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

Lakeside Pediatrics strives to provide the highest quality pediatric care to our families.  We are a small, private practice located in Burlington.  Founded in 1991, our clinicians have included the editor of the national guidelines for general pediatrics, a nationally renowned advocate of the Medical Home movement, and a champion of spinal cord injury prevention and athlete support through the Kelly Brush Foundation.  We teach medical students, nursing students, and pediatrics residents in our office and at the hospital.  More than anything, though, we are focused on our patients.
Every day when we open exam room doors to see our patients, we are stepping in to see old friends.  We often know our patients from fetal life through young adulthood.  We know that caring for them means working as a team with them, their families, and their support networks.  It means supporting their cultural identities.  It means focusing as much on their mental health as their physical health.
We have tremendous gratitude to our families for allowing us to care for their childrens’ health while on their journeys into adulthood.
