Why the Rebelle? Why now?

I'm one of those people who believes I can do anything if I set my mind to it, and the Rebelle Rally is the ultimate challenge to that. I want to push myself and my vehicle to prove that I am capable of accomplishing more that I may have thought possible.

Who, or what, inspires you most?

I'm inspired every day by my wonderful, kind, loving parents. They've supported me in all of my crazy ideas and have always encouraged me to dream big and be fearless. They've built a life full of adventure and inspire me to do the same.

Greatest adventure to date?

Studying abroad in Iceland for a summer. I stayed with a host family in Isafjordur and planted trees on their afforestation farm, traveled through the center of the highlands and stayed in off-grid cabins along the way, climbed mountains and waterfalls, and swam in the ice-cold fjords. Truly an incredible experience.

I wish I had time for these…

Greatest adventure to date?

Tough choice – 3-month study abroad in the South Pacific in 2001, or the adventure of a lifetime that began when I started dating my now-husband a few months later. I’ll go with the latter! Alex is my rock, and we've enjoyed numerous adventures together!
