Reinforcing Our Community
MRC GEM is the Georgia East Metro Health District Medical Reserve Corps, Inc. We are a non-profit organization serving the health and emergency preparedness needs of Georgia’s Gwinnett, Newton, and Rockdale Counties. We work closely with local health departments, emergency managers, and homeland security to augment and scale up their responses.
We are not a military organization, though our name might sound like one. We are a top-to-bottom volunteer organization. MRC GEM provides free monthly programs of interest to our volunteers, helping them learn to prevent and deal with emergencies affecting themselves, their families, and their communities. We have no ranks per se and are happy for any member to step up and help manage MRC GEM – just ask how you can help!
