It was while in Uganda as a young and idealistic physician that Dr. Richard Heinzl finally heard his true calling: to set up a chapter of Doctors Without Borders in his native Canada. As a prerequisite to fulfilling his Médecins Sans Frontières dream, Dr. Heinzl was sent to a war-ravaged town in Cambodia to work a year in the field. Cambodia Calling is this young doctor's harrowing personal story of setback and accomplishment in the dangerous and inhospitable environment of a remote Cambodian village. His compelling narrative details how he confronted his own illness and self-doubt, as well as the reality of treating those who could not be saved.
