Dr. Duvivier provides family pediatric care for Nassau County and the surrounding areas. Yes, we welcome new patients, and we accept most insurance plans. Give the office a call, or reach out online and we'll call you back.
From newborn checkups to young adulthood, our team is here for the everyday and the unexpected.
Routine checkups that track growth and milestones at every age.
Same-day appointments when our patients aren't feeling well.
On-schedule immunizations following the latest guidelines.
Prescriptions electronically sent to your pharmacist of choice.
Friendly guidance on feeding, sleep and healthy habits.

Dr. Duvivier cares for patients from their very first checkup onward. The same doctor who saw your child at two weeks old is the one that's seeing them up until young adulthood.
A solo practice means you see the same trusted team each and every visit.
For me, being a pediatrician in New York for more than a decade is both a calling and a privilege. My journey in medicine began at Adelphi University, where I earned my B.S., and continued at the New York College of Osteopathic Medicine, where I received my D.O. degree and embraced a whole-person, compassionate approach to care.
Caring for children in New York has let me form meaningful, lasting relationships with families who feel like an extension of my own. I have had the joy of watching my young patients grow from infancy to young adulthood. Every milestone reminds me why I chose pediatrics: to support, to guide, and to advocate for the health and well-being of every patient who walks through my door.
My commitment is simple: thoughtful, culturally attuned, family-centered care that honors both the science of medicine and the humanity of the families I serve. After more than ten years, New York is not just where I practice. It's home.
