About Us

Girl talking to counselor

Pediatric psychology addresses physical, cognitive, social, and emotional functioning and development as they relate to health and illness issues in children, adolescents, and families.

We explore the interrelationship between the psychological and physical well-being of children, adolescents, and families, including psychosocial and developmental factors contributing to the etiology, course, treatment, and outcome of pediatric conditions.
