David Leaf Tribute page

There are people who change the course of your life in just a few seconds. David Leaf was one of those people for me. From my very first seminar in Applied Kinesiology, I saw his genius for analyzing human biomechanics and connecting it to all aspects of health. I had been promised a holistic chiropractic approach when I first arrived at university… David gave me the tools to truly address the whole person.

After my first class with David in 2000, I told myself that one day I would teach AK! And I had always dreaded public speaking!! From that first course onward, I read, studied, analyzed, and always kept in mind the famous question… Why? David, like his spiritual father George Goodheart, always had that question in mind when treating a patient. It’s now been 25 years that I’ve been asking myself “why?”

Thank you, David, for being my first mentor in my AK journey, thank you for allowing me to co-teach some modules with you (some of the greatest challenges of my life!). Thank you for trusting me to carry forward the development of AK in Quebec after I earned my DIBAK. Thank you for challenging me and questioning me on so many topics! It was a privilege to learn from such a genius. It was a privilege to pay tribute to him on several occasions for his dedication to AK in Quebec and around the world.

Thanks to David, I have a job that isn’t a job, but a passion. Thanks to David, I’ve been teaching Applied Kinesiology since 2006. AK has just lost its very first true DIBAK, who passed the exams in 1975. We’ve just lost a genius—someone who was able to structure George Goodheart’s ideas while also developing many new concepts.

I feel privileged to have learned from this master. I had the chance to hug him one last time in Dallas last summer, during his final appearance on stage. I had the chance to tell him, “Thank you for everything.”
REST IN PEACE David Leaf, I hope you had the time of your life. 🙏
