Dr. John Cogan came to my rescue at Queen's Emergency in the middle of the night. He quickly and painlessly inserted 2 stents and saved my life. I highly recommend this cardiologist. Dr. Cogan is the best!

Patient
He did my angioplasty, didn't feel any pain. Soon it was over. It was as if his hands were guided by God himself. Mahalo Dr J Cogan. In addition, he talked to another interventional cardiologist about my case Dr Ramy Badawi who called me the next day, already reviewed my record & later scheduled me for consultation. Both doctors in my opinion are not only super competent, but more important patient-compassionate.
