I have been a patient of Dr Quinn for over 25 years. He was part of an elite team that saved my life in 2001 and gave me almost 20 more years with a woman l was proud to call my wife prior to her passing in 2021. Thank you, Brendan Patrick Quinn. You were much more than a doctor, you were a friend. I wish you the very best in your retirement. I will miss my visits with you; they were so much more than mere appointements. .

Pick out all the bad reviews on this doctor and my review is same. He is terrible. Shouldn't be practicing anymore. Something just not right.

I was referred to Dr. Quinn after going to the Emergence at the Montfort Hospital in mid-2023. He was informative and respectful when I saw him in his office at the Montfort. He scheduled various tests of my heart and gave me the results in the Fall 2023. He wanted to do more tests so that he could find out the maximum amount of information on my heart. After these were done I met with him in his office to go over the results. His manner, knowledge, and concern were outstanding. I admire this cardiologist and am grateful for his comprehensive and thorough work-up of my heart condition!

Dr. Quinn has been most helpful with my heart problems. He is calm and informative, always able to explain what is happening and providing solutions.

Horrible manners. Regardless of how unhappy he may be with his patients or their families, this man has no right to raise his voice at them. Instead of checking for understanding, he berated us, raised his voice and made us feel like absolute nothing. If only he knew the whole story he’d probably change his tone. I’ve rated 1* for all because of his unprofessionalism and manners.

Brendan is an excellent Doctor who has always been patient and informative of any question or concern that I have.

Dr. Quinn has been especially helpful to me. He is courteous and informative.

Dr. Quinn is a brilliant and knowledgeable doctor and on top of that is also a very caring person.

Dr. Quinn is very knowledgable and a caring person including his staff are very cooperative. Thank you so much for all of you.

Read the other reviews + same pattern emerges...he is arrogant," god like complex"...agree with last comment in saying if ur stressed out before u see ur cardilogist then it's time to find another...he made me cry in an appointment, totally disregarded my worries..he actually said what r u worried about, "they r people with more severe problems than u" ..so wanted to change, then had episodes at emergency, then went back c him, c if his attitude changed, nope!! He actually said I could go, without even looking at the report/results...I called him on it, then he continuously berated the doctors report saying they don't know what they're talking about" again only his option mattered. .so now have fantastic cardilogist from Heart Institute...so run, find another doctor folks!! The staff is beyond awesome ( Kelly + technicians!!!)
