I'm not the most trusting of patients, having experienced doctor malfunctions in the past. So before my initial appointment with Dr. Day I read his book, The Afib Cure. The depth of his knowledge and his ability to explain in a friendly and accessible way were reassuring, and he was the same in person. I had intended just to gather information, but after talking with Dr. Day I realized that I really needed an ablation, and I signed up on the spot. The heart center staff were friendly, efficient, and experienced at dealing with insurance approval. All I had to do was not chicken out, although they told me that I could, which helped a lot because I felt no pressure. On the day of the ablation everything went as planned. My discharge instructions were clear and precise, with contact information for heart center nurses if I had questions. I do not live close to Dr. Day's location and so his staff arranged my one month follow up by telemedicine, which I very much appreciated. Six weeks after ablation, I am feeling great and glad I did this. I feel very lucky to have found such a skilled, committed, and personable electrophysiologist.

Dr. Day is single handedly the best doctor I've ever worked with. He figure out underlying issues with my heart and gave me answers that no other doctor could. He's kind, takes the time you need with him, and is active in staying up to date in latest research and changes in the field. I would send my own family to him and feel completely confident.

The last 3-4 annual checkups have been uneventful (that's the way we like 'em). This time my EKG clocked in at 43 beats per minute. That's slow. And, I really haven't felt very good in the past 6-8 months. Day's assistant suggested a pacemaker and Day confirmed it. So they got me scheduled for Sept 15, if we can work out the insurance details. I appreciate Day's care and attention to details. They've given me hope, my quality of life will improve as a result of it.

Dr. Day was terrific!! His surgical skills are obvious , but his attitude and bed side manner were exceptional. He gave me his full attention. I felt like he would have stayed with me for another hour to answer my questions if I would have needed. It was very obvious that he really cares about his patients!!

I was referred to Dr. Day by my cardiologist for some work that has to be done. Dr. day and his staff welcomed me to their practice and had every thing organized for the future medical procedure. I was very happy that I was referred here. In the past going to new doctors was stressful for me, but Dr. Day was very helpful by explaining what had to be done. His detailed explanation and his willingness to answer my questions put me at ease.
