Dr. Michael Vassilyadi, Pediatric Neurosurgeon

After completing neurosurgery residency at the Montreal Neurological Hospital and pediatric neurosurgery fellowship at the Montreal Children’s Hospital, I joined the University of Ottawa’s Faculty of Medicine in 1996 and started working at the Children’s Hospital of Eastern Ontario until my retirement from CHEO in November of 2018. 

I continue to work at the University of Ottawa and TOH where I am an Associate Professor of Surgery and Pediatrics.  I am a strong advocate for head and spine injury prevention; for over two decades I have been presenting at many schools and community organizations about “thinking first” and the importance of protecting one’s brain.  I speak English, French, and Greek.


How to Access

Dr. Vassilyadi sees patients in consultation when referred by their Family physician, Pediatrician or primary care provider.  Referrals can be sent to our clinic by physicians by fax at 613-564-6627.
