Marin County has two medical volunteer (unpaid) teams: 1) the Marin County "Surge" Unit and 2) the Marin Medical Reserve Corps.  

MARIN MEDICAL RESERVE CORPS:  These are the first volunteers deployed by the County of Marin in a medical emergency. Volunteers are engaged and active in unit preparedness and response activities and have increased training and participation requirements. At this time, MMRC is closed to new volunteers. We are onboarding all volunteering into our Marin County “Surge” Unit (description to left) due to relaxed training and participation requirements during COVID-19 activation.

MARIN COUNTY "SURGE" UNIT: These volunteers are on a reserve list of licensed healthcare volunteers and can be called to back up the Marin Medical Reserve Corps (MMRC) or Marin County Public Health during emergencies related to large-scale, catastrophic events. Volunteers receive just-in-time training prior to deployment. During COVID-19, all new volunteers will be on-boarded into the Marin County Unit. In the future they will be offered an opportunity to join the MMRC.  


Registration in the DHV system does not guarantee a volunteer placement or deployment. Volunteers are not to self-deploy and must be scheduled and confirmed through a representative from the County of Marin. Steps to deploy: 

  1. Receive Disaster Healthcare message from the County of Marin requesting availability. 
  2. Receive assignment confirmation from a County of Marin employee. Volunteers are not to self-deploy.
  3. Complete Disaster Service Worker Oath & other paperwork deemed necessary for the assignment. 
  4. Receive just-in-time training
