Our Hyperbaric Oxygen Therapy Story…

 In early 2021, our mother suffered a Traumatic Brain Injury (TBI) from a fall. The initial CT Scans of her brain and skull did not reveal any damage so medical treatment focused on her cuts and bruises. Weeks later, she developed a brain bleed resulting in neurological symptoms such as headache, loss of strength, balance and peripheral vision.

To see our active mother resigning to the couch because she could barely walk a few steps with a walker was heartbreaking. As the primary caretaker for our two young children, she was always a burst of energy with the smile to match. It was our mission to help her get better.

Traditional western medicine focused on decreasing the inflammation with strong steroids and pain management with opioids. We understand that there is a time and place for this type of intervention, but our mother had showed very little improvement after weeks of this regimen. She was making small gains with physical therapy and chiropractic care, but we just felt stuck.

Thankfully, with the guidance of Dr. Giancarlo Licata from Vital Head & Spine and Dr. Mark Cheng, a world renown Acupuncturist and Strength Coach… we explored the world of Hyperbaric Medicine and NATURAL HEALING WITH OXYGEN!

After one week of treatments, our mother’s constant 7/10 headache pain had decreased to a 3/10. After 4 weeks, her headache was completely gone and found a new sense of energy, strength, mental clarity and CONFIDENCE! We finally found a natural solution that could JUMPSTART her body into healing itself from the inside out.

When she was showing very little progress, we felt hopeless. Now, we are excited see to her up and about as she plays with our kids again.

Needless to say, we were impressed with her results and started to research all of the benefits of simply increasing oxygen in your body. Yes, we knew there were some big time athletes using it for recovery, but had never explored the physiological processes behind it.

Since we need oxygen to live, it only makes sense that things heal much better when you have more of it!

This is why we ultimately felt that this would be an AMAZING THERAPY to share with our clients.
