"Gary Rhodes is one of the world's foremost health-tech scale-up advisors, driven by an infectious passion for biohacking and longevity. After successfully exiting a multi-million-pound business, he discovered that his beloved grandmother was suffering from osteoporosis — a revelation that ignited his mission to transform how we think about bone health. He has since built a reputation working with leading innovation and wellness brands including Power Plate, Biodensity, GCH Partners, OsteoStrong, and more. Gary brings both entrepreneurial vision and clinical insight to the field of musculoskeletal wellness. At the helm of Screen My Bones®, Gary is rewriting the narrative of skeletal health. His approach utilises Echolight REMS — a cutting-edge, radiation-free technology that measures both bone density and structural quality. This breakthrough enables early, non-invasive screening — not only for older adults, but also for younger populations who have historically been excluded from bone health assessments. Gary's vision is bold yet clear: make bone health accessible, actionable, and preventive — shifting from "fixing fractures" to "fortifying futures." Under his leadership, Screen My Bones offers licensing opportunities to clinics and wellness centres, integrating advanced skeletal screening into routine care."

Under his guidance, these experiences become deeply personal, grounded, and anchored in somatic and spiritual insight. At 'Growing Younger', AJ will invite you to explore the power of silence, darkness, and inner turning — showing how releasing external stimulus can unveil what's truly luminous within.
