Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

I am happy to have an Exceptional Cardiologist
Dr. Siegel is an exceptional doctor because he is easy to talk to and understands the importance of quality of life. He answers all my questions thoroughly. After my cardiologist of twenty years retired, I tried two other doctors before finding Dr. Siegel. His excellent staff goes out of their way to make patients feel comfortable, and no question is ever ignored. Although I live forty-five minutes from his office, I am not looking for anyone closer because I know I am in great hands with him.

Annual check up
Dr. Siegel is AWESOME. He takes plenty of time to ask you how things are going. He never rushes you out. Very few doctors take the time to treat & make recommendations to you the patient without making you feel you’re just a number. Look no further he’s a Great doctor & a wonderful human being.

Great First Meeting with Dr Siegel
I truly enjoyed my initial patient session with Dr. Siegel. My cardiologist had left Honor Health so I needed to establish myself with another doctor. I was impressed by his manner and openness, as well has his wealth of knowledge. His staff set me up with Dr. Seifert, Electrophysiologist, as my pacemaker batteries are nearly depleted, and he also answered several questions for me. I was also set up to return in two days for a pair of tests as Dr Siegel had seen some things in my pacemaker upload data that he wanted more review of. I felt like I was already a patient known to him for some time.
