Reinforcing Our Community
MRC GEM is an all-volunteer nonprofit whose mission is to augment community health operations during large-scale emergencies, aid response to pressing health care needs, and improve community emergency preparedness. We serve Georgia’s Gwinnett, Newton, and Rockdale Counties, a highly diverse population of well over 1.2 million people.
Anyone can volunteer with us, regardless of prior experience or training. While many of our volunteers have healthcare backgrounds, two-thirds of us do not. When disaster strikes, all kinds of volunteers are needed. We provide monthly training opportunities free to our volunteers.
COVID is a perfect example of when our help was needed: our volunteers provided over 17,000 hours of support, helping with 375,000 vaccinations and tests. We’ve assisted with hurricane evacuation shelters, TB testing, distributing Narcan kits, providing first aid stations at public events, among many other functions. We have over 1,300 volunteers who either have an active healthcare license or a current background check. Our work has received awards and special recognition from GNR Public Health, the Gwinnett County Commission, the Georgia State Legislature, FEMA, and the U.S. Surgeon General.
We accomplish all this with NO paid staff – we’re ALL volunteers, including our entire management team. We depend on grants, individual donations, and corporate concessions to enable ongoing recruitment and training, so we’ll have the trained volunteers needed to respond quickly when needed to disasters and other emergencies.
