Awards & Recognitions

Dr. Rogers Prize Colloquium Vancouver 2013

Dr. Gannage presented the “Mind-Body Continuum from a Nutrition Perspective” at the Dr. Rogers Prize Colloquium Vancouver 2013, attended by health providers and local residents.

The Dr. Rogers Prize is awarded every 2 years to celebrate the achievements of researchers, practitioners, and others in the field of complementary and alternative (CAM) health care. It is the largest prize of its kind in North America.

Dr. John Gannage is a medical doctor practicing in Ontario. His conventional medical training and experience allows him to provide expert trusted health advice. His pioneering work as an integrative medical practitioner gives him the ability to blend conventional medicine with the ever growing consumer interest in natural products, and complementary therapies.


Canadian Society for Orthomolecular Medicine and MINDFUL Co-Sponsor Dr. Gannage’s “Integrative Medicine for Children’s Mental Health”

On June 7, 2014, Dr. John Gannage, MD, CCFP, reviewed the current evidence and present clinical applications of integrative medicine for children’s mental health. More than half of his practice consists of working with developmentally delayed children and their families, recommending therapeutic diet plans, customized nutrient support, management of environmental exposures and support for immune and digestive systems.  His clinical expertise and research findings were on display in a program targeting health practitioners, approved by the College of Family Physicians of Canada for 7.5 CME study credits, as well as accredited for Naturopathic Doctors.

Heading West! – Taking “Integrative Medicine for Children’s Mental Health” on the road!

A success in Toronto in June 2014, Dr. Gannage presents his accredited program to health practitioners, including Family Physicians and Naturopathic Doctors, in Calgary and Vancouver September 27 and 28.  This program is co-sponsored by Mindful and the Canadian Society of Orthomolecular Medicine (CSOM), and has been approved by  the College of Family Physicians of Canada for 7.5 CME study hours.


“GP Focused Practice” Designation

As of April 2015, Dr. Gannage’s application for the Focused Practice designation was approved by the Ministry of Health and the OMA, allowing him to provide consults under OHIP for standard medicine services without the patient’s primary care doctor always being penalized economically. This helps to solve the problem of providing Integrative Medicine services to patients that have a GP who is concerned about the economic impact of rostered patients seeking medical assistance in Dr. Gannage’s practice.

IMPORTANT NOTE:  this does not impact the fees paid for alternative medicine services, which are billed directly to the patient.  The Integrative medicine practice requires integrative billing, where OHIP pays for the basic standard medical component but nothing more.


Mind-alive! Exploring Natural Medicine for Mental Health

2015. GANNAGE WAS THE KEYNOTE SPEAKER for this public event in Vancouver on October 24, 2015.

He presented his lecture Creating Healthy Minds in Children: Nutritional and Environmental Factors.

Video excerpts of the 90 minute presentation are included here.


Integrative Medicine for Children’s Mental Health

Dr. Gannage continues his dedication to changing the paradigm, by focussing on education of physicians and allied health professionals regarding nutrition and environmental factors in mental health, particularly children.  His pioneering work is reaching more health providers with each passing year.

His well-received CME program was again presented in 2015 both in Toronto and Vancouver, with a Calgary date set for January 30, 2016.  The message is clear – there is a gap in care, the need is high, the epidemic of mental health disorders is growing, prevention is critical, and management strategies can and should focus on understanding early brain development from a nutrition and toxin perspective.


Dr. Gannage To Speak At Integrative Medicine For Mental Health Conference

Dr. Gannage will be speaking on October 2nd at the 2016 IMMH conference in Washington, DC, on Environmental Medicine: The Role of Toxins in Children’s Mental Health.

CME @ Sea: Reflections

This summer, Dr. Gannage gave 10 presentations to physicians aboard a cruise ship on the Mediterranean Sea. Over the course of 10 days, he presented his comprehensive program on Integrative Medicine for Children’s Mental Health to a group of conventional physicians. The doctors learned about and saw evidence for the many roles played by diet and nutrition, the gut, environmental factors, oxidative stress, methylation, and mitochondrial dysfunction in children’s mental health conditions, autism, ADD and ADHD, as well as in chronic disease and health as a whole.

Below are scenes and observations from the journey.

What the Cruise experience reminded me of is the extent to which some have a hard time accepting “new truths”. They may do so on their own time.  Or, they may never.

For physicians, many of whom have been indoctrinated into a certain mindset, acceptance depends not only on the strength of the argument or evidence, which the 10 Integrative Medicine presentations provided to a high degree.

It also is based upon whether highly skilled and educated individuals can remove filters and  break free into an open mind (and therefore hear the evidence to begin with), and recognize what their incomplete and perhaps flawed existing viewpoint is costing them, and their patients.   Can they question the paradigm and information that’s been rammed down their throats, or subtly/insidiously repeated, from various sources during the course of a career in medicine?   A few wouldn’t “listen”, simply couldn’t get to the point of listening.  Many were, thankfully.

Much of the informal discussion, let alone lectures – at breakfast, at dinner, on the decks, etc. – afforded an opportunity to provide clarification and non-threatening discussion, and during the discourse maybe pry open a mind further.

I am grateful for the many MDs that privately spoke of the value of, and the unanimous written support for,  what they heard.  They were those that  wanted more info about how their patients can access Integrative Medicine services, and more training for themselves. Mission accomplished! … More work to do.
