May 23, 2020 7:23 AM

I trust Dr RAmanathan completely

May 22, 2020 2:13 PM

Dr. Ramanathan is a very caring, concerned cardiologist we always asked _____ as on my health, advises me on issues.

May 22, 2020 2:13 PM

May visits to see Dr. Ramanathan has always been very pleasant.

May 22, 2020 2:13 PM

The call was prompt - on time with office. However, after the med. assistant questions, I was told the MD would be with me in 1/2 hour. SO, even though I was scheduled, the whole office visit - telemedicine took 1 1/2 hours. It would be better if it was a shorter wait.

May 19, 2020 11:13 AM

Outstanding. Dr. Ramanathan is excellent

May 19, 2020 11:13 AM

First class

May 18, 2020 3:42 PM

Due to the Corona virus sheltering at home situation, this was a visit via Zoom (over the Internet). Thus, I was unable to be examined. I was able to ask Dr, Ramanathan questions I had stemming from my heart surgery (aortic valve replacement and bypass) on 2/14/2020. Dr, Ramanathan explains things clearly. He speaks distinctly, with a strong clear voice which is very important for me as I am hard of hearing. He is very respectful and seems caring. He never acts impatient or condescending. I have had the opposite experience with other doctors (NOT in the Advocate group).

May 18, 2020 3:42 PM

Dr. Ramanathan is always very pleasant.

May 18, 2020 3:21 PM

Because of the virus that the country is experiencing, the visit with the Doctor was done by a video conference. This was very easy and a great experience.

May 11, 2020 2:51 PM

DR covered every questions I had and he went through my medical history. I was a patient of Dr. Larkin and was transferred to Dr. Ramanathan s care. He is very pleasant and easy to talk to.

May 7, 2020 8:39 AM

Due to necessary surgery Dr. Ramanathan was referred to me. I'm very happy with Dr. Ramanathan and will continue to see him as my cardiologist.

April 7, 2020 5:19 AM

This was an unusual visit (on the phone) with my cardiologist. Since I never actually saw him because of the COVID outbreak. However, he tried to address my concerns to the best of his ability under very challenging circumstances and I am certainly grateful for that.

April 4, 2020 10:27 AM

Due to the virus this was a phone visit to avoid catching the virus in the hospital where the Doctor's office is. I like the Doctor and think he is good. I see him yearly for my heart. I did have an appointment but we had to do it by phone. It was my yearly appointment. Sorry if I put anything not positive. I think Dr. Ramanathan is a great doctor.

March 17, 2020 1:02 PM

As usual things were very good. He always asks my opinions and takes them seriously.

March 17, 2020 1:02 PM

He is always very attentive and personable.

Dr. Ramanathan is my husband's doctor, and I saw him several years ago. I find him highly skilled, a good listener, and very empathetic. We are fortunate to have him in our lives!

February 27, 2020 11:00 PM

Everything went well.

February 27, 2020 9:50 AM

Very helpful. Good advice.

February 10, 2020 7:22 AM

Very good.

February 10, 2020 7:22 AM

Pleasant experience. He told me he was concerned about my obesity, and wants me to lose some weight by stopping eating fattening foods, and to exercise more - I'll try.

February 5, 2020 9:35 AM

I was not rushed. I am always made to feel more like a friend than just a patient which makes it easy to talk about any heart issues I may be experiencing.

February 3, 2020 10:49 PM

Dr. Ram was very professional and I enjoyed ur visit.

January 6, 2020 2:12 PM

Otherwise this provider is an excellent cardiologist.

December 26, 2019 9:50 AM

Excellent. He listens and gave me time to talk about my health.

December 23, 2019 11:31 PM

Dr. Ramanathan is a very good doctor. I felt that nurse who saw me did not know any thing about me. It was not a good.

December 16, 2019 4:50 PM

December 16, 2019 1:39 PM

Dr. Ramanathan always tries to help me.

Went as expected; I have been with Dr. Ramanathan for some time now, and I both trust and like him.

October 27, 2019 7:00 PM

I was there on a referral from my Primary doctor. I can honestly say the doctor was excellent. I was able to ask questions and he helped me to understand certain causes of heart conditions. I felt very at ease once I talked with him.

October 27, 2019 7:00 PM

Dr. Ramanathan is an excellent doctor. very professional, and cares about you as a person. I have total trust in him.

July 21, 2019 7:00 PM

My 2 favorite and most respected physicians referred me to Dr. Ramanathan. As a surgeon's daughter, I expect integrity (at the very least) from my doctors. I add Dr. Ram to my very short list of doctors & specialists who have that character trait these days. I am very happy with him and view him as an excellent doctor.

July 14, 2019 7:00 PM

May 5, 2019 7:00 PM

I was originally scheduled for the yearly checkup on Friday April 26 but your office changed it because of the change over to the new system. I do not understand how this could happen.
