Very very awesome shop! They fixed our wildland fire engine Diesel Ford F550 water pump, and stopped working on what they had been working on before we got here. The owner puts First responders and Veterans First! I highly recommend this shop 1000%.

These guys came in clutch for my wife and two daughters. She was on a road trip to Utah when her fuel pump started going out. They got her in the same day and replaced it for her. The level of service and communication she received is bar none. Thank you guys so much for taking care of my family!

Passing through Ontario on an 800 mile one-day road trip my car had a serious problem and they didn’t hesitate to get me in and fix my car that evening even though they every bay of their garage had a rig they were working on. I had my two young kids with me and they were kind and accommodating to me and my children. They warranted their work and told me exactly what they were doing and gave me an exact estimate prior to the work being done. I was treated with empathy and kindness. I am extremely grateful for them!
