(MONEY Magazine) – As a woman with deep ties to her native Sudan and as a Western-trained doctor, "I belong to two teams," says Nawal Nour. She successfully brings those worlds together at Brigham and Women's Hospital in Boston. There, she has a following among African immigrants and refugees who've undergone female circumcision and trust her to provide nonjudgmental care. ("Western doctors are often shocked and unsure," says Nour, 38, who was spared the procedure by her progressive father.) She led focus groups, and then got the hospital to underwrite the African Women's Health Center in 1999. The center handles 800 patient visits a year, mostly for free. Nour won a $500,000 MacArthur Foundation fellowship last year--and now hopes to support clinics in Africa. --E.M.
