About Me

My wife Rachel and I both grew up in California. We both lived in South America for a stretch (that's where we met!) and we both love to travel!

I build websites, and I wish I thought of starting couchsurfing because it's the best. Check out my (largely abandoned) website: http://trekhard.com

Why I’m on Couchsurfing


I have hosted some people with a roommate before I got my own CS account, and I am excited to host more people in the future. I also made many friends around Europe in summer 2009, and in Buenos Aires near the end of 2010. I hosted a few times in Tahoe in 2011, and surfed (unofficially) with Peace Volunteers all over South & Central America in 2012.

Since then have only surfed and hosted occasionally.


I lived in an "International House" in San Diego which had about 100 foreigners as residents. During breaks, when everyone wanted to travel, I hosted as many as 12 of them at a time in my family home near San Francisco.

That's what got me started...

One Amazing Thing I’ve Done

I traveled from Patagonia back home to San Francisco, California without setting foot on an airplane.

Teach, Learn, Share

I have tons of random skills to share. Maybe I can help exchange languages, too.

What I Can Share with Hosts

Time and chats and laughs and hopefully friendship.
