A Little More About Me

When I’m not at my desk programming, I am active in the sport of powerlifting. I was a former certified personal trainer with an American Council on Exercise license. In addition, I am big fan of hiking. Some of my favorite trails include the Skyline Loop on Mount Rainer and Burroughs.
