In Contra Costa County, people experiencing a behavioral health emergency often do not get the care and help they need. There is not currently an appropriate, reliable and comprehensive response system.

Contra Costa Health Services (CCHS) is working to address the unmet behavioral health needs in Contra Costa County through the A3 initiative.

A3 provides timely and appropriate behavioral health crisis services to Anyone in Contra Costa County Anywhere at Anytime. Currently, A3 operates five days a week during specific hours. As we expand these services over the next year, A3 will provide 24/7 emergency behavioral health support.
