Board and Staff

Agnes Vianzon, Executive Director

Agnes Vianzon

Agnes (she/they) is a first-generation, queer filipinx, who grew up in the San Fernando and Simi Valleys of Southern California but currently calls Mammoth Lakes home, ancestral lands of the Northern Paiute and Eastern/Western Mono Monache.  After completing an environmental studies degree from UCSB, she joined the California Conservation Corps AmeriCorps Backcountry Trails Program to live and do trail work in a National Park for 5 months, which completely changed their perspectives. Those 5 months in Sequoia and Kings Canyon National Park launched 10 years of seasonal work – snowboarding and bartending on Mammoth Mountain in the winter and leading young people working trails each summer.  On both fronts, Agnes worked the way to leadership positions until eventual promotion to program coordinator for the Backcountry Trails Program.  Leaving that program in 2015, less than 2 years later, ESCC became a 501c3 nonprofit and the first boots on the ground was and all-women crew. Following her passion, Agnes is the founder of ESCC and believes in the power of the outdoors to provide a transformative experience.

Valerie McCampbell, Program Coordinator

Valerie, second from the left, has been involved with ESCC since our first season in 2017! She started trails doing the Backcountry trails program in Kings Canyon National Park in 2015. Since then, she’s had the privilege of exploring and working in a variety of National and State Parks in California and Minnesota. Conservation is her passion and the ability to teach and share that passion with others makes them proud to work for ESCC. She is proud to be a Black/Mexican woman and it makes her heart full knowing that she is adding to the representation and inclusion for these beautiful lands to ensure that they are an accessible and safe space for everyone!

Steven Addison, Board Member

Steven joined the California Conservation Corps (CCC) in 1994 and had the privileged to serve on the first Americorps crew at the Del Norte Center.  During that season he gained his love for working and living out doors.  In 1998 he was selected for the Backcountry Trails Programs and served on the Yosemite II crew.  He would continue working trails in Yosemite and Big Bend National Parks.  After working on trail crews for a few season Steven was hired by the East Bay Conservation Corps as a Field Supervisor.  Working with corpmembers in the East Bay was a way to give back to the community that raised him.  Steven was able to bring many of the lessons he had learned in the CCC and the Backcountry to the East Bay.

Most recently, Steven had been working as a project manager with the Northern California Resource Center (NCRC).  NCRC contracts with the US Forest Service to conduct riparian and fisheries studies throughout the Klamath National Forest.  Now, Steven has decided to come full circle and join the Civicorps team as our Job Training Coordinator.  His knowledge of conservation projects and experience working with youth will serve to promote our mission well. We are happy to have Steven serving on the ESCC Board of Directors. Learn more about Steven here:
