4 out of 5 stars

Hartford health care has the technology for cardiology repair or replacement and that is outstanding technology. Cardiology keeps moving forward to make it easier for patients to get help.

He made me feel at ease on a situation I am terrified about, and I have confidence in his skills. A real nice human being for sure.
