If I may, I would like to take a minute to comment on the (Patient) that recently gave Dr. Mark Seifert just one ?? and a bad review: You have no idea what you are talking about.

Dr Seifert is a excellent doctor. Not to good on a bicycle though. I bought him a pair of training wheels so he would stop falling off. Really though he did a great job on my surgery even if the the batteries died prematurely. at least I didn't. lol

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...Read More
