About Us

The California Emergency Services Association (CESA) is a non-profit professional organization dedicated to the promotion of mutual support and cooperation across disciplines. We work to support our members in preparing for natural and human caused disasters and public emergencies.

Our dynamic organization includes academic institutions, representatives from government agencies, utilities, and businesses of all types, nonprofits and faith-based organizations, as well as media and elected officials.


Together, we share common goals as the leaders and practitioners in Preparedness, Response, Recovery, Mitigation, and Protection in California. Our Association includes seasoned professionals, total novices and world class experts, as well as part-time, full-time, paid staff and volunteers.

The CESA Chapters

The Chapters of CESA follow the California Governor’s Office of Emergency Services Administrative Regions. Each member is assigned a Chapter at the time of membership registration, typically based off their address or their area of responsibilities. Each Chapter offers leadership development opportunities through committee and board positions.

CESA welcomes everyone who is passionate about emergency management in California. Whether someone calls it Emergency Management, Business Continuity, or Disaster Preparedness, we all are in the business of preparing for, responding to, recovering from, and mitigating everything from planned events to disasters. CESA is a place for you to gain that knowledge and share your experience.
