Jason Jantzer

Owner / Master Technician

Jason started Jantzer Automotive Services in 2002 after working at Butler Ford for eight years. He rebuilt his first engine in high school and hasn't stopped since. When he's not working on a customer's car, you can find him tinkering on house projects and enjoying time with the family.

Our story

Founded in 2002. Rebuilt in 2021.

    After eight years at Butler Ford, Jason opens his own shop.

  2. The Almeda Fire

    The fire took the shop. Incredible what fire can do.

  3. Help from our community

    Thanks to all the volunteers who showed up to help us clean up.

  4. Back in business

    The shop is rebuilt on the same spot, and we're still serving the Rogue Valley.
