The Most Good - For the Most People - In the Shortest Amount of Time Community Emergency Response Team (CERT) members are volunteer first responders trained to assist their families, neighborhoods and communities following a disaster or emergency where professional responders are not immediately available to help.

The UofN-CERT has been active locally and frequently mobilized by Hawaii County Civil Defense since 2010.
