It is with profound sadness that we share the passing of Bo Mazzetti on May 2, 2025 respected Chairman of the Rincon Band of Luiseño Indians and dedicated ARCHES Board Member. A tireless advocate for tribal sovereignty, environmental stewardship, and economic development, Chairman Mazzetti leaves behind a remarkable legacy of leadership and service to Indigenous communities throughout California. 

We deeply appreciated his leadership in ARCHES, where he championed the Rincon Band’s clean renewable hydrogen project and spearheaded the visionary Hydrogen Trail initiative. This ambitious project aims to connect tribal communities across California, to Nevada, Arizona, and beyond, creating sustainable transportation infrastructure while improving air quality and providing economic opportunities for Indigenous peoples.

Chairman Mazzetti’s absence will be deeply felt throughout the California hydrogen community and by all who knew him. We commit ourselves to honoring his memory by continuing his work and bringing his vision of tribal prosperity and environmental sustainability to fruition. Our hearts are with his family at this difficult time.
