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 Flamm, MD. Dr. Langer also completed a mid-career fellowship at the University at Buffalo in cerebrovascular disease treatment including aneurysms, AVMs, and carotid disease.
Dr. Langer established the Moyamoya Center of the Neuroscience Institute at Northwell Health and developed a project focused on the use of social networking technology and video to enhance the patient experience and improve the medical record which has become Playback Health- a Snapchat and Instagram for healthcare.
In 2013 Dr. Langer was recruited as director of neurosurgery at Lenox Hill and subsequently went on to help establish the first Department of Neurosurgery at Lenox Hill Hospital. He is currently Chairman of this new department. His goal is to further expand this program by creating an environment emphasizing collaboration, communication and world-class clinical care.
