Our Primary mission is to provide the Federal, State and Local Governments and commercial customers with healthcare staffing, technical and support services. Posterity Group’s service delivery philosophy is based on four core methodologies; Customer First, Quality Management, Project Management, IT and Health Informatics, which permeates every service offering.

Posterity was formed in 2007, and our mission statement is: “We listen to our customers’ needs, and then, simply exceed their expectations!” Our creative team members are motivated to deliver value and inventive ideas. We do what’s right, and act with integrity on behalf of our customers.

Posterity’s story begins with our CEO, Radcliffe Antoine’s vision to duplicate the structure, teamwork, and comradery of the military, while providing beneficial services to military members and their dependents.

He is a decorated Army-trained Physician Assistant and Clinical Perfusionist, and former key member of the elite Open-Heart Surgical Team at VA Walter Reed National Military Medical Center.

President's Message

Welcome to the Posterity Family

Posterity was founded on the dream of building an organization that embodied the principles of leading by example, integrity in all that we do, and fairness in the treatment of all.

We regard team-members as our internal customer and our most valuable asset, and commit ourselves to providing exceptional customer service and prompt response to your needs. As an organization, Posterity is a continuation of my service to this country and the men and women that wear the uniform. I am proud to lead an organization that is committed to excellence.

Together, we will live up to our motto,
“Esse quam videri” – To be rather than to seem.

-Cliff Antoine
