Our Board of Directors

Dr. Grace Johnstone – Founder, President, and Medical Director

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

Grace came to hyperbaric medicine through her experience contracting Lyme Disease, which resulted in severe meningitis and radiculoneuritis.

Grace was completely incapacitated for a year, until intensive 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 Oxygen Therapy, and to creating a network of treatment facilities to care for anyone need of this powerful modality.

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.

Hannah dedicated over 20 years to Heartbeet and during her tenure there joined national and statewide conversations and action to expand meaningful options for adult life, removing barriers and increasing opportunities for adults with developmental disabilities.

Hannah pursued a Masters in Special Education at Antioch New England, graduating in 2016. In 2020, Hannah felt called to leave Heartbeet Lifesharing, and in an effort to deepen and expand her understanding of diversity, equity, justice and inclusion, through a social work and policy lens, she attended the University of Vermont’s Masters of Social Work program.

Our Patient Care Team

Jeri Belisle, Patient Care – South Burlington

Jeri studied molecular biology and cognitive neuroscience at Princeton University and University College London, only to discover that the questions she’s most interested in can’t be answered in a laboratory. For the past 20 years she has alternately worked as a freelance scientific editor, massage therapist, homeschool mom, and homecare LNA. She has also dug in the dirt at a few farms and retreat centers, and considers herself a hobby herbalist and wild edible stalker. Her favorite thing about HBOT is that it stimulates and amplifies the body’s innate healing capacities — powerful but not too fancy. Jeri feels honored to support so many wise and dedicated people in their healing process, and to be part of a life-giving nonprofit right in her neighborhood.

Zoie Weisendanger, Patient Care – South Burlington

Originally from Minnesota, Zoie moved to Vermont 3 years ago to pursue her studies in Psychology and English at the University of Vermont. Her interests have always consisted of health care where she has worked locally in Vermont as a Home Health Aid and a Mental Health Worker. Zoie is passionate about her studies, and is working towards becoming a licensed therapist and a psychopharmacology researcher. She loves Hyperbaric Vermont for its welcoming community and its willingness to provide the care patients deserve. The benefits HBOT gifts to patients continues to amaze her, and she is honored to be a part of something so special. While not in class or at HyperBaric Vermont, Zoie can be found deep in the woods hiking or soaking up rays near Lake Champlain.
