Developmental and Behavioral Pediatrics Fellowship


Program Overview

The Developmental-Behavioral Pediatric Training Program is sponsored by the University of Colorado School of Medicine Department of Pediatrics and Children's Hospital Colorado (Children's Colorado). This is a three-year fellowship program approved by the Pediatric Residency Review Committee of the Accreditation Council for Graduate Medical Education. The program is directed by Abigail S Angulo, MD, MPH, and is based at the University of Colorado School of Medicine (CU SOM) and Children's Hospital Colorado, both of which opened entirely new facilities in 2007 on one large medical campus in Aurora, Colorado - Anschutz Medical Campus. Fellows are supervised by faculty within the Section of Developmental Pediatrics, the Neuroscience Institute at Children’s Colorado, and the Department of Pediatrics at CU SOM.

Program Aims

  • To prepare subspecialty pediatricians to provide patient-centered, comprehensive care of children and young patients with neurodevelopmental disabilities and associated behavioral problems and their families with a focus on promoting patient safety and quality improvement and developing excellent communication skills.
  • To provide outstanding opportunities in basic science, translational, clinical, educational research and quality improvement methodology that prepare fellows for successful careers in academic pediatrics.
  • To teach trainees strategies to maintain wellness (of self and others), to build resilience, and to minimize burnout.
  • To build and maintain an infrastructure to recruit diverse fellows and provide an inclusive learning environment that promotes and celebrates differences.

Program Requirements

To qualify for the program one must have completed core training in Pediatrics (three years). We pay particularly close attention to the commitment to scholarship, education, research, and clinical excellence, as well as to the letters of recommendation and career performance records. Trainees will be funded at the CU SOM Department of Pediatrics PL 4-6 salary levels, including an excellent benefits package. Annual vacation, educational and sick leave, health, life disability and malpractice insurance are included in the benefits package.


Our Training Program provides all of the clinical experience necessary to be eligible for certification by the Sub-Board in Developmental-Behavioral Pediatrics. Clinical experiences are broad and emphasize comprehensive assessments and management of a wide range of developmental and behavioral disorders, based on evidence-based practice. All trainees participate fully in the structured activities of the program, including:

  • Interdisciplinary developmental assessments
  • Individual consultations and long-term management

Diversity / Equity / Inclusion


We are committed to creating a diverse environment for students, residents, fellows, and faculty. We believe that an environment of inclusiveness and respect promotes excellence and that a setting where diversity is valued leads to the training of physicians who are prepared to practice culturally effective medicine and meet the needs of the various populations we serve. Visit our Diversity, Equity, and Inclusion webpage for more....

Well-Being / Resilience

Be well

By embracing wellness and improving personal resiliency, physicians can reconnect with the meaning of their work and fend off stress. Reducing or eliminating burnout also has practical implications for the entire department such as improving patient safety, student advancement, and the overall campus environment.
