John Haas: Owner & Service Manager


John has been employed by Mike Vinson Auto since October, 1994. He is the “Haas” in Vinson/Haas Automotive as we are now known. John is an Arizona native, graduated from Horizon High School in 1990 and served in the US Navy. John is married to Amy, our office manager and has two sons, Hunter and Brody. With Mike’s retirement in May 2016, John and Amy have completely taken over the daily operations of the business and are proud to have the title “owner”.

As an owner/manager, John’s main tasks include keeping jobs organized, ordering parts and communicating with customers. He is great with customers and always happy to take the time to explain a repair. John is our expert in interior repairs including window motors regulators, door locks, dashes all the little intricate things that you don’t think much about ’til they don’t work!! His other proficiencies include brakes, alignment, tire work and maintenance/service work. As his management duties increase, he spends less time performing mechanical repair. However, you’ll still find him out there working alongside the technicians to make sure work is delivered as promised.

In his “free” time, he enjoys golf, camping & off-roading, hiking, and helping promote high school mountain biking.  John volunteers as part of the Arizona Interscholastic Cycling League each fall, helping to set up infield and organize venues for the five race events held state-wide. Both Hunter and Brody raced as part of the league, but John continues to be committed to providing a great racing event for other students state-wide.
