Current Role Working With The Athletic Population

I mostly work with masters athletes in Tennis, Squash, Golf, and other sports who have spine, hip, knee, and shoulder pain.  I also work with competitive athletes, on a case-by-case basis, who are mostly involved in marathon, cycling, and competitive tennis.  

Previously I was the Conditioning Coach/Consultant, University of Toronto Women's Volleyball 2004-2011, where I continued to work with many athletes during their summer beach seasons.  This led to over half a dozen National #1 teams in all age groups and producing over half a dozen FIVB World Tour Canadian athletes.  Two of these athletes (Kristina Valjas and Heather Bansley) represented Canada at the 2016 Summer Olympics.

As a consultant to the Toronto Lawn Tennis Club, I worked with junior tennis and squash players to help them progress to the national team, overcome their injuries to secure university athletics scholarships.  I have also previously worked with elite junior alpine skiers (ages 15-17) in their recovery after surgery (intramedullary pin for tibial fracture) to return them to competition.

Professional Philosophy
  • Always be aware of your personal biases, whether it is regarding outcomes (confirmation bias) or attitudes towards different approaches to therapy or training.
  • The good thing about science is that it still works even if you don't believe in it.
  • Keep learning even if you think you are an expert in the field.  There is always someone who will know more than you, and who can help you get even better, so you can better help others.
