The Pediatric Pulmonary Division at Stony Brook Children's provides outstanding, family-centered, state-of-the-art care with compassion.

At Stony Brook Children's Hospital, we are committed to providing the highest quality of care to the children of Suffolk County with pulmonary conditions. As the only academic health center in the county, we have the resouces and expertise to diagnose, treat, and manage a wide range of respiratory disorders in children of all ages.

Pediatric respiratory diseases come in many forms — from cystic fibrosis and sleep apnea to asthma, allergies, and chronic lung disease — each needing a highly specialized approach to treatment. Through specialty centers and clinics, as well as with an active physician practice, the Pediatric Pulmonary Division at Stony Brook Children's provides expertise and a wide range of clinical services to appropriately and effectively address respiratory disease in infants, children, and adolescents.

Our accredited pediatric Sleep Center evaluates and diagnoses pediatric sleep disorders including obstructive sleep apnea, respiratory disorders, insomnia, parasomnias such as night terrors and sleepwalking, and behavioral problems relating to sleep. 

The Cystic Fibrosis Center at Stony Brook Children's has been accredited by the Cystic Fibrosis Foundation since 1990. The center oversees the care of many patients, from birth through adulthood, and is one of only 130 centers accredited by the Cystic Fibrosis Foundation.
