Tanner Ditmore. Owner & Lead Mechanic
Tanner has been taking things apart to see how they work for as long as he can remember. He spent years in other shops taking on the diagnostic problems nobody else wanted.
He opened True North to fill a real gap in Tumalo. A local shop you can actually trust. Honest answers, quality work, clear communication.
He's raising his family here in Central Oregon. The neighbors he keeps safe on the road are often literally his neighbors.
“I'd rather find the actual problem than sell you a part you don't need.”
“Three services so far. Two oil changes and suspension work on my truck. Reasonable prices, top notch work, and easy to communicate with. Low stress from start to finish.”
“Skip the clueless big corporate guys and go to the skilled techs at True North. Worth it for the peace of mind alone.”
“There isn't an auto shop in Central Oregon I trust more.”
“Fair, fast, and honest. Exactly what you want from a mechanic.”
“Tanner walked me through every line on the estimate. No pressure, no upsell.”
