The Guys

Jason Jantzer


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 is not working on a customer’s car you can often find him restoring his ’66 split window bus or his old Caterpillar tractor.

ASE Certified



Andy has a passion for all things cars, particularly pre ’70; some might even call him a hot-rod fanatic. He too has been working on cars all his life and began working for Jantzer Automotive mid-2012. In his spare time Andy likes to work on old hot-rods like his ’38 Chevy Coupe.
