Dr. Mark Donohoe, ACNEM President, graduated from Sydney University in 1980, opening his medical practice on the Central Coast New South Wales in 1983. The patients of his new practice led him into the fields of Environmental Medicine and Nutritional Medicine. He was awarded fellowships from the Australian Society of Environmental Medicine (ASEM), the Australasian College of Nutritional & Environmental Medicine (ACNEM), and more recently the Australasian Society of Lifestyle Medicine (ASLM). Over his 38 years in practice, Mark has specialised in the fields of chronic fatigue syndrome, environmental and occupational toxicology, and sensory sensitivities including multiple chemical sensitivity. Mark works with his wife, Fiona, at Mosman Integrative Medicine in Sydney. While he focuses on causes of illnesses and diseases, Fiona manages the healthcare side of the practice where she and other natural healthcare practitioners provide consultations and classes in yoga, Qi gong, pregnancy yoga, meditation, mindfulness and movement. Mark and Fiona work together with an underlying philosophy that health in all its forms is the best prevention of disease, and that most disease is best managed by clean air, clean food, clean water and a commitment to a diet and lifestyle that is health enhancing.
