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

Club Coach & Youth Leader

Hi! My name is Beth Clark and I'm currently applying to grad school in 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!
