Dr. Marc Otten earned his medical degree at Cornell University, where he graduated with honors. He completed neurological surgery internship, residency and chief residency at the Columbia University Neurological Institute of New York. In addition, he completed a fellowship at the Minimally Invasive Cranial Base Surgery Center at Thomas Jefferson University in Philadelphia, specializing in endoscopic, micro-surgical and non-operative approaches to brain and spinal disorders.

Dr. Otten's practice is devoted to tumors of the brain and spine, skull base tumors, gliomas, meningiomas, acoustic neuromas, pituitary tumors, craniopharyngiomas, Chiari malformation, and microvascular decompression (MVD) for trigeminal neuralgia, and hemifacial spasm. He also treats degenerative spine disease, intervertebral disc disease, hydrocephalus, and neuro-trauma.

He uses endoscopy, laser ablation, awake craniotomy and other specialized techniques to minimize risk to patients with disorders of the brain and spine. He has published in leading, peer-reviewed journals about his work on non-invasive methods for mapping brain function in patients with brain tumors, which helps maximize tumor resection while maintaining optimum safety.

As a member of the brain tumor center and pituitary team, Dr. Otten is part of a multi-disciplinary group that brings expertise from multiple specialties, including neurosurgery, radiation oncology, neuro-oncology, neuro-endocrinology, ENT and ophthalmology.

Dr. Otten sees patients at NewYork-Presbyterian/Lawrence Hospital in Bronxville, NY and NewYork-Presbyterian/Columbia University Medical Center.
