Dr. Rohan Bissoondath, born and raised in Calgary, Alberta, is an innovative physician deeply immersed in the science of health, aging, and precision medicine. He proudly serves as the Founder and Medical Director of XONE Precision Medicine, a clinic focused on advancing proactive, personalized healthcare through the principles of precision medicine.

His academic journey began at the University of Calgary and the University of British Columbia in Vancouver, where he earned a BSc in Zoology in 1989. In pursuit of his passion for medicine, he travelled to Trinidad and Tobago to study at the University of the West Indies, earning his medical degree in 1996. After spending a decade away, he returned home to Calgary in 2001, where he served in various medical roles before founding Preventous Collaborative Health in 2007 with an emphasis on preventive care.

Over time, Dr. Bissoondath became increasingly focused on precision medicine and its potential to make healthcare more proactive, personalized, and informed by a deeper understanding of each individual. His approach to precision medicine is captured in a simple equation: Genome, an individual’s unique genetic makeup, plus Envirome, the environment and lifestyle factors that shape health, equals Phynome. The “Phynome” represents the observable characteristics and health outcomes that emerge from the interaction between genetics and environment.

Dr. Bissoondath’s understanding and practice of precision medicine have been shaped by a wealth of life experiences and professional development, augmented by a diverse range of resources including textbooks, scientific literature, continuing education, and emerging research.

In 2022, his commitment to precision medicine was further strengthened when he earned a postgraduate Certification in Precision Medicine from the University of Calgary’s Department of Medicine. Through XONE Precision Medicine, his goal is to use this approach to help individuals better understand their health, identify meaningful risks and opportunities earlier, and develop personalized strategies designed to support both healthspan and longevity.

Outside his professional commitments, Dr. Bissoondath finds fulfillment in his roles as a father to three daughters and a husband. He promotes a balanced lifestyle encompassing healthy eating, regular physical activity, optimal sleep, and mindfulness.

With XONE Precision Medicine, Dr. Bissoondath brings his vision for proactive, individualized healthcare to Calgary, combining advanced diagnostics, data-driven insights, and clinical interpretation to help people make more informed decisions about their long-term health.
