High Performance Medicine Clinic
At Phenom High Performance Medicine Clinic, we believe your body is designed to feel and perform at its best. Many people accept sub-optimal health as normal, but we’re here to show you that it doesn’t have to be this way. Our Burlington-based clinic helps individuals uncover the root causes of their health issues and guides them on a journey to optimal health and peak performance.

Health. Performance. Potential.
Our Story
Founded by Dr. Callum Cowan, ND, and Dr. Nicola Kempinska, ND, Phenom High Performance Medicine Clinic was created from a shared passion for helping people surpass their health goals. After years of working with elite athletes, including NHL players and Olympic champions, We realized that the same high-performance health strategies used by top performers could benefit everyone—whether athletes, executives, or everyday individuals—enabling them to achieve peak health.
At Phenom HPM, we integrate naturopathic medicine with both functional and conventional medical practices to identify the root causes of health challenges and provide sustainable, long-term solutions. Our personalized approach ensures that each patient receives a tailored plan designed to maximize energy, enhance performance, and improve overall well-being. Today, we are proud to serve clients in Burlington and across Ontario, delivering cutting-edge naturopathic care to those who want to feel and perform better than ever.
Our Mission
At Phenom High Performance Medicine Clinic, our mission is to teach, inspire, and empower people to take their health and performance to new heights. We are committed to helping you become the best version of yourself by addressing the root causes of health issues and providing long-term solutions.
