I have had a horrible experience with Dr Armstrong. I had a GI disease that required further investigation, including a colonoscopy and bloodwork. After our first phone consultation, he told me he would send me a requisition for bloodwork immediately after - this was never sent to me. I called his office numerous times requesting the bloodwork requisition, but they said Dr Armstrong hadn't left anything for me, and simply said that they were not able to help me, nor did they put me in touch with Dr Armstrong to provide this. They told me I would have to wait for our 6 month follow up to ask again... After months of struggling to get in touch and figure this out with them, I had to ask another doctor from another office to request the bloodwork. In addition, Dr Armstrong said he would arrange a colonoscopy within a few weeks. This was not arranged by the time of our follow up 6 months later. At the follow up, he apologized for the delay and stated that things were "crazy" in his office, and that he'd arrange the scope over the next few weeks. Another 6 months passed and nothing was booked. At our next FU again, he apologized and said he'd arrange one semi-urgently within the next few weeks. It has been 2.5 years since our initial consultation, and 1.5 years since that last phone appointment, we have met 3 times, and Dr Armstrong has never provided me with any of the bloodwork requisitions or appointments for colonoscopies that he promised at each visit... nor any further follow up for that matter.

I ended up asking for a referral from my GP to another GI doctor in Hamilton, who amazingly arranged the scope within 2 weeks after the initial consultation.

I would best describe my experience with Dr Armstrong as one of gross negligence from a physician and their office. I would consider this level of patient care as reaching criteria to be reported to the college, with an obvious need for intervention and significant improvement, except for the fact that I understand how unpleasant that experience is for a physician. That said, this is unacceptable and negligent practice from a physician. I hope that Dr Armstrong reads this and re-evaluates the way in which he manages patients, as this is certainly the worst experience I've ever had with a physician.

Dr Armstrong is the best doctor I have had the privilege of knowing. He has solve rare issues other doctors missed. He has a scientific mind, open, sometimes the clinic is busy and you must wait.
But that’s because he gives his patients the proper time and care. Cheers thks again for the figuring things out! Cheers S

Dr. Armstrong saw me for the first time. He was on time, thorough, caring, knowledgeable, answered all my questions and explained everything “the old fashioned way”. He is a great asset to McMaster Hospital

Dr. Armstrong is the best GI doc that I have seen. Yes, I do have to wait, but when I am seeing him he never makes me feel rushed. If I get that treatment I would expect that everyone would get that treatment. He is a great doctor with a great bedside manner. He has a good sense of humour and truly cares about his patients. He is the type of doctor that I wish all of my doctors were!

Dr Armstrong is an amazing doctor!! I have seen him for the last seven or so years and he always takes the time to listen and address my issues. Having said that you may have to wait an hour or so as he treats all his patients this way! So I guess if your health issue isn’t worth an hour or so you may like to go to other Dr for a drive thur.
That said he solved an issue that no else figured out and is truly top notch!!

I have been seeing Dr Armstrong for over a year. I know the wait is slow but believe me well worth it. I have been hospitalized and so very ill and no one but Dr Armstrobg would listen to me. He is old school and truly cares as much as he can. Although I would love to be all figured out and fixed I understand others are sick as well and suffering takes it toll physically and mentally. After a year and 2 months of not being able to eat solid foods and airway cutting off Dr. Armstrong more than any other doctor is starting to see some diagnosis as to what's going on when others gave up he did not. Still I need more tests and a surgeon but I'm hoping soon I will start a road to recovery. I'm waiting now for surgeon and more tests but at least finally I'm getting some answers. I know it rough especially waiting it's torture and scary but hospitals emerge don't seem to have knowledge on Gastro and if any doctor will stand by you and not give up its Doctor Armstrong. He spends quality time with you as much as other patients. It's our health care today that makes the long waits and because he's so knowledgable and experienced he takes his time and so many gi to him for help. When no one else has found a diagnosis I have recently found out I have a 10 cm hiatus hernia that slides as well not easily to detect. I also have gallbladder only working at 50 % function and I'm waiting more tests for phrenic nerve damage and few more different Gastro test before I see a surgeon in 3 weeks. If your suffering and no answers I highly recommend Dr Anstrong.
