Naomi & Jaime Hjelm

over the past decade, many of our friends (mostly female) have come to us for a second OPINION with their AUTOMOTIVE repairs. we find it truly amazing what some shops quote people to get their cars fixed, and not in a good way.

our decision to open our vehicle repair shop to the general public in 2018 was to offer a “lower than normal labor rate” with efficient service.  We want to make a positive difference in the auto repair industry.

our goal from day one is to have affordable and honest prices and are completely transparent -we are below the average prices for most services. We won’t upsell on services you don’t need. We feel it is very important that everyone feels comfortable getting their vehicle repaired. we include pictures and drawings if helpful or necessary- if you are on site we will show you whats going on. We also offer free classes to our community on automotive basics.

  • Jaime started building transmissions on our taxi fleet when she was 17 years old; then moving into general mechanics. Jaime has run the taxi fleet repair shop for many years until we shut down the taxis in 2024. Jaime teaches automotive basics classes in our shop and also has been invited to speak at local libraries and private ORGANIZATIONS to help individuals learn about their vehicles. Jaime is talking to the customers and diagnosing vehicles on a daily basis from open to close, ORDERING parts,and mentoring the next generation of technichians. She keeps all the techs on track with the tasks of the day, visually sees every car. if there is time she will work on the vehicles as needed.

  • Naomi has always been on the "it technical" part of the business along with all the boring paperwork. she brings the technology to the businesses and cuts the paychecks and pays the taxes. Naomi helps with phone calls and also greets customers.

    Together with our tech’s we make a great team in order to give our customers the best experience.
