About Hyperbaric Vermont

Hyperbaric Vermont is a 501c3 nonprofit. Our mission is to make hyperbaric oxygen therapy (HBOT) accessible and affordable for those who can benefit from it. We provide services directly at our treatment facilities in Montpelier and South Burlington, and support other physicians and organizations with a similar vision to do so through our affiliated treatment centers.


Our Board of Directors

Dr. Grace Johnstone

Dr. Grace JohnstoneCertified in Undersea and Hyperbaric Medicine, Dr. Grace Johnstone is the founder and President of Hyperbaric Vermont. Grace practices at Hardwick Chiropractic and teaches chiropractic worldwide for BioGeometric Integration Seminars.

Grace came to hyperbaric medicine through her experience with Lyme Disease which resulted in meningitis and radiculoneuritis. From being completely incapacitated, hyperbaric oxygen therapy brought her back to the chiropractic practice she loves, the active lifestyle she enjoys, and the energy and determination to share this powerful healing modality with others. She is committed to educating people about hyperbaric and to creating the network and facilities that will allow others to get the treatment they need.

Grace graduated from the University of Massachusetts, Amherst, with a degree in Social Thought and Political Economy, received her Doctorate of Chiropractic from Logan University in St. Louis, Missouri, and has continued post-doctoral studies in chiropractic, osteopathy and hyperbaric medicine.  She also has the best of intentions to continue learning to speak Spanish, Norwegian, and to play the bagpipes.

Robin Cornell

Robin CornellRobin Cornell is a whole health practitioner, educator, and life coach with over 35 years and well over 10,000 client hours in clinical and private practice. She is also a creator and facilitator of dozens of experiential workshops and classes that offer practical skills for enhancing health and empowered well-being. Since the beginning of her practice, Robin has worked with a Holistic Healthcare model that presumes every aspect of our being influences – and is in communication with – every other aspect of ourselves; that body, mind, spirit, emotions and environment are all interdependent. This model also presumes there is an innate intelligence available that we can cooperate with to aid in the healing process.
Robin comes to the Hyperbaric Vermont board from this background, and from the gift of receiving hyperbaric treatment two years after what seemed to be a minor slip and head concussion in 2015. This injury turned out to be more traumatic than she would ever have imagined, and she found herself seriously disabled and limited in her ability to function in even the most ordinary daily tasks. Her ability to support herself was severely impacted. Robin’s hyperbaric treatment over nearly six months significantly helped her regain more stamina, clear mindedness, and the capacity to function more competently and consistently in her daily tasks and in her work. Robin is happy to report that over a year later, this improvement has held and gradually improved even after she stopped receiving treatment.
Because Robin has benefited from HBOT treatment, she fully embraces & wishes to support the mission of Hyperbaric Vermont to make HBOT accessible and affordable for those who can benefit from it; by providing education to the public and to physicians as well as outreach to the community and health care organizations about the benefits of hyperbaric oxygen therapy.
