How do you know you can trust Ultimate Truck Service with your truck? We think our experience and the quality of our craftsmanship speak for themselves. Owner Dave Jennerjohn built his first engine for a customer when he was 12. True, he operated out of his driveway, but even as a kid he already had a customer base.

Since those humble beginnings he has gained decades of experience working for various shops and corporations like CAT. But Dave was never quite content with corporate life. So after his kids left the nest to start their own careers he started his own shop, an act greatly spurred on by customers bugging him to come back.

These days, Dave oversees Ultimate Truck Service with the belief that they can take apart and fix anything. So bring your truck in to see what it's like to get the Ultimate treatment.

Thank You Management Success for helping us achieve our goals! You are the greatest!
