Personal Note

I believe I have the respect of all the judges and opponents I continue to interact with on a daily basis as I approach everyone with respect and dignity despite what may be professional differences. I believe one can be a zealous opponent and advocate for a position and then have a beer with your opponent afterwards regardless of who prevailed.

For relaxation I try to golf as much as I can, although nowhere as often as I'd like. I used to shoot in the 80's consistently, but that may be more difficult these days. I've broken 80 twice and I have a double eagle in my career which may surprise you to know is more rare than an ace which I've come close to more than a few times but haven't been able to score. I try to bike most weekends to maintain physical fitness.
