Founding Pediatrician

Hi! I’m Dr. Jonathan Jassey.  I have been a board certified private pediatrician since 2007 and graduated from the New York College of Osteopathic Medicine. I completed my residency in pediatrics at Winthrop University Hospital. 

Treating countless families over the years, I have been fortunate to develop expertise in all ages from newborn to late adolescence.  My experience caring for young children has allowed me to help many families through common challenges such as infant colic and sleep concerns, which can be incredibly daunting to deal with as a parent. I am the co-author of “The Newborn Sleep Book”, based on tremendous success with my methods and my commitment to helping parents and children get some much needed sleep! As we all know, that is only the beginning of many of our parenting journeys and as we have seen over the past few years mental health has become an increasingly important aspect of pediatric care.  My interests and experience in treating children with autism, ADHD, anxiety, depression, and OCD allow me to provide families medical care that addresses the whole child and family.  

It has been my great honor to have received the Patients’ Choice Award for three consecutive years, as well as the Compassionate Doctor Recognition Award, and I am humbled by my patients’ recognition of the impact I have made on their health.

In my free time, I enjoy spending time with my wife, Suzanne, and 3 daughters, Charli, Camryn and Harper. I love coaching my girls in basketball, soccer and softball. My hobbies and interests include playing basketball and being a diehard sports fan of the Mets, Giants, Knicks and Islanders. I consider myself a foodie and love exploring new restaurants.  

I started Concierge Pediatrics to bring old school medicine back to modern day times, with me being an extension of your family.  I am so excited to give all of myself to treating patients and giving the appropriate time needed to treating all of patients medical needs.  There is nothing better as a Pediatrician than seeing my patients as fine young adults after having cared for them since infancy.  I can’t wait to share this journey with each and every one of you.
