I don't consider Dr. Klevan an actual doctor. The minute he turned away a patient with serious symptoms was the minute he stopped being a doctor for me. He is dismissive, cold and doesn't care for his patients. If I could give him 0 stars, I really would. I would not recommend him to anybody. I went to him in 2017 with extreme bloating, extreme nausea, blood in stool and crepaling stomach pain. He ended up doing colonoscopy and endoscopy. After the procedures he dismissed me by saying that he found nothing and left without any further explanations. Fastforward to 2019 (after living with excruciating pain for 2 years and having numerous trips to the er in which they recommended for me to revisit my original endoscopy doctor, so he could do another endoscopy and compare the results from beofre). Once he saw me again he told me and I quote, "I don't want to do an endoscopy on you. I have done it before and there was nothing." As a doctor he should know that a lot can develop in the human body in a year. He then proceeded to tell me, "I am just a surgeon, I don't actually do the procedures. Just surgeries." Really? Interesting. Then I guess it wasn't you who did my endoscopy and colonoscopy 2 years ago. My symptoms in 2019 were very different from 2017 and much more severe. How he could compare it all as one is beyond me. He refused to treat me and after much back and forth "referred" me to one of his colleagues because he is not the right doctor for my case. Since then I have found a competent doctor who has able to help me and get much better.

Dr.Klevan doesn't do anything but screening, I was told originally that if I needed an operation he would also be the one to perform this - he does not. He turned me away stating he saw no need for surgery or screening based on my symptoms - Excruciating pain, Vomiting after eating, Unable to have bowel movements, A noticeable Lump that prevented me from going, Pain and symptoms that spread through my Entire body leaving me fighting for my life, at one point I was down to just over 100 pounds and now down to tolerating only 2 foods. Just motility issues he said but he can't help me anyways. Waste of Time and he was completely dismissive of what is obviously a Serious Issue.

Dr Ariel Eric Klevan is associated with a scam company called Trissa. When I contacted his office no one was able to help me and directed me back to the scam artists who are not answering their phones or returning my money for a surgery that did not take place. When you take an oath, to do no harm, I thought it would include not taking advantage of patients.

Dr Klevan and staff made me feel comfortable and at ease before - during - and post endoscopy procedure. All staff are personable, compassionate and the clinic is extremely clean & calming! He ordered additional procedures to get to the root cause of my conditions. Thank you!

Dr. Klevan is a very pleasant doctor. He talks with respect, listens and has all the patience to explain procedures multiple times. His pleasant bed side manners and politeness along with knowledge left me with no choice except to change my previous doctor who was considered the top most but for me was zero. I told him Iam not taking certain medicine and he was smiling and said don't worry he would find some other appropriate medicine for me. In my opinion he is an amazing doctor.

Wow, the comments here are amazing and I absolutely agree. My wife as his patient keeps on telling that this Dr is respectful and a mindful listener. My wife's colonoscopy was successful plus her colon was clear. Even after the colonoscopy, Dr Klevan spoke with my wife in a very polite manner. This Dr is HIGHLY recommendable! I wish and pray that ALL doctors in Ontario were like Dr. Klevan. GOD bless you Dr. You are a blessing to humanity!
