functional medicine practitioner,
and environmental toxin expert

Marie is a Functional Medicine practitioner with a particular focus on the role of environmental toxins in chronic disease. Her work centres on detoxification pathways and holistic, systems-based approaches that consider the individual as a whole rather than isolated symptoms.

Her areas of specialist interest include chronic fatigue, autoimmune conditions, gut health, and environmentally driven illness, including mould exposure, Lyme disease, and heavy metal toxicity. Marie’s expertise lies in analysing complex health patterns through a Functional Medicine lens, with an emphasis on root causes, biological systems, and long-term health resilience.
