Hello, I’m Dr Gary Dennis, the founder of Cocoon.
I was introduced to mHBOT therapy after suffering a serious brain injury in 2019. Within a matter of weeks the benefits were apparent, but the travel and significant treatment costs soon became a burden. My research told me that treatment with mHBOT should be carried out every day of the week, without breaks, to ensure the best results.
As such, it made sense to have my own chamber at home and took all of the stress out of my recovery. It enabled me to easily stick to a daily regime that not only improved my results, but also saved me money and time.
Our youngest patient to date was two and a half years old. Our eldest in their eighties.
If you have any questions just reach out. I will be happy to discuss your case and help put together a mHBOT treatment programme that best serves your needs.
Installation and training in your own home is very straightforward and we are only a phone call away should you need any follow up help.
Yours in Health,
Gary

Dr Lorene Dennis brings a rare blend of professional expertise and deeply personal experience to her work at Cocoon. With a two-year Diplomate in Neuro-developmental Paediatrics from Melbourne, she is one of only a handful of practitioners in New Zealand with this specialisation.
For years, Lorene ran Connected Families Chiropractic, a practice specialising in children, where she combined advanced chiropractic techniques with a holistic approach to health and family wellbeing. Now working alongside her husband, Dr Gary Dennis, she is fully dedicated to Cocoon’s mission of helping Kiwis recover and thrive through at-home mild Hyperbaric Oxygen Therapy (mHBOT).
Her passion for helping others is inspired by life as a mother of three, including a daughter with Down Syndrome, and further shaped by her husband’s brain injury in 2018. These personal experiences give Lorene a deep understanding of both paediatric care and brain injury rehabilitation - blending clinical expertise with genuine compassion.
At Cocoon, Lorene’s work is driven by a simple belief: every person deserves access to safe, effective, and personalised therapy that supports the body’s natural ability to heal.
