Nearly 40 years ago, Dianne Walker walked away from her job as a staff child psychologist at Boston University Hospital to become a tap dancer. This month, "Lady Di" will be honored by her peers and tap family at The Big Apple Tap Festival in New York City. "I feel a tremendous sense of accomplishment," Walker says. "Deep down inside I want to scream with joy because I feel so excited about what I—and we as a community—have been able to accomplish over these years. I feel really good about where we are as a tap-dance community."
