Talk about longevity: Robert Drisner, 65, is stepping down after 34 years with Community Memorial Hospital in Menomonee Falls, Wis. He started as president of the hospital in 1969 and added the title of president of parent Community Health Care Services in 1988. He stepped down from the hospital post in 2000, when he was replaced by William Bestor, who also will succeed Drisner at the parent company. Under Drisner, the hospital grew from a 61-bed facility to a 237-bed regional medical center. "What began as a learning experience became much more," Drisner said. "I thought I'd help Community Memorial get established. Instead, I fell in love with the community and the vision we put together for our hospital." ...
