With a master's degree in Clinical Practices (psychology), Lydia Burdick's career has been in human resources. Since 1993, she has been a consultant at an international outplacement firm. Lydia wrote The Sunshine on My Face in the course of caring for her mother who was diagnosed with Alzheimer's disease. "One of my greatest pleasures," she says, "was sitting together with my mother and hearing her read the words from this book when she had otherwise stopped speaking almost entirely."
