Who is Auto Dynamics?

Auto Dynamics was founded in 2013 despite multiple setbacks and obstacles. It started as just a vision of creating an auto repair shop that specializes in SERVICE. In addition to service, they also fix cars! The goal is to deliver a product that people have not experienced in an independent shop. The Sioux Falls area has plenty of quality technicians and service centers; however Auto Dynamics has quality technicians matched with the right equipment and tools to do the job, plus the will to ensure customers are completely satisfied with their service.

Eric, Marc and Paul all offer unique skills and abilities. With over 45 years of experience they have diagnosed and repaired just about every modern automotive system. They are all ASE Certified and participate in ongoing education. Sometimes it comes down to using resources. Auto Dynamics utilizes factory service information for diagnostics and repair procedures. This takes the guess work out of having your vehicle repaired
