My name is Al  When I started repairing vehicles I told myself that people need help and so much more these days because there are repairs being made to vehicle's when the parts that are being replaced are perfectly fine. I look forward to gaining your trust as I have with so many people I know from church that trust and bring their vehicle's only to me.

About Us

Here at BIG A Auto Repair we work hard to make sure you save as much money as possible, this is our number one goal and always will be.

I have been into automotive repair for over 40 years. I started out as a helper at Bob Conklin service station as a mechanic, changing starters, battery's, tire's. You know small stuff. Then I moved on to a used car lot where I learned to work on anything that moved on the road.


I decided one day to go to automotive school and learn more about everything to do with vehicle repairs. Shortly after that I landed a job in a car dealership that immediately started sending me to school and I moved up from a mechanic to a technician.


I worked hard learning every field of automotive repair and some years later gained my ASE Certification and on to my Masters Degree. After 40 years of learning and helping others on the way, now I'm helping people with vehicle problems save money in their time of need. Hope you enjoyed the story of my journey and I hope to help you in the future.
