William discovered Yoga in 1995 on the simple path to becoming a better rock climber. He learned Yoga is a lot more than building core strength & flexibility.
“Practicing Yoga is a great compliment to any hobby because of the powerful psychological benefits & body connection to breath. This metaphor is infinite as the power of breath is used every day, especially when we confront fear & anxiety. The simple yet profound path to learning how to master our breath makes our life more manageable & teaches us how to let go of stress & tension in a healthy sustainable manner.”
In addition to practicing victorious breath, William loves how Yoga reminds us to slow down & stay connected to living in the present & being aware. Learning to do this this brings us peace & joy when we most need it.
Invigorated by Yoga, William completed multiple Yoga Teacher Trainings at Akasha Yoga in Davis & CorePower in Berkeley. When he isn’t teaching Yoga, he can often be found rock climbing in Yosemite.
