Mark Grundon

I am an AMGA-certified rock climbing guide and have been guiding all over the US, from Colorado to Alaska, for 10 years. I currently split my time between Potrero Chico in Mexico and Yosemite National Park.

I am a strong believer in "living the dream" and recently retired from ski patrol to devote all my time to my true passion: climbing. I enjoy climbing both with Yosemite's biggest stars and first time climbers.

Among the achievements I am most proud of are 1-day ascents of El Capitan and Half-Dome in Yosemite. Contact me for an amazing climbing experience in Mexico or the US!
