Dr. Gannage has made a significant and meaningful improvement in the life of my son and in that of my family. He cares about his patients and is at the apex of his field. I am very glad that he is our doctor. Thank you, Dr. Gannage.

My experience with Dr. Gannage was unpleasant as he was short tempered, defensive, and very rude. If you don't like your job perhaps you should consider a different profession. Moreover, people who are secure in themselves are not quick to anger.

While Dr G is knowledgeable, He lacks empathy for his patients, and you can see that show in his demeanour. He has poor manners, and comes off as Rude. He also carries himself with a huge ego, it’s appalling and personally I would never give my money to a person with such bad character. If anyone else has had to experience his misconduct you should reach out file a report with CPSO.

Dr. John Gannage's response
We’re sorry to hear that you had this experience. While we won’t get into details here in order to respect privacy and confidentiality, we can honestly say that self-reflection is an important part of our process.

However, speaking for Dr. Gannage and all of our staff, our immense interest in helping people and our patients is the entire reason we’re here. The stories and gratitude expressed in our many five star reviews should help demonstrate this. We feel Dr. Gannage’s long career and body of work speak for themselves, undeterred by obstacles and threats.

I find the reviews helpful so I tray and offer feedback where I can for other patients. I am a new patient of Dr. Gannage. (seeing him for a few months). I reached out to him because the regular medical system saved my life, but then chewed me up and spit me out. I was living with daily s allergic reactions to everything I eat, plus a bunch of other stuff. Dr. Gannage performed some specialized tests and figured out what is happening to my gut health, as well as my Histamine intolerance. No the tests are not covered by ohip, and as a functional specialist MD his fees are not covered but if you are chronically ill you find a way. I am feeling hopeful I can actually enjoy food again and not be scared of experiencing intense allergic reactions everytime I eat. I am already starting to feel a bit better through the diet suggestions and a few supplements. If you need a hand holder I suggest you bring a support person to your appointment. I feel Dr. Gannage takes a no nonsense approach in talking to you, which some patients may interpret as not the best bedside manner.

I wanted to take time to write a review for Dr. Gannage.
I came to Dr. gannage very ill after a severe autoimmune reaction. The traditional medical system had failed me and I was depressed and hopeless. I explained my issues to Dr. Gannage, he was nonjudgmental and didn’t make me feel like my symptoms were all in my head like previous practitioners. He was correct in his initial diagnosis of my autoimmune issue. I followed the supplements, diet changes and lifestyle modification recommendations he made closely.
I can honestly say that, despite my autoimmune conditions, I am living a very full and happy life now. I am in graduate school, working full-time, and able to care fully for my children. Although I know I will always have medical issues, I have much more hopeful outlook for my future. Dr Gannage is a brilliant man and I respect him immensely.
I don’t know where I would be without his help during my darkest times. It anyone is on the fence about accessing his services, I can honestly say it was one of the best decisions of my life. Thank you Dr. Gannage.

My family have been long time patients of Dr. G. To say he has saved our lives would be an understatement. If you are out of options with the system, please make an appointment with Dr. G

None of the ratings allow you to rank his approach, which is quite rude, abrupt and he generally has a poor bedside manner. I was quite shocked by his approach, he interacts as if the world is out to get him (and his ego). While he is knowledgeable, he doesn't seem truly interested in helping. Maybe years of experience has made him jaded and condescending. Altogether, I don't think he is specialized in anything different than any another ND.

Dr. John Gannage's response
Dr Gannage’s goal is for a positive experience for the patients he consults with, sometimes more challenging in these times by phone especially. He appreciates all feedback, with a preference that any concerns about himself, his practice or his staff be communicated to him directly, for discussion and learning. As for his hard-earned and distinguishing credentials, our feeling is that they very much speak for themselves. All the best to you and your family.
