Meet the Owners

Paul and Jennifer Teigrob are Whatcom County natives and share a common interest in all things automotive.  From an off-roading first date, to wrenching together on personal projects for the last 14 years, birthday trips to SEMA, doubling the horsepower in the daily driver grocery getter, these two are a match made in automotive heaven.

After working on personal projects for years that drew the attention of people locally and online worldwide, the Teigrobs decided it was time to take their passion full time and haven’t looked back.

Paul has both dealership and ASE master certifications, an overall focus on drivability and safety, and ability to take your ride to the next level.  

Among our past and current builds are several award-winning vehicles, restored family heirlooms, and vehicles with unique drivetrain set ups requiring custom fabrication.


Paul and Jennifer are proud to be the go-to shop and that other shops refer those tough or involved jobs to, we are ready and able!
