Dr Berger had a doctor with him who reviewed all of my test and took my info. Analyzed the info with me and deferred final diagnosis and treatment to Dr Berger. He answered all of my questions and was very helpful.

My wife and I had questions which were all answered by Dr. Berger. He did not rush during the visit. He was very informing and took a lot of time answering questions and providing detailed information about a procedure that I wanted to have.

Very impressive and informative. I came to Hopkins from UVA thinking I did not want a Watchman. His patient explanation about my high risk of another stroke persuaded me I could get more protection if I had one.

Dr. Ronald Berger, explained in detail the issues surrounding my reoccurance of afib and the options open to me. He is the same doctor who performed my surgery 17 years ago and was fantastic then and still is. I can't put in words how pleased I am that he is providing me help again.

Dr. Ronald Berger is professional, courteous and kind. He is an expert in this field. He explained the details of the procedure and gave us time to ask questions. We trust him. We met him 10 years ago about the procedure and he wisely suggested then to my husband to be observed and my husband did very well. This time Is different and we will follow his instructions as we trust him. Thank you Dr. Berger.

Dr. Berger (and the fellow who came in before) is an exceptional physician, from the analysis and explanation used for the issue and his respect for my father.

We haven't gotten the test results yet as it's a 2 week test which will take longer for results. Dr Berger is the best cardiologist I've ever met. He referred me to a local provider as he is an electrical heart specialist
