete they picked up and were available l. They aren’t the cheapest but heck you get what you pay for. If you want your rig or RV fixed so you can head one down the road these guys are nice and they can almost always get done in a day if you need it."
