As a plastic surgeon, [Geoff] Williams could live in a sprawling house, cruise in a snazzy sports car and wear custom-made shoes instead of the $5 pair he snagged at the thrift store a few years back. Instead he spends his money on hundreds of strangers, half a world away. Grown men with rope-like tumors engulfing their eyes, nose, lips. Teenage girls with heads cocked permanently to one side because of burn-tightened skin. But mostly children - with faces split up the middle like a half-open zipper. Williams invests in faces. As he worked and taught in wealthy hospitals, his mind was preoccupied with thoughts of the hundreds of desperate mothers in Vietnam who had swarmed him during a volunteer training trip, thrusting their deformed babies at him and begging for help. Only 20 babies were treated that trip; about 180 were sent away. Leaving, looking down at those lights, I knew these mothers were going home with total disappointment," Williams recalls. "I remember making a promise to myself then, to those mothers: I may not be able to find you, but I'll find someone like you. I'll come back. I'll do more." Several months later, he took another volunteer trip, this time to India. "I thought I'd do it a couple of times and get it out of my system. After about a year, it just hit me - it would not be easy to stop doing it." He took a leave of absence from the University of Texas in 2003 to immerse himself in treating the forgotten patients in developing countries. He never went back.
