Lets get the Bio from the source himself: 


I have an interesting educational combination of physiotherapy, chiropractic and strength and conditioning training.   I have spent 2 1/2 years completing a MSc in spine biomechanics, 4 full time years in chiropractic college (spending more than 15 hours per week for four years practicing manual therapy) and seven years working as a researcher in exercise and clinical biomechanics.  After working for several years I spent an additional 2 years obtaining a MSc in Physiotherapy (Queen's)

Awards and Academic Pursuits

I have been in the rehabilitation field for more than 20 years. Following my undergraduate degree in Kinesiology (4 full time University years)  I was awarded the Canadian Society for ExercisePhysiology Gold Medal for highest academic performance in Kinesiology.  This degree allowed me to obtain certification as a Strength and ConditioningSpecialist and Certified Fitness Appraiser and I have worked as a Strength and Conditioning coach for Sir Wilfrid University's Men's Basketball team and for Queen's University Women's Varsity Hockey Team.

My success in university resulted in being awarded a graduate scholarship (NSERC) toWaterloo University to be 1 of only 2 Masters students studying with Dr Stu McGill, a world leader in Spine Biomechanics, exercise prescription and athletic performance.

As a faculty member at the Canadian MemorialChiropractic College I developed a research program that producedmore than 20 publications on exercise biomechanics, golf fitness andthe science of manual therapy. I taught more than 25 graduate students in Spine Biomechanics and Research Instrumentation and supervised more than 50 students and 20 undegraduate research theses.

I was subsequently awarded a  Researcher of the Year award by the Ontario Chiropractic Association.
