Public Health Reserve Corps

Thanks for your interest in the Public Health Reserve Corps!

The Public Health Reserve Corps (PHRC) is a nationally-recognized Medical Reserve Corps donating thousands of hours of services each year to promote the health and wellbeing of King County residents. Changing circumstances are leading Public Health – Seattle & King County to reshape the PHRC into a leaner, more focused response organization going forward.

Interested in joining the Public Health Reserve Corps? The PHRC is temporarily closed to new members. Recruitment of new volunteers will restart in late 2020.

See information about significant program changes which will impact all members:

The PHRC is undergoing significant changes. Public Health – Seattle & King County is reshaping the Public Health Reserve Corps to improve its ability to deliver top quality compassionate care to people living homeless, rapidly mobilize emergency response capabilities, and offer more and richer participation opportunities for members. This new direction is influenced by changes in Public Health's emergency response strategies, changes in hazards facing King County, shifting county demographics, reductions in federal funds to support Medical Reserve Corps, feedback on annual volunteer surveys, and analysis of past PHRC responses.

Unfortunately, these changes also mean the Public Health Reserve Corps will no longer train for and respond to certain missions it formerly fulfilled.

Mission Enhance Public Health's ability to respond to public health emergencies or disasters to limit injury, illness, suffering and death Bridges gaps in access to care prior to and during emergencies by delivering compassionate care to King County's most vulnerable residents in non-traditional settings like tiny home villages, shelters, health fairs, and community centers.
Hazards preparing for: All hazards Earthquakes, disease outbreaks, severe weather, mass fatality incidents
Capabilities which can be mobilized: Radiological incident response, public information, mass dispensing, vaccinations, first aid through acute care, disaster behavioral health, health education, redundant communications, interpretation, environmental health, and more. Limited range of capabilities to support the above scenarios such as health assessments and triage, vaccinations, mental health, disease investigation, and health education.
Membership Open to anyone. Open to medical and non-medical volunteers with specific credentials and skills which support the more limited range of response capabilities PHRC will now provide.
Participation requirements: Volunteer Orientation, FEMA ICS 100 & 700. Greater required trainings assure every member is skilled serving people living homeless and those with functional and access needs. Members must participate in at least one event each year.
Readiness to respond: Response plans assumed that up to 30% of registered volunteers could be ready to respond within 72 hours of notification; real world response rates were far lower. Goal for 75% of volunteers able to respond within 24 hours.
What this means for current volunteers:
