About the Family Business:
About the family business….
A1 Auto & Transmission repair shop is located about a quarter mile from the Shepherd post office an a few feet from their home. Before opening his own shop in 2006, Aigner was employed at Rimrock Auto and Frontier Chevrolet in Billings as well as Rapid Chevrolet in Rapid City, SD but he says he’s been working on cars since he was a kid.
“My grandpa was a mechanic,” Aigner says, adding that he has been a mechanic since he graduated in 1981 from Newell High School in Newell, SD. He attended the University of South Dakota at Springfield in his home state, and eventually moved to Montana for a change. The Aigners made the move in October of 1993, and have been in the Shepherd area since 1994.
“I started in a little two-bay Chevy dealership in Faith, South Dakota, now I’m in a shop of my own with repeat customers and new ones added weekly sometimes daily” Aigner says.
As a GM mechanic, Aigner was ASE Master Certified for the last 20 + years. Now called the Mark of Excellence, Aigner was the highest-ranked mechanic in the five-state region last year. It is a nationwide test that shows the mechanic’s knowledge on all GM products. Aigner was also Platinum Master Certified, which is an honor that brings a gold ring and one diamond for each additional year of the certification. He has earned five or six diamonds. Aigner is proud of the accomplishments, but does not wear the ring for safety reasons. He is GM certified, but qualified to work on any make of vehicle.
“I strive to keep up with the training and certifications,” Aigner said, noting that the industry moves so fast that it is almost necessary.
Todd’s wife Jenny does the bookkeeping and parts running for the small business. They have five children, the oldest, Tyrell, is following his dad’s footsteps and currently working for Denny Menholt Frontier Chevrolet as a line tech, Tambria, Leah, Thomas and Kennedy are all students in Shepherd School District.
The shop offers all that a dealership does in the way of repairs, including specialized information. “It’s worth it to seek out professionalism,” Aigner said, adding that there are many qualified professionals out there. “You can get good quality at a reasonable rate, and you don’t have to go to a dealership.” Todd specializes in complete GM and diesel repair.
