ity. Tumpati had a Hindu father and a Christian mother, an unusual combination in that part of India, and they had raised him Chris- tian. His maternal grandmother had converted after his mother suffered a grave childhood illness; the family believed she had been cured after a villager suggested the grandmother pray to Jesus. Faith would lead to providence in Tumpati's own life, too: At the suggestion of a local pastor, Tumpati applied to a children's board- ing school, several villages away, run by an Indian American mis- sionary physician from Pennsylvania. From there, Tumpati's intellectual abilities and relentless work ethic carried him to a top- flight Indian medical school, postgraduate work in Norway, and an internal medicine residency at Abington Memorial in the United States. That he landed in the state from which his own missionary childhood teacher hailed only confirmed for Tumpati the power of God's works.

Now, though, he was fully trained, and trying to find his way in the American workforce. His son had been born the year before, and with another baby on the way he and his wife decided she would quit her job as a computer programmer and stay home with the kids.

Straight out of residency he took on two part-time medical jobs, one as an associate doctor at an internal medicine clinic started by a friend, the other at a com- pany where he reviewed drug test results from patients around the country.

The site grew to over six thousand registered users. He'd also created a site called WikiMD.org, a Wikipedia-like medical encyclopedia maintained by volunteers. So
