The Partnership for Public Service honored the nine winners of this year’s Samuel J. Heyman Service to America Medals at a Washington, D.C. gala Thursday evening.

This video features Charles Scoville of Walter Reed National Military Medical Center, winner of the National Security & International Affairs Medal. Scoville enables combat amputees to lead active lives and potentially return to duty through an internationally recognized rehabilitation program that uses a novel sports medicine approach. Some 1,450 injured service members who have been through the program have gone on to complete triathlons, climb Mt. Everest and compete in gymnastics, skiing, rowing and other sports.

The medals, popularly known as “Sammies,” are awarded to public servants who are making high-impact contributions to the health, safety and well-being of Americans.
