The Pediatrics department at Mount Sinai Doctors-Long Island  includes six physicians and one certified pediatric nurse practitioner who is also an IBLCE Lactation Consultant. One of our physicians specializes in pediatric gastroenterology. We are committed to providing quality care for infants, children and adolescents. Our practice is open 7 days a week for acute care.

In case of illness and depending on the urgency of the problem, an appointment may be obtained with one of the pediatricians who is available that day. All members of the department have access to the electronic medical records and communicate with each other regarding the care of patients within the group.

Most parents select one of our pediatricians whom their children see for routine visits. An ongoing relationship is established as the physician becomes familiar with the needs of the child and the family. All patients are seen by appointment only.

Newborn Care

Newborns are cared for daily by one of the pediatricians in the nursery at Huntington Hospital. When the need arises, newborns are also seen by a neonatologist from the Huntington Hospital affiliated Division of Neonatal Medicine of North Shore University Hospital.

Early follow-up of newborns in the office followed by routine visits at prescribed intervals is encouraged. Goals of the visits include:

  • Physical examination
  • Growth monitoring
  • Neuro-developmental assessment
  • Administration of vaccines for prevention of infectious diseases
  • Guidance and advice on topics such as nutrition and behavior issues

Lactation Consultation and Services

We provide lactation support and consultation by appointment. Our goal is to provide care, education, and counseling for mothers and families to help create a positive breastfeeding and bonding experience for mother and baby.

We provide resources to help families reach their own breastfeeding goals while striving to help families meet the American Academy of Pediatrics (AAP) recommendations. The AAP endorses, “exclusive breastfeeding for about 6 months, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant.”


Immunizations against infectious diseases are a critical part of preventive care and are required for school entry. We encourage all patients to be fully immunized. For more information on vaccination, visit the Centers for Disease Control and Prevention.
