Marissa is a Canadian Paralympic athlete and bronze medalist who competes in the 100m and 200m T64 events. Being born without a right foot has never got in the way of Marissa Papaconstantinou pursuing anything she wanted to achieve in life. Originally a soccer and basketball player, Marissa fell in love with sprinting after being fitted for her first running prosthetic (blade) at the age of 12, by the specialists at Holland Bloorview Kids Rehabilitation Hospital whom she now serves as an ambassador for. Marissa joined a local track club in Scarborough, the city she calls home, and was a Canadian record holder a year later.

She is also a proud dog mom to Myles, a cockapoo. Marissa is an experienced and sought after public speaker who inspires audiences with her messages about overcoming adversity and pursuing excellence.
