Dr. Meisler is very wonderful. He takes care of my sister and a couple of my friends. When I had to go to him because of a heart attack, I was very happy that he was my doctor. But I recommend him 102%. Thank you so much, Dr. Meisler.

What else would you like to say about your experience?
The staff were polite. The nurse, and Dr. Missler were very easy to talk to. Dr. Missler’s personality made me feel comfortable, not rushed, and he explained things to me I wasn’t aware of. I have been to many doctors in my lifetime, and have found some were not personable, and not trustworthy, but I was happy to find Dr. Missler one to whom I believe I can trust. My first visit there with this doctor, I found all were very polite.

What else would you like to say about your experience?
Dr. Missler is probably the most competent cardiologist I've met since moving to St. Louis. And also, he listens to any questions that I have, or if I don't understand something he's telling me and I ask him to repeat it, he will do so easily. And also, he's a very good conversationalist, and I would recommend him to anyone.

What could have been done to improve your experience?
The doctor did not explain test results. The doctor did not take my symptoms seriously and seemed to make his mind up without listening to my concerns. No arrangements were made for timely follow up. I left feeling misunderstood and with no treatment to alleviate my concerns. The doctor was polite and friendly but not helpful.
