Our Staff

Agnes Vianzon

Founder and Executive Director

Hello!  I'm Agnes (she/they), I am a first-generation, queer filipinx, who grew up in the San Fernando and Simi Valleys of Southern California. I currently call Bishop home, ancestral lands of the Northern Paiute and Eastern/Western Mono Monache. My parents would take my brother and I on too-long road trips to National Parks and Monuments which, at the time, I did not appreciate. However, after completing an environmental studies degree from UCSB, I joined the California Conservation Corps AmeriCorps Backcountry Trails Program to live and do trail work in a National Park for 5 months, my perspective completely shifted. Those 5 months in Sequoia and Kings Canyon National Park launched the next chapter of my journey, 10 years of seasonal work - snowboarding and bartending on Mammoth Mountain in the winter and leading young people working trails each summer.  Over those 10 years, I worked my way up in leadership positions on both fronts; including becoming Food and Beverage manager, SEKI Trails Foreman, and eventually promoting to program coordinator for the Backcountry Trails Program. My past experiences became the driving force behind my ambition to start ESCC and expand access and inclusion in the conservation world. With the help of close friends, my community and my supportive partner, I started laying the foundations for ESCC. By 2017, ESCC was a 501c3 nonprofit organization, with an all-women crew being the first boots on the ground. Since then, we have served over 100 alumni and nearly double our programing each year.
