During her hectic work week, TAMMI RUNZLER manages a staff of 43 sales and services professionals in her job as senior vice president of convention sales and services for Visit Orlando, the destination marketing organization tasked with booking the city's mammoth convention center and helping to fill the popular meeting destination's 116,000 hotel rooms.

But about every six weeks, and on every one of her paid days off, Runzler spends time in Haiti with “her children,” many orphaned by the devastating January 2010 earthquake. She is so committed to the cause of helping the world's poorest children, in particular Haiti's most vulnerable, that she, along with two friends with a common interest in charitable work, have started a charitable organization, My Neighbor's Children.
