Conrad Johnson aftermarket upgrade

Hi folks: I remember there was a gentleman who was a former CJ employee that has started his own company and takes in Conrad products and performs very effective upgrades. I know he lives in Virginia and I believe in the Fairfax area. Does anyone have a line on who he is and what his Email address might be?
Damn, I would REEEEALY like to know as well.
I believe you are speaking of Bill Thalman, former c-j design engineer who now operates his own business in Springfield, Va. His phone no. is 703-764-7005. I have known him for about 20 years, have used his services many times, and can attest to his fine workmanship, and friendly service
