The three were part of a group at The Cure International Hospital in Kabul. Dr. Umanos was a pediatrician helping Afghan children wounded in the war and training a new generation of doctors. He worked at the Lawndale Christian Health Center on Chicago’s West Side for 16 years before he and his wife, Jan Schuitema, moved to Afghanistan.
