Don Bartletti grew up in a rural part of San Diego County, and his interest in Mexico and migration dates back to his childhood, when he first took notice of the migrant farmworkers in his community.
For more three decades, he has chronicled the people of Mexico and Central America and the struggles they face.
His interest in photography was sparked during his service in Vietnam. Bartletti, an Army infantry officer, bought a Nikon F camera to photograph the war-torn country and its people.
"I'd taken one photography class in college," he said. "I was fascinated by the people and landscape of Vietnam. I shot more pictures than bullets."
