Joseph F. Hagan, MD, FAAP

Dr. Hagan started this practice, and after more than 40 years he retired at the end of 2021.

He is beloved by his many patients, whom he still delights in seeing in the community.  Patient care was always his priority.  Additionally, he was heavily committed to children’s advocacy and improving pediatric health care on the local and national levels.

Dr. Hagan is the editor of The Bright Futures Guidelines for Health Supervision of Infants, Children, and Adolescents. This manual is the nationally designated standard for pediatrics preventive care. He has also contributed to four major pediatrics text books and has published several articles in pediatric journals.

Dr. Hagan was highly involved in the American Academy of Pediatrics, as the former President of the Vermont Chapter of the AAP, the former Chairperson of the Committee on the Psychosocial Aspects of Child and Family Health, and the former Chairperson of the AAP’s Committee on Terrorism.

Dr. Hagan also served as the Chairperson of the Vermont Citizens Advisory Board helping the Department of Children and Families care for child abuse victims.

Dr. Hagan was committed to teaching medical students, residents, and his fellow clinicians.  Many of us in pediatrics have a great deal to thank him for.  We are honored to be continuing the practice he built.

Dr. Hagan’s pride and joy are his wife, four children, and five grandchildren.  He lives in Burlington, and would be delighted if you would say hello when you see him.

Leaders in Pediatric Medicine

From editing the Bright Futures Guidelines for general pediatrics, to leading the Pediatric Medical Home movement, to leadership in the American Academy of Pediatrics, to protecting and enabling athletes through the Kelly Brush Foundation, to teaching future pediatricians, we strive to advance pediatrics both in our office and in the world.

We believe in a holistic approach to a child’s care that includes mental and physical health as well as that child’s support network. We have a collaborative approach that coordinates a child’s care into a unified effort.
