Modern Healthcare's 1991 Up and Comers, the fifth annual group, are scattered all over the map, from Boston to the Bay Area, from Flint, Mich., to El Paso, Texas. They work in managed care, associations and specialty hospitals; one even administers the office that cares for members of Congress. At least two are "healthcare brats" whose fathers managed hospitals. One spent time working in a salmon cannery; another was a Peace Corps volunteer in Swaziland. Despite their differences, they share many common traits. They are bright, committed and know how to motivate and involve others. Maura Loughlin Carley, an area administrator for Kaiser Permanente Foundation Health Plans, put it best when she said her goal is to "hire the best people, develop them and keep them happy." They're also committed to seeking new ways to improve healthcare delivery. As Kevin Potter said, "What keeps me humble is that there's so much that I'm learning every day." Each of these emerging leaders is making a mark on the healthcare industry. They were chosen from a field of almost 50 candidates, all 40 or younger, compiled by the editorial staff of Modern Healthcare and readers.
