Chris Yates

Chris Yates

AMGA Instructor & Coach

I am a simplicated man, a proud Uncle of four who started climbing over 4,500 days ago. I believe climbing discovered me to my first iteration of minimalist living as an actualized truth and has led to a view of climbing as an authentic expression of the dichotomous human condition, one that is unique to each if you allow yourself to “climb on”; yet, subsequently… let go. All in all, family first, climbing always.

Beth Clark

Beth Clark

AMGA Instructor & Coach

Outside of working with Threshold's Climbing Team, Beth is currently studying occupational therapy. "I love watching people grow and develop in any given skill, especially via rehabilitation or in rock climbing. When not in class or at work, I enjoy reading, being outside, running, baking, and of course, climbing. I hope to one day use occupational therapy to help people discover rock climbing as they learn coordination and strength--amongst other life skills--and to recover from hand/arm injuries to get back to the rocks and start sending!"
