I love to motivate with kindness, passion—and the person sitting next to you! The most important (and initial) instruction I give to every class is to smile, and say "hello" to your cycle friend and neighbor. A welcoming smile and some good tunes will help you pedal a little harder, sweat a little more and feel better and stronger when you walk out the door. I promise!

My motto is "two wheels over four wheels—anywhere and everywhere". I have traveled thousands of miles and through multiple countries in the saddle, self-supported and with beautiful views. It’s a beautiful way to see the world—so ask me any time about cycling and long-range touring.
