Whether it’s backpacking, climbing, biking or botanizing, I cherish fully immersing in captivating landscapes. I have a passion for public outreach and educating on behalf of the wild. I’ve visited Costa Rica, Spain, Nepal, Ecuador and the Galapagos, which have shown me the importance of maintaining an open mind to maximize your experience.

Region: North America, Yosemite, The Sierras

As a Michigan native surrounded by the Great Lakes, water and outdoors always played a central role in my life. My path to the Sierra Nevada has been spontaneous, including adventures in New Zealand, working in outdoor retail, and a bike tour across the South. I’ve found that the best way to protect wild places is to authentically share the outdoors in all its natural beauty.

A Bay Area native, I studied linguistics at UCSD and worked as a paralegal in San Diego. Instead of law school, I took a sabbatical to live on a fishing boat in Alaska, which ultimately led me to my dream job as a guide. I love meeting people of all ages and backgrounds and that my office is the great outdoors.

Growing up in the Chamonix Valley in France, the mountains are an integral part of my life. I have led nearly 50 trips to the Alps, not counting how many times I’ve done this trip for my own fun! In addition to guiding, I am a skier and climber.

An avid sports enthusiast and inexhaustible hiker, I’ve hiked the Tour du Mont Blanc close to 100 times. I have been guiding for MT Sobek since 1995, and when I’m not guiding, I teach First Aid and Mountain Rescue to mountain and hiking guides. During the winter, I’m a ski patrol monitor in the mountains above Chamonix.
