      The Late Gordon  Ward’s involvement in hyperbarics is multifaceted.
After seeing the amazing results that Hyperbaric
Oxygen had on the recovery and improved quality-of-life for his
brain injured son he knew that he needed to advocate for others.
Despite the overwhelming evidence supporting Hyperbaric Oxygen
for hypoxic brain injury, the ability to receive HBOT treatment was
a constant battle, often at the mercy of doctors who had very limited
knowledge or ability to prescribe same. Gordon was not immune to
the ‘politics’ surrounding Hyperbarics and he made a bold and
conscious choice to give up a lucrative  career to pursue
medical hyperbarics ​and advocate for others.

     Gordon was the Director of Canadian Hyperbarics Ltd. since 1995, during which time he has been responsible for the operation of hyperbaric facilities in Edmonton, Camrose, Red Deer and Calgary.  As a hyperbaric facility, Canadian Hyperbarics has provided training and certification in hyperbarics to many qualified persons including MDs, NDs and Registered Nurses.

In 2011 Registered Nurse Tami Petroski began apprenticing with Gordon Ward. She continued her studies earning a Doctorate of Monastic Medicine and a PhD in Indigineous Medicine and soon opened her Comprehensive Wellness clinic, Apothec Naturals and Wellness Clinic.

     In 2014 Canadian Hyperbarics joined forces with Tami Petroski of Apothec Naturals and Wellness Clinic and together they developed extensive wellness Protocols specializing in Cancer and Lyme Wellness. Since the sudden passing of Gordon Ward, Tami Petroski has carried on the work of Canadian hyperbarics.

     Their concern about the welfare of their patients and their ability to have access to this very valuable and underutilized medical treatment is truly all consuming. Both Tami and Gordon are consummate researchers. Gordon has authored documents on the therapeutic and technical aspects of hyperbaric chambers, practices and applications.

​     Working with chamber manufacturer Barotech Inc, Gordon successfully applied to Health Canada for a Medical Device Licence. His application and presented research was received and subsequently approved and licensed by the Federal Government of Canada, through Health Canada, Therapeutic Products Directorate, Medical Devises Bureau under the Medical Device Licence Number 60118.
