Professor Harrison Weisinger MSc MBBS PhD is the founder of My Performance Doctor, a membership-based preventative medicine service built on a simple premise — that healthcare should be proactive, personalised, and driven by data, not waiting rooms. Before studying medicine, Dr Harry had already completed his masters and doctorate in nutrition and neuroscience at the University of Melbourne, with a focus on visual neurophysiology and visual development. He holds a Bachelor of Science in Optometry (1992), a Master's in Nutrition (1996), a Doctorate in Visual Neuroscience (1999), and a Bachelor of Medicine, Bachelor of Surgery (2005) — all from the University of Melbourne. He went on to complete fellowships at the Florey Institute of Neuroscience and Mental Health and the National Institutes of Health (NIH) in Washington, D.C., and has published in some of the world's most prestigious journals including Nature Medicine, Science, and PNAS. He has been awarded national competitive grants and fellowships from the NHMRC and ARC. Dr Harry lobbied for and established Australia's fourth optometry program and has held professorial appointments at Australian universities. He served as Global Director of Professional Services at Specsavers, where his mission was to improve the eye health of millions through clinical advancements and technology, working directly with founders Doug and Dame Mary Perkins. Dr Harry's own journey gives him an authority that goes beyond credentials. Diagnosed with Crohn's disease at 18, he endured approximately 40 hospital admissions and two bowel resections. At 35, he was diagnosed with and treated for non-Hodgkin's lymphoma. He underwent a total hip replacement at 39, and at 40, experienced a subtotal occlusion of his right coronary artery. Now 54, Dr Harry has enjoyed 15 years of exceptionally good health — a transformation he credits to the same proactive, data-driven approach that underpins My Performance Doctor. He is also a competitive athlete in his own right, standing on the top step at Masters cycling championships, including winning gold at the 2021 Australian Road National Championships team trials. Over his career, Dr Harry has worked with world tour professional and masters champion cyclists, national champion triathletes, title-holding MMA fighters, Olympians, and AFL Hall of Famers. He founded My Performance Doctor because he believed the healthcare system was failing people who wanted more than reactive, one-size-fits-all medicine — and that it could do better. He co-founded Kurk in 2022 with his close friend and fellow cancer survivor, Trent Scanlen. Born during Trent's third round of chemotherapy, Kurk is a science-backed curcumin nutraceutical using proprietary Micelle technology for optimal absorption. It is used by Special Forces and Olympians and endorsed by Tom Hardy, Lyndon Lea, Andrea Horwood, Bill Moss AO, and Doug and Dame Mary Perkins. Today, My Performance Doctor serves patients across Australia and internationally — from business leaders and elite athletes to anyone who wants more from their healthcare — combining personalised health strategy with data-driven diagnostics to help people add years to life and life to years.
