Dr. Hui is a pioneer in the field of integrative medicine. He has been practicing across this interdisciplinary area for the past 40 years, dedicating himself to helping individuals with the most difficult chronic medical problems. Decades before becoming mainstream, he studied anti-aging and regenerative medicine tools and approaches long before they were put into today's common clinical practice.
Over the years, he has fuelled his insatiable passion for learning about the most innovative techniques and modalities already in medical practice around the world. Continually expanding his "toolbox" of therapies, his enduring goal is to help patients heal from their chronic illnesses, regain and sustain their health.
As a complement to conventional methods of treatment, he uses functional medicine, hormone therapies, intravenous therapies, and traditional Chinese medicine, including acupuncture.
Dr. Hui completed his medical degree at the University of Toronto.

Dr. Melody Hui is a trusted expert in Longevity Medicine, recognized for her thoughtful and integrative approach to the field. She is dedicated to advancing personalized, evidence informed strategies that promote long-term vitality, helping individuals optimize energy, cognition, hormonal health, and overall wellness.
With more than a decade of experience practicing Emergency Medicine in the Greater Toronto Area, Dr. Hui developed a deep clinical foundation and a nuanced understanding of the many factors that influence long-term health. Over time, she also witnessed the limitations of a system designed mainly to react to disease rather than prevent it, a realization that inspired her to pursue a more proactive model of care. She expanded her practice to include longevity and integrative medicine, disciplines that combine advanced diagnostics, proactive care, and a root cause lens to support optimal health.
She is board certified in longevity medicine through the American Academy of Anti-Aging and Regenerative Medicine. She is also certified by the Menopause Society, and has completed advanced training in hormone optimization, metabolic health, and functional medicine. She earned her medical degree from McMaster University.
Dr. Hui also practices at GraceMed Functional Medicine and Hormonal Health, consults for RegenaLife, a longevity medtech company, and serves as a Longevity Advisor at Felix Health, Canada's leading digital healthcare platform.
