Dr Seifert not only saved my life but improved the quality of it also. He is a caring Doctor with wonderful people skills and great bedside manner. He is always available for serious matters and his nurse Terry is the best. If you want a great Cardio Surgeon, this where you belong. Thanks Doc Steve M. Phoenix

Excellent Electrophysiologist!! He is not overly arrogant and dismissive like others I have seen. Dr. Seifert is very knowledgeable and listens, he is my favorite Doctor so much so that I drive over 3 hours to see him.

The condition I was referred to Dr. Seifert's office for was apparently trivial and not worthy of his consideration. Dr. Seifert asked me (in a wondering tone, in front of two skinny, wide-eyed interns) how it came about I had been given his name? I was uncomfortably situated up on the exam table without my shirt or glasses (I am moderately obese and feel vulnerable around thin people) answering a barrage of rapid-fire questions for several long minutes. I will not be returning to his office.

Dr. Seifert fixed my heart of AFIB event while in Phoenix. First time I have a regular heart beat -- no skips or sudden rushes of beats. He went out of his way to explain the procedure, why he was recommending it. [ALSO, the side effect of the AFIB was the accumulation of water. He doubled the dose of Furosemide to trigger my body's water loss functions - it worked, and the thirty pounds was lost in two weeks.] He is praised by the coworkers, nurses, and staff of the hospitals and offices.

I have been one of Dr. Seifert's patients for almost 11 years. I am SO thankful for his amazing knowledge, skill and sincere compassion and care. He takes such wonderful care of me and is always available if I have an emergency issue or question. If you are looking for a cardiologist that can answer any question you have, will treat you with the utmost respect and kindness and is always there for his patients' needs, Dr. Seifert is the perfect choice!!

He diagnosed and treated my husband immediately after he had been treated and underdiagnised by precious Dr's. He performed two different procedures. He is extremely intelligent and skillful as a surgeon. He gave us his personal cell phone number to contact him in emergencies. I highly recommend him.
