Leo da Costa, MD

Dr. da Costa received his MD from the Federal University of Minas Gerais, Brazil, in 1995 and finished his neurosurgical training in 2000, also in Brazil. He completed four years of fellowship training at the University of Toronto from 2004 to 2008, including 3 years of Cerebrovascular Surgery and Interventional Neuroradiology. He joined the Division of Neurosurgery as an Assistant Professor in September 2008 and currently works at Sunnybrook Health Sciences Centre, where he holds positions in the Division of Neurosurgery and the Department of Medical Imaging. His major interests are carotid disease and stroke prevention interventions and regulation of cerebral blood flow/vasospasm after injury/subarachnoid hemorrhage. Dr. da Costa is married to Christianne Werneck, a vascular surgeon and Assistant Professor in the University of Toronto Department of Surgery at Trillium Hospital. They have a son, Bernardo, who is 2 1/2 years old.
