Godwin Godfrey, pediatric heart surgeon —
Meanwhile at Bugando Medical Center in Mwanza, north Tanzania, Godwin Godfrey, who hails from the small town of Moshi, in the foothills of Mount Kilimanjaro, is also fighting to fix the hearts of children. As his country's only qualified pediatric heart surgeon, he is constantly battling inconsistent electricity, lack of equipment and a shortage of trained medics while on his quest to help some of the 300 suffering children, who await surgery at Tanzania's largest teaching hospital.
"Somebody has to do something -- and this is one of the reasons I came back," said Godfrey, who returned to Tanzania after five years work experience in Tel Aviv, Israel.
