Cardiologist showed empathy and yet was very professional and to the point. Lacking certain data from my previous provider, he quickly put together a plan that gave me comfort as a new patient going forward. I developed trust and confidence very quickly with his skill.

I have a great deal of respect for Dr Wazni, his skill and reputation but this last visit seemed like he was simply shrugging his shoulders and telling me it is what it Is and didn't seem to offer any hope or opportunity for progress or healing.

Dr. Wazni is my Physician and he is treating me for Afib. He is an amazing physician who is absolutely dedicated to what is best for the patient. I would recommend him without reservation to anyone with heart rhythm problems. I came to Cleveland to have an ablation for my Afib. After my work up and evaluation over several days, he suggested to me that I may benefit from waiting to have the procedure, as a higher dose of my medication was keeping me in control. Most physicians today are volume and revenue focused and it is unusual for a doctor to postpone a scheduled procedure. Dr. Wazni is focused only on doing the right thing. I truly feel I am in great hands with Dr. Wazni.
