Coastside CERT began sending Coronavirus information to our membership and posting important national and local COVID-19 links on our website in January, 2020. We sent our first membership-wide local Coronavirus Preparedness message on March 7, to which Scott Morrow, MD, MPH San Mateo County Public Health Officer replied, "This is remarkably well conceived and written."

After Shelter In Place orders began March 13, 2020, Chief David Cosgrave began a series of weekly newsletters as a calm, trusted source of reliable information, guidance, and the occasional much-needed smile for Coastside CERT membership. The weekly COVID-19 newsletters continued until Shelter In Place on June 17, 2020. The Chief has continued to communicate via newsletters and for that reason we will carry the whole series, indexed by topic for easy reference, under a separate Newsletters heading.
