SWYC – Who We Are

ellen perrin

Ellen Perrin, MD
Professor, Division of Developmental-Behavioral Pediatrics, Tufts Medical Center, Tufts University School of Medicine, Boston, MA.

Dr. Perrin’s career has blended her background and interest in developmental psychology with her passion to improve the lives of children and their parents. As President of the Society for Developmental-Behavioral Pediatrics, she was instrumental in gaining formal subspecialty status for Developmental-Behavioral Pediatrics through the American Board of Medical Specialties and was the first Chair of the American Board of Pediatrics’ sub-board on Developmental-Behavioral Pediatrics. She is committed to helping primary care pediatricians to address children’s optimal development and behavior most effectively. In her clinical work and research, she has worked with pediatricians in the care of children with chronic physical health conditions and a wide range of developmental-behavioral difficulties. In addition, she has been committed to advocacy for teens and parents who are gay or lesbian, and gender nonconforming young children. Recognizing the importance of early identification and intervention in developmental-behavioral problems and a need for a different kind of screening strategy, she worked with Dr. Chris Sheldrick to develop the Survey of Well-being of Young Children (SWYC).
