Our Trainers

Mark Giffin is the head personal trainer and owner of the Vault. With 15 years of personal training experience and decades of high-level sport experience, Mark has worked with a diverse range of clients. Each with unique needs and goals, some having never touched a weight and some world champions, Mark applies the same sound concepts that ensure progress while doing so in a safe and attentive manner.

Mark: “Over a 27 year career, I had the honour of representing Canada at the highest levels of international competition. I enjoyed some measure of success. Toward the end of my athletic career I felt strongly motivated to give back to the sport which had given me so much. For two terms I served as president of the Canadian Powerlifting Union and qualified as an International Powerlifting Federation Category 2 Referee. Since retiring from the sport, my greatest satisfaction has been realized in the application of the experience and knowledge earned these past 35 years and be that catalyst for transformative, life changing improvements to the strength and health of my clients.”
