Pediatric Developmental-Behavioral & Mental Health

Understanding Developmental-Behavioral Pediatrics

Developmental-Behavioral Pediatrics is a pediatric specialty that focuses on evaluating, diagnosing, and treating developmental, behavioral, learning, and mental health concerns that affect children and adolescents. Our goal is to help each child reach their fullest potential through individualized, evidence-based care that recognizes their unique strengths, challenges, and needs. This is accomplished within the context of the child’s family and the other important people who support the child’s growth and success. We aim to promote meaningful changes for individuals and families that are consistent with their cultural beliefs, practices, and values in order to improve quality of life.

Our Approach

Every child and family is unique. We believe meaningful progress begins with understanding each child’s individual strengths, challenges, and goals.

Treatment plans are individualized, clearly defined, and developed in partnership with families. We establish measurable goals, monitor progress, and continually adjust recommendations as each child’s needs evolve. Collaboration with families, schools, health care providers, and community partners is central to our physician-led model of care.

Many children make excellent progress without medication. When medication is indicated, recommendations are made thoughtfully and collaboratively, taking into account each child’s needs, medical history, and family values.
