World-class services for you and the ones you love
We provide exceptional patient care through our dedicated staff and robust programs and services, all while pioneering leading research and educating the next generation of medical professionals.


Welcome to the Division of Pulmonary, Critical Care and Sleep Medicine. We’re a dynamic, integral part of the Department of Medicine with deep commitment to all three elements of the academic medicine mission: clinical care, education and research. As part of Northwell Health, one of the nation’s largest health systems, we have access to unparalleled resources, including a large, diverse population with many types of conditions and disorders, allowing us to build remarkably broad expertise.

Our division first opened its doors in the 1980s with one faculty member; since then it has seen exponential growth to become a faculty of over 35 dedicated academic physicians. Our faculty is nationally and internationally recognized for its expertise in pulmonary, critical care and sleep medicine, and we boast innovative clinical research and graduate medical education programs.

Our pulmonary medicine outpatient services span the full range of lung diseases, whether common or rare, simple or complex.  We have also developed subspecialty programs in pulmonary hypertension, asthma, critical care, cystic fibrosis, non-CF bronchiectasis, non-tuberculous mycobacterial diseases, interventional pulmonary medicine, pulmonary rehabilitation and sleep medicine. Our faculty serves as a resource for primary care providers, as well as other pulmonary physicians seeking help with more complex cases.
