    The electrophysiologist, Dr Mazzini, was well prepared. He had gone through the written material that was supplied by my regular cardiologist, I felt, regarding office visits, tests and results.He then ordered a test to be done to make sure a pacemaker was going to be the very best treatment for me. I felt at ease during my visit with him and thought he did the best with everything available to him and me in regard to preparation, operation and outcome of an eventual pacemaker insertion in the near future.

    As always, Dr. Mazzini is a wonderful provider. I've been delighted to be associated with him since the first run-in that I had with my heart problems way back when he recommended me down to Dr. [redacted] and they did my ablation and my watchman's procedure. He is spot on with his talk. He always brings it down to the level that I can understand and he is extremely astute. Though an extraordinarily busy individual, He took the time to make sure that I understood everything he had to say. So I would highly, highly recommend this doctor if you ever get a chance to meet him and to use him. He is an extraordinary doctor. Thank you. [redacted]
