About the owner

I believe in the phrase, "If you don't have the time to do it correctly the first time, when are you going to have time to fix it?"

DempsterGlass Certification

I am Licensed, Insured, and Nationally Certified.


I have been working on cars and motorcycles with my father and uncle since I was young. Over time, I have learned every aspect of automotive repair and modification. I truly love cars.

In 1990 I started in the auto glass trade and have worked for a few national auto glass companies as a store manager and trainer and a couple of small local glass shops.

I have been blessed to work on cars ranging from half million dollar classics and  SEMA show cars, to your family's daily drivers. I have met and worked side by side with some amazing talent over my career and made great friends in the process.

I put the same time and effort into every car regardless of price, and I spend whatever time it takes to return your vehicle to factory specs and crash rating. Every vehicle I work on gets treated as if it were my very own and as if my family's safety depended upon it.

In 2008 I started my own business for the purpose of providing my customers with exceptional service and the highest quality work from start to finish. This could only be accomplished by working for myself, on my time schedule.

I prefer to use OE (original equipment) and premium aftermarket parts, including the best available adhesive systems, (Sika products), so you can safely be back on the road as quickly as SDAT* allows.


Sample Work Portfolio

Dual build-1991 Porsche 911 RWBs. 2011 SEMA cars.

55 & 57 Ford Fairlanes

* SDAT-Safe Drive Away Time, is dependent upon several factors. You will be notified as to how long your vehicle must not be driven. Typically 1-3 hours for most fair weather conditions ( 40* and higher) or heated garages at 40* or higher. For 40* and below weather typically 3-5 hours.
