Our History

At Pediatric Associates of NYC we have been taking care of the children of New York City since 1948.  Collectively our physicians represent many years of advanced training and experience.  We continue to maintain a model of traditional care in which we firmly believe that pediatricians are the best equipped to take care of all aspects of your child's care.  Whether it is answering a simple question on the phone or providing and coordinating care to children with complex medical needs, we are always available.  We actively encourage and teach healthy child rearing practices, provide counseling for concerns big and small, and deliver expert and compassionate care for children and their families from birth through adolescence.
