Denis Marier, ND, MA

Dennis.jpgDr. Marier is known for his ability to connect with patients and navigate health concerns and trauma with compassion and skill.  Throughout his almost twenty years of practice he has come to realize that addressing the root cause of disease includes a deep and thorough look at any psycho-spiritual adverse events of a person’s history, including inter-generational factors, as well as life traumas and stressors.  He helps patients find healing through gentle therapies, education and support, and their connection to nature. 

Dr Denis Marier brings a wealth of international experience through his medical relief work and wilderness therapies to his work with patients. He also has a master’s degree in Ecopsychology, which looks at how our interaction with the natural world informs our physical, mental, emotional, and spiritual health.
