Dr. Dave Harrison's Biography


I have been playing the trumpet since I was 13 years old. I played all through high school in the concert band and stage band. During pre-med, medical school, and residency I played in a variety of community bands and orchestras. I am now principal trumpet in the Richmond Orchestra, a 40 piece community orchestra and chorus in Richmond, British Columbia.


Following graduation from medical school in 1983 I completed a 3 year residency in Family Medicine/Emergency Medicine. After one year of working in a medium sized emergency department I embarked on a second residency in order to obtain my specialty certification in Emergency Medicine. I was on staff as an Emergency Physician at Vancouver General Hospital from 1990 to 2009. I have been Medical Director of the VGH Hyperbaric Unit since 2003. My practice now involves Diving/Hyperbaric Medicine and research, and teaching.


Kidpower Vancouver is a registered non profit society in Vancouver, Canada dedicated to teaching people of all ages and abilities how to act wisely, stay safe, and believe in themselves. Kidpower teaches a full spectrum of safety skills, ranging from everyday safety to full force fighting using a certified padded instructor. Kidpower Vancouver is part of a larger organization, Kidpower/Teenpower/Fullpower International.

I am the Center Director and Full Force Instructor for Kidpower Vancouver. I am also a member of the Senior Leadership Council for Kidpower/Teenpower/Fullpower International and a part of the training team for new instructors. My work with Kidpower Vancouver is easily as rewarding as anything I have experienced in 20 years as a physician.
