Spencer Delisle

Mental Performance Coach

Spencer Delisle is a mental performance coach who for the past ten years has been teaching empirically validated breathing, yoga, and meditation techniques for hundreds of people across North America, Europe, and Asia. He has also worked with various athletes from different sports, members of the European Parliament, Army, Marines, Special Forces from the US Military, top business executives from organisations such as IBM, SAP, and the Government of Canada, as well as institutions such as McGill, Western, University of Toronto, and La Sorbonne. Spencer was awarded a bachelor of science from Mount Allison University, graduating the president of his class. Formerly involved in academic research at Mount Allison, and McGill University in the fields of oncology and, cardiology respectively, he has also worked on the corporate side of science in marketing with Novartis Pharmaceuticals. 

As a youth learning the game of tennis at Queen’s Quay Tennis Club in Toronto in the late eighties, Spencer fell in love with tennis from a young age. Tennis was a place to compete, a channel for his disciplined spirit, a time to take a break from the stresses of life and enter a place where for those few hours nothing else existed except the freedom of giving your 100% in the moment. Spencer then transitioned to focus on track and field, and basketball. In track and field Spencer was ranked in the top 5 in the 800 meter division in Metro Toronto and in basketball competed for North Toronto Collegiate Institute facing hard nosed teams like Eastern Commerce Collegiate Institute and their star Jamal Magloire, who would later go on to play in the NBA. After focusing his university extracurricular time in his first three years in the scientific laboratory, in his final year Spencer played a short stint on the 1999/2000 ACAA Mount Allison Mounties but left the team after breaking his wrist in the preseason. 

In 2015 Spencer was the master of ceremonies inaugurating the first UN International Day of Yoga at the prestigious Lincoln Center in New York City where international ministers, elite athletes, senior UN representatives and heads of industry came together to recognize the benefits of Yoga. In 2017 Spencer was one of the master of ceremonies for the World Culture Festival, close to 4 million people from over 155 countries gathered together in New Delhi India demonstrating the power of unity and peace, celebrating the benefits of yoga, breathing techniques and meditation in sport, business, politics, and with the general public.

Spencer is currently involved on behalf of the Art of Living Foundation, in scientific research studying the effects of breathing, yoga and meditation techniques on anxiety, depression, impulsivity, and post traumatic stress. The research is in partnership with the London Health Science Center and The Schulich School of Medicine at the University of Western Ontario.
