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.

Awful doctor, and his staff are just as horrible.
This man will give you the bare minimum of time and his follow up skills are horrible. If I hadn't gone to see someone else, I would not be here today. Changed my meds and when I called multiple times to discuss my symptoms, I was treated as an inconvenience. Thank God I went for a second opinion. Most of his staff at each office reflect his leadership. He will see nice at first, but you will catch him on the verge of flipping out on a staff member. Stay away!

Dr. Covalesky is the best cardiologist I have seen (and I've seen quite a few). He is friendly, attentive, and cares about you as a person. He manages my dysautonomia and is very knowledgeable about it. He will work with you to make sure you get the best treatment possible and he always explains things clearly.

More Than A Number
I first met Dr. Covalesky when I was hospitalized as a result of being overmedicated for high blood pressure. As my organs began to shut down, Dr. Covalesky reversed the process; and I can only say that his expertise literally saved my life. That episode left me with an electrical abnormality for which I see Dr. Covalesky regularly. Here's my assessment from many office visits: Highly recommended. Courteous, efficient, and professional office staff. Short wait times. Dr. Covalesky is personable, thorough, and communicates well by using common language, rather than unfamiliar medical terminology. He takes the time to fully explain tests and procedures and how the results identify my needs. One of the very best doctors I have ever visited; he treats you as person, not just a patient number or a particular medical condition. I'm sure lots of doctors are qualified to provide the care I need, but I appreciate the fact that Dr. Covalesky treats ME, not just my heart condition.

The nicest office staff and doctor that I’ve had to visit in recent months! Would definitely recommend this office. They were able to accommodate me on a very short moments notice, without an appointment, to get pre surgical clearance ...and this was on a Friday afternoon!
