Biography

    Johanna T. Fifi, MD, is a board-certified neuroendovascular surgeon, Assistant Professor of Neurology, Neurosurgery, and Radiology, and Director of the Endovascular Stroke Program in the Mount Sinai Health System. She specializes in the endovascular treatment of cerebrovascular disorders including stroke, intracranial and carotid stenosis, brain aneurysms, arteriovenous malformations and fistulas of the brain and spine, pre-operative embolization of tumors, as well as craniofacial vascular lesions in adults and children. She sees patients at The Mount Sinai Hospital in Klingenstein Clinical Center, at 1450 Madison Avenue. Dr. Fifi was born in Trinidad, British West Indies, where many of her family still resides. She attended high school in Florida and was subsequently awarded a full four year academic scholarship as a Trustee Scholar at Boston University. During college, she was accepted into a combined program to complete studies in biomedical engineering and then medicine at Boston University School of Medicine. In 2000, she moved to Philadelphia to perform her medicine internship and neurology residency at Thomas Jefferson University Hospital. From 2004 to 2006, Dr. Fifi was a clinical fellow in stroke and cerebrovascular disorders at the National Institutes of Health (NIH) in Bethesda, Maryland. While at the NIH, she was co-investigator of several phase II and phase III clinical trials for treatment of acute ischemic stroke. Dr. Fifi then trained in Interventional Neuro-Radiology under the tutelage of William Bank, MD and at Columbia University. After her neurointerventional training, Dr. Fifi was accepted at the Hyman-Newman Institute of Neurology and Neurosurgery (INN) at Mount Sinai St. Luke's, Mount Sinai Roosevelt Hospital, and Mount Sinai Beth Israel for further studies of pediatric neurointerventions under the tutelage of Alejandro Berenstein, MD. During this period, she was invited to join the INN as a staff physician where she developed a clinical practice taking care of patients with stroke and other cerebrovascular disorders. Dr. Fifi continues with clinical research as investigator in several multi-center trials. Dr. Fifi published her research in peer reviewed journals and presented her work at national and international meetings, including the International Stroke Conference. She is a member of the American Stroke Association, Society for Vascular and Interventional Neurology, and Society of NeuroInterventional Surgery. Dr. Fifi specializes in the endovascular treatment of cerebrovascular disorders including acute stroke, carotid stenosis, brain aneurysms, arteriovenous malformations, as well as craniofacial vascular lesions in both adults and children.
