Did you know that OnSite Truck & Equipment Repair is a woman minority owned business? We value our woman drivers in the trucking industry just as much as we value our male customers. We are passionate about meeting and exceeding the needs of everyone and see you as our guest when you choose to visit OnSite.

We offer a comfortable air-conditioned lounge for you to relax, enjoy refreshments, put your feet up and catch some z’s, watch a movie with some complimentary popcorn (just ask) or tell some jokes to our friendly service writers while you’re waiting for your work to be completed. If we have a driver available, we offer transportation to and from your hotel for convenience during your stay. Be sure to ask for our WIFI password.

We care about our furry friends as well! We keep a water dish out front for our thirsty travelers and don’t forget to ask for a treat for your fur baby if they are feeling like a snack.

Our service writers enjoy meeting new people and seeing familiar faces. We have grown to love a number of our loyal customers as family. Our customers have made a positive impact on our lives and we want nothing more than to continue to exceed their expectations and always provide them with a positive experience every time they visit the OnSite family.

We have some truly amazing regulars and whether you’re visiting to have your vehicle serviced or simply stopping in to say hi or enjoy one of our Friday BBQs with the gang, we value your company and thank you for joining our circle of friends.

We are proud to say that our OnSite employee family is just as diverse as our customer base, ensuring that we have the most talented workforce available.
