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.

When I do have to go see my cardiologist, I always enjoy this particular Dr., and ALL his staff. I never wait long, and they always listen to everything you have to say..

An awful "doctor". I suffer from acute arrhythmia and had a severe episode IN HIS OFFICE, they did an immediate ekg. He remembers doing it BUT THEY LOST THE RESULTS!! He now claims the attacks "aren't that bad" even though he had trouble getting my heart to stop beating 180+ a minute. I have had these episodes last 4+ hrs at a time and he just blows it off as "not that bad"?

I have been going to Dr. Nathan for years. I highly recommend him to anyone. He spends time with you, explains everything and offers advice that is realistic. It is easy to simply say lose wait and exercise, he goes further and talks about specific things you can do. he is also sensitive to your insurance coverage and cost which is always important.

Dr Nathan is a very good Doctor.He is very thorough and spends time to explain to his patients what is going on.He found that I had 95% blockage in my right artery and had no blood going to the back of my heart.He got me scheduled in for a heart cath. very quickly as my case was urgent.He took time out to explain to my wife where the blockage was at,what he was doing and what was going on. His staff is very friendly,.helpful and courteous. Thank You to Dr Nathan for saving my life.

Dr. Nathan is personable and thorough. You can tell he cares. Four stars because he overbooks his appointments and runs about an hour late on most days. To address the one star rating, yes he has floor to ceiling glass windows that are limo tinted and he has floor to ceiling blinds which I believe can be closed if the customer requests it. Yes some of his exam rooms look more like an exam room with a desk in it. He is that good and that busy, that he has to give up his office for exams.

I was a patient at Memorial Herman SE in 2008. While there I suffered a heart attack and Dr Nathan was called in to care for me. He treated me well at that time and has continued to do so since that time. I am very comfortable having him as my cardiologist and would definitely recommend him to anyone

I have been going to Dr. Nathan for over fifteen years, and have never had any complaints about his care. I've also had two pacemakers replaced in that span and he has always had the best surgeons do the surgery.

This doctor has been my cardiologist for years since he took over practice from my previous cardiologist. He has seen me through bypass surgery and heart failure with an great outcome so far over the last 7 years. I successfully completed EPC therapy with him with good results. I trust him completely.
