Meet The Team

Dr. Jonathan Jassey

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.

Dr. Sharon Somekh



Hi! I’m Dr. Sharon.  I’m a board-certified pediatrician born and raised in Queens, NY. I attended Binghamton University and received my medical degree and pediatric medical training from Upstate Medical University in Syracuse, NY. 

Being a mom to 4 daughters has greatly influenced my practice of medicine over the years.  My challenges breastfeeding my first 2 daughters inspired me to become an International Board-Certified Lactation consultant to assist moms in reaching their personal breastfeeding goals.  My experiences as a mom and pediatrician led me to coach parents on the many challenges faced raising children of all ages, with a primary focus on relieving parental anxiety and helping parents truly enjoy this time in their lives, as every stage of parenting brings a unique experience that shapes us as human beings. 

The past few years have offered me the opportunity to practice in local homes, getting to know families on a deeply personal level. Additionally, with the decline of the pandemic, I have been fortunate to explore an additional specialty as I’ve begun to practice Aesthetic Medicine. 

In my free time I enjoy curling up on the couch to watch movies with the girls, playing tennis or boxing, and going out with friends. 

As a local mom in Roslyn, I truly understand how raising children in our wonderful community can simultaneously be both the most challenging, yet most fulfilling experience. I am excited to continue caring for your children in a medical environment that fosters a more intimate relationship unique to Concierge Pediatrics.
