Ruben Rodriguez
Community Organizer & Air Monitoring Specialist

My name is Ruben Rodriguez, a native of the western hemisphere. A father, son, brother, uncle and protector of all our relations. I currently reside on occupied Yokut/Tachi land in what we now call the great central valley. Sacred land that was once home to the great Tulare Lake. Now dried up and transformed into a multi billion dollar agricultural and dairy industry. As a resident of one of the most polluted air basins in the nation it was hard for me to make the connection between what was happening around us. Now as a community organizer/air monitoring specialist, I’m able to make that connection and understand why some have come to call this great valley a sacrificial zone.  The Central California Environmental Justice Network has provided me with an opportunity that allows me to advocate for resources and services that will help underserved and marginalized populations in the central valley. Frontline communities like San Joaquin, Mendota, Huron, Raisin City, Kettleman City, Cantua Creek and Avenal that continue to deal with underrepresentation and lack of resources in a state with the 5th largest economy in the world. 

Rocio Madrigal
Community Outreach Worker

Rocio was born in the Central Valley to immigrant parents. Both were from frontera towns and came to the U.S.A. She began her advocacy work in high school when she became involved in Proyecto Popular in 1990. Her parents knew the importance of keeping Spanish in her life, so she completed her medical interpreter internship at the Children’s Hospital in Madera. She attended the University of California, Santa Barbara, completing her Associate’s Degree in paralegal studies. She most enjoyed the enforcement section of the labor and employment law. Rocio has also worked on the Census and conducted COVID testing alongside UC Davis researchers. Rocio often travels to rural communities in Fresno County and finds ways to link CCEJN clients with other helpful services.

In May of 2020, Yelisa graduated from the University of California Berkeley with a B.A in History and a minor in Chican@/Latin@ Studies. During her childhood and within her time in higher education, Yelisa became heavily involved with activists that advocate for farmworkers, immigrants, and other marginalized groups. Moreover, in her time working with community-based organizations, Yelisa has managed to educate communities on their rights, organize marches in the streets for peace, as well as provide resources to families in need. A poet in her free time, Yelisa writes about her experiences growing up in the Valley. Her dream is to improve the lives and living conditions of immigrant and farmworker communities in the Central Valley by educating, preserving roots, and reconnecting them to their cultural lands and traditions.
