Assistant Professor of Neurological Surgery

Peleg M. Horowitz, MD, PhD, is a neurosurgeon with expertise in brain tumors and skull base tumors. He provides multidisciplinary care as a member of the neuro-oncology and skull base tumor teams. Dr. Horowitz uses endoscopic and open surgical approaches to the skull base, including advanced stereotactic and 3-D surgical planning for operative treatment and radiosurgery of both benign and malignant brain tumors. In addition to his specialization in neurosurgical oncology, he also provides general neurosurgical care, treating patients with a wide range of conditions, including hydrocephalus, head trauma, and spine pathology in adults and children.

Dr. Horowitz conducts clinical and basic science research, with emphasis on the genetics of brain and skull base tumors. His scholarly work has focused on the pathogenesis and management of nervous system tumors and on the genetic characterization of tumors, controversies in current management and decision-making, surgical technique and complication avoidance. His research on tumor genetics has been published in Nature Genetics and Proceedings of the National Academy of Sciences, and identified several novel genes that drive the formation of meningiomas and pediatric gliomas. His research has been funded by the Brain Science Foundation and the Department of Defense Neurofibromatosis Research Program.

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
