Jonathan B. Jassey, DO




 Dr. Jonathan Jassey has been a private pediatrician at Bellmore Merrick Medical since 2007 and is thrilled to treat the community in which he was raised. Dr. Jassey takes a lot of pride in treating the "colicky" infant and getting a baby sleeping through the night at a young age.

He is the co-author of "The Newborn Sleep Book," based on his tremendous success with his methods. As a reflection of his superior bedside manner and the impact he has made in the health of his patients, Dr. Jassey has received the Patients’ Choice Award for three consecutive years, which is given to practitioners who have gotten near perfect scores by votes from patients, as well as the Compassionate Doctor Recognition Award. He is board certified by the American Academy of Pediatrics.  


Dr. Jassey graduated from the New York College of Osteopathic Medicine. He also completed his residency in pediatrics at Winthrop University Hospital.

A Word From Jonathan B. Jassey, DO

I am extremely excited to be involved with Verywell and help them provide accurate medical content to its readers, especially in the pediatric space. Too much information online is not factual and to have a reliable source of medical information that is backed up from medical professionals is paramount to anyone looking, especially for kids.
