The San Manuel Band of Mission Indians, officially the Yuhaaviatam of San Manuel Nation, is a tribal government serving a reservation spanning over 1,100 acres in California's Inland Empire. Established in 1891, the organisation functions as one of the region's largest employers, operating comprehensive tribal governance including legislative, executive, and judicial functions through its Tribal Court system.
The band's work encompasses cultural preservation - actively maintaining Serrano language, traditions, and heritage - alongside environmental protection, infrastructure development, and civil services for the community. Cultural resources management remains integral to operations on tribal lands. The organisation is guided by the principle of Yawa', which emphasises acting on one's beliefs, and extends this philosophy through philanthropy and community partnerships throughout the Inland Empire and Indian Country.
Employment at the San Manuel Band of Mission Indians involves contributing to governance, cultural preservation, community development, and the protection of tribal sovereignty. The organisation values collaborative work and describes its mission as preserving a living legacy shaped by generations of resilience, with an emphasis on accountability and community well-being.
