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.

Happy National Doctors Day

Outstanding cardiologist!
I found Dr. Johnson to be professional, yet friendly and engaging. What surprised me was that he had read my patient file thoroughly before ever seeing me which I find unusual these days. He took his time and explained things in layman’s terms while answering all my questions and concerns. I highly recommend him for any cardiac concerns you may have.

Dr. Johnson used to be good, but it's almost impossible to get a timely appointment with him. Dr. Johnson told me to schedule an appointment soon in the future and they could only give me an appointment 2 & 1/2 months later. Then they cancelled that appointment and gave me a future date without even notifying me! Then they called again a week after that to tell me Dr. Johnson would not be in on that date. The practice itself is rude and condescending in my experience. I got a new doctor. Enough!

I/we have had positive experiences with Dr Johnson. I and my husband are fortunate to have him as our cardiologist ; we feel secure in knowing he is always attentive to you as a person and knows what you require as an individual. He was recommended by a well known cardiologist who had just retired and, in fact, had been my parents cardiologist ...We knew we would be in good hands with Dr Johnson.

My husband and I both would recommend Dr. Johnson to any of our close friends and family! He sees both my husband and myself and we feel very lucky to have found him in the crazy carousel of health care. We luckily have found a competent, caring man who listens to what ails us and tries to make the most of his time with us while addressing our every issue. My husband and I are both Auditors and have made our living assessing people in different situations and this is a man we really trust.

I cannot say enough good things about Dr. Johnson. He's friendly, personable, and always knows just how to explain things so they make sense. He treats you like you're more than just the next patient on his calendar and actually spends time with you to talk about your questions and concerns at every visit. I would highly recommend him to anyone who is looking for a cardiologist.

I was very happy with Dr. Johnson , his staff and the overall office environment. Everyone is helpful and they return your calls and patiently answer my questions. Dr. Johnson was so compassionate and understanding while I was going through one of the scariest situations in my life. He took all the time needed to ensure I had answers to my questions and treated me like a person and not a "case." I have had a great experience with them in the midst of a medical crisis.

It is my pleasure to write a review regarding my appointment with Dr.. Alexander Johnson at the Heart Institute.. Not only was my appointment very professional, but Dr. Johnson called me prior to the appointment to tell me the results on my echo. During and after the exam, he explained his findings in such a manner that a lay person could fully understand.
