  • Director,
    Moyamoya Center
  • Professor of Neurosurgery,

David Langer, MD is the chair of neurosurgery at Lenox Hill Hospital. Internationally recognized as an expert in cerebral revascularization and cerebral aneurysms, his work focuses on diseases of the brain vessels. Dr. Langer's work has been featured in numerous peer-reviewed publications and he has spoken nationally and internationally on vascular disorders such as aneurysms and arteriovenous malformations (AVMs) of the brain. He is one of the few cerebral bypass surgeons in the country.

A third generation physician, Dr. Langer attended the University of Pennsylvania for undergraduate and medical school. He stayed on at Penn and completed his neurosurgical residency under the direction of Eugene S. Flamm, MD. He went on to join Dr. Flamm at a new neurosurgical institute in New York City in 1998. Dr. Langer also completed a mid-career fellowship at SUNY Buffalo in cerebrovascular disease treatment including aneurysms, AVMs and carotid disease.

Dr. Langer worked at the Continuum Health System at Mount Sinai in New York until 2010, when he joined the neurosurgery department at North Shore-LIJ (now Northwell Health). Dr. Langer established the Moyamoya Center of New York and developed a project focused upon the use of social networking technology and video to enhance the patient experience and improve the medical record. This project has grown into the Health System supported Cirrus Health which continues to creatively disrupt the status quo in patient communication and the current electronic medical record.

In 2013 Dr. Langer was recruited as director of neurosurgery at Lenox Hill Hospital. His goal is to further expand this outstanding clinical entity by creating an entirely new environment for patients and their families. He also maintains an active practice in spinal disease and benign brain tumors including acoustic neuromas and meningiomas.

Dr. Langer has been recognized as a Top Doctor and Best Doctor by numerous publications.He is currently a peer-reviewer for the journals Neurosurgery and AANS Neurosurgeon and is on the medical advisory boards of Box Inc. and Cisco Systems. He is also a founding member of the board of the Brain Technology Institute and an active member of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, as well as the cerebrovascular subsection of these organizations.

He has appeared on CNN, FOX, ABC and CBS as well as the Dr. Oz Show.He has also frequently quoted in the New York Times and numerous other print news sources. Most recently, Dr. Langer was featured in the Wall Street Journal article "What Patients Need to Remember After Leaving the Hospital" for his innovative technology to record crucial steps of patient's experience in the hospital.
