Dr. John Gannage, MD, CCFP
Hi, I’m Dr. John Gannage, founder of Markham Integrative Medicine. My medical background is within the scope of Family Practice, a specialty that ideally emphasizes continuity of care, comprehensive care, health promotion and prevention. Recognizing some limitations in my conventional training, particularly in regard to supporting the “chronically unwell” and today’s chronic disease epidemics, I began the scientific process of searching and observing outside of standard medical training. I support strongly the concept of Integrative Medicine, which incorporates aspects of Complementary Medicine adjunctively with Conventional Medicine. I offer, therefore, a holistic approach with specific emphasis on lifestyle counselling, nutrition and nutritional therapy, functional medicine, and mind-body medicine, areas in which I have special training.
Dr. John Gannage, holding an active medical licence in good standing with the College of Physicians and Surgeons of Ontario (CPSO), and as a longstanding practitioner of CAM, is considered an expert in the CAM field. Dr. Gannage has been regularly requested to offer his opinion regarding current standard of care and best practices within his professional domain.
Dr. Gannage founded and is currently the Medical Director of Markham Integrative Medicine, where he has been emphasizing prevention and treatment of chronic disease through nutrition, detoxification, immune system modulation and reduction of oxidative stress since 1998.
Dr. Gannage has special focus in assisting children and families affected by developmental issues, including autism, using biomedical therapy. Still, the majority of Dr. Gannage’s practice is for chronic illness and conditions among adults, for which he has both learned and developed specific protocols from a functional medicine perspective.
Dr. Gannage has membership in MAPS, the American College for Advancement in Medicine (ACAM), the Canadian Society of Orthomolecular Medicine (CSOM), the Ontario Medical Association (OMA), and its Section on Complementary and Integrative Medicine, and the Canadian Association of Physicians for the Environment (CAPE).
In 2014, “Integrative Medicine for Children’s Mental Health” was launched. This program was researched, written and presented by Dr. Gannage at 3 Canadian Universities across the country. The professional seminar, co-sponsored by Mindful and CSOM, was recognized for accreditation by the College of Family Physicians of Canada (CFPC). Dr. Gannage continued the professional seminars in 2015 and 2016, in Toronto, Vancouver, Calgary and Hamilton. The program’s objective is to provide an evidence-based approach to ASD, ADHD and other mental health conditions in children to health professionals, including medical doctors, with clinical management guidelines and research outlined. Dr. Gannage emphasizes nutrition and environmental factors, and explains the relationship of the gut-microbiome-brain axis, oxidative stress, immune dysregulation and environmental toxicants to mental health disorders. In 2019, the program was modernized and re-launched under the title “Nutritional and Environmental Influences on Neurodevelopment”, after extensive research and content upgrades, and presented to professional audiences in Vancouver and Toronto on the heels of re-accreditation by the CFPC.
Dr. Gannage regularly educates the community and other practitioners through public presentations, has appeared on radio, lectured at ACAM’s biannual medical conference and written numerous articles for publication.
