Hi, I'm Stephen Zenzen, owner of Cornerstone Auto Pros. I've been doing real body work since I was ten years old — not sweeping floors, but hands-on repairs. When you leave your vehicle with me, you're trusting someone who has spent his whole life mastering this craft, and who's committed to doing every part of it right.
I grew up in my father's body shop. He opened his own in 1995 and built it into one of the largest independent, non-insurance-direct shops in his city — still running today. By ten I wasn't just hanging around it; I was doing real body work, trained mostly by his technicians, and I never left the trade.
For the last 15+ years my focus has been paintless dent repair, with hail as my specialty. I spent part of that time in the traveling-hail world — chasing storms across the country — and while that's not the life I wanted long-term, it gave me something rare: I've seen nearly every kind of hail job there is, and I know the repairs, the vehicles, and the insurance side of it inside and out.
In 2022 I established Cornerstone Auto Pros and put down roots. I traded the road for a real shop, a real community, and a full, meaningful life with my wife and family. This isn't a storm-chasing operation passing through — it's a business built to stay.
My faith in Jesus shapes how I do business: honest work, straight answers, and a repair I can stand behind every time.

Hail and paintless dent repair are my focus, but they're not the limit of what I do. Over the years I've done the full range of high-skill collision and refinish work — which means I always know the right repair for your vehicle, and I'll tell you straight when a different approach is the better call.
My goal on every job is the same: a repair that's excellent and completely clean — legally and every other way. I handle your claim by the book and keep everything above board, so the way your repair was done never comes back on you. Your car is protected, and so are you. If you've ever wondered about shops that offer to "cover your deductible," here's why I don't — and why that protects you.
Every repair, I document. You can watch real hail damage come apart and go back together on our YouTube channel — no mystery, no hard sell, just the work.
