Professional Interests

Dr. Yassari earned his medical degree from the Vienna School of Medicine in Austria and a Master of Science in Experimental Pathology from the University of Chicago. He completed his residency in Neurosurgery at the University of Chicago Medical Center and was a fellow at the MacLean Center for Clinical Medical Ethics. Subsequently he was an instructor at the Johns Hopkins Hospital in Spinal Oncology and Reconstructive and Complex Spine with the Dept. of Neurosurgery. Dr. Yassari specializes in the treatment of complex degenerative, traumatic and neoplastic spine diseases, including intrinsic extradural, intradural and intramedullary spinal cord tumors as well as metastatic spine tumors. Dr. Yassari;s clinical focus is in spinal oncology in collaboration with the Montefiore Einstein Center for Cancer Care and the Department of Radiation Oncology. He combines his training in minimally invasive surgery and spinal oncology with the existing infrastructure for advanced intraoperative image guidance technology at Montefiore Medical Center to offer innovative, cutting-edge surgical treatment options to patients with all aspects of spine pathologies, in particular metastatic spine disease.
