Since 1985, Dennis Goodhue has set the gold standard for auto repair in Montrose. Thanks! Dennis started life farming and repairing farm equipment.

Diamond G Repair was started in 1985 by Dennis Goodhue in a two-car garage. After two building changes, lots of training, and years of experience, we have grown to a new and modern six-bay facility with six techs. His upbringing on a farm taught him how to fix things himself and to keep repairs affordable, skills which he brought to Diamond G Repair later on. Soon enough, there was no time for farming because the demand for other local repairs took all of his time. Adding the shop’s first employee was a big step and we have not looked back since. When we moved into our current building in 2009 we added services like alignments and exhaust repairs. We offer custom modifications and accessories, specialty welding (all metals), and thread repair. Our staff is trained to be up to date on technology and we strive to have the latest equipment to accomplish top-quality repairs. Our goal is to provide timely, competent service at a fair price. We value honesty in all aspects of our customer relations. OUR VEHICLE REPAIR SERVICES
