As a child in a family of migrant farm workers who turned into community organizers, Cesar was exposed to community organizing and advocacy at an early age. Since starting with CCEJN, Cesar works in rural communities in Kern County helping fenceline communities affected by oil and gas and pesticides understand how to protect themselves from these sources of pollution and how to advocate for systemic changes that prioritize their health. Cesar has participated in multiple projects (i.e. Arvin Air Quality; I.M.P.R.O.V.E) where he has trained residents on how fracking and other activities related to the oil and gas industry are negatively impacting their neighborhoods. He has also trained community members on the collection of data using PM monitors and bucket samples.
