I call Chicago home. Great food, arts and architecture, and a beautiful lakefront bike path — what's not to love?

Skiing and Snowboarding

It's been a few years since I've had a chance to get out on the slopes. I love skiing in the Vail area of Colorado, but when I can't be there, you'll find me at Cascade Mountain near the Wisconsin Dells.


I've been playing for a few years now, and I'm looking for others to play against. If you're interested, please let me know!


As an amateur photographer, I enjoy experimenting with new techniques to create unique effects. I shoot with a Canon 5D MkI and (usually) a 50mm f/1.8.

Scuba Diving

I have logged a few days worth of dive time, predominantly in southern Florida and the Keys, and also in Negril, Jamaica.
