The California Governor's Office of Emergency Services (Cal OES) is the State of California's lead agency for emergency management and homeland security. Its mission is to protect lives and property by effectively preparing for, preventing, responding to, and recovering from all threats, crimes, hazards, and emergencies. Cal OES coordinates disaster response activities statewide, works with local governments to enhance emergency preparedness, manages federal disaster aid, and provides training and resources. It was formed in 2013, consolidating the former California Emergency Management Agency (Cal EMA) and the Office of Homeland Security, building on a legacy of state emergency services dating back to 1950.
The headquarters serves as the primary command and control center, housing the State Operations Center (SOC). It facilitates statewide emergency planning, response coordination, recovery efforts, and administrative functions.
The most notable feature is the state-of-the-art State Operations Center (SOC), a technologically advanced facility for managing and coordinating emergency response. The campus also includes training facilities and specialized equipment.
The work culture at Cal OES is mission-driven, characterized by dedication, collaboration, and a strong sense of public service. During emergency activations, the environment can be fast-paced and high-stress, requiring resilience and adaptability.
The Mather headquarters is critical as the nerve center for California's emergency management infrastructure. It enables seamless coordination among local, state, federal, and tribal partners during crises.
As a state agency, Cal OES's primary focus is on serving the State of California. It does not maintain global offices in the corporate sense. However, Cal OES collaborates extensively with federal partners like FEMA and may engage with international entities or provide/receive mutual aid during catastrophic disasters or for knowledge exchange in emergency management best practices. Its 'global' interactions are typically related to large-scale disaster response, cross-border cooperation (e.g., with Mexico), or participation in international emergency management forums.
