In August 2011, I traveled with a medical aid expedition to Huancavelica, Peru. High in the Andes, it’s an area blessed by rugged beauty and plagued by poverty. I was along to document the mission, a collaborative effort among doctors from Peru and the United States that not just brought medical help to the region but also brought people from remote villages to the area’s major hospital. For some patients, the doctors could offer a simple fix and reassurance that everything would be okay; for others, they provided life-altering surgery.
