Patient Reviews
Oct 17, 2022
Dr O'Neill is the best of the best. I am very lucky to have him as my Cardiologist. He took the time, never rushed us. After my procedure, he came to see me everyday while I was in the hospital, made sure that I am okay and explained what I was going through everyday. I felt safe and cared for under his supervision. During my procedure, he was very kind to explain everything in detail not only to us (my wife and I) but also my Brother-in-law who was a EP Physician (Cardiologist). He made us feel very safe and confident in what we were getting into. I owe my life to his expertise and care.
