Our Story
Cellregen was founded in 2024 by Daryle Calder, a health industry professional with a 40-year career. He fell ill in 2005 after returning to Australia from an overseas trip. It took doctors 13 years to diagnose him with Chronic Lyme, leaving him with debilitating symptoms.
Seeking a solution, Daryle tried Hyperbaric Oxygen Therapy (HBOT) in Australia, but at $450 per session for 40–60 treatments, it was too costly.

He then traveled to Cyprus, where HBOT was more affordable. After six weeks of intensive treatment, he finally saw the breakthrough he had hoped for. This transformative experience led him to further research HBOT, ultimately becoming the acting CEO of an HBOT clinic in 2020. Learn more about Daryle’s story at www.cellregen.org.
Daryle’s commitment to making Hyperbaric Oxygen Therapy (HBOT) more affordable led to the founding of cellregen.care, a platform providing high-quality, cost-effective mHBOT chambers in Cyprus, Europe and the UK. In partnership with George Kyriacou, a Healthcare Marketing & Patient Experience Strategist, they are working to educate people and promote mHBOT services in Cyprus, the EU, and the UK.
With extensive experience, George specializes in chronic care, longevity, and biohacking treatments. Passionate about integrating medical innovations with personalized care, he helps individuals achieve optimal health and longevity.
