When natural disasters or public health crises strike, emergency medical services and public health agencies often struggle to meet the health needs of their communities. To address this, Optum Serve, the federal health services division of Optum and UnitedHealth Group, helps clients improve the overall health and well-being of individuals and communities by promoting healthy behaviors, addressing risk factors for disease, and addressing the underlying social, economic and environmental factors that influence health. Additionally, Optum Serve works with clients to ensure they are ready to respond to and recover from a public health crisis or disaster.
