Always a pleasure the staff in very helpful.

I always appreciate my appointments with Dr. Keller; he is very compassionate, knowledgeable and always takes time to discuss my health concerns.

Dr. Keller is a caring provider. Not only does he call you back with results, he answers your questions. Unlike most doctors today who have a nurse practitioner answer the questions and call you back, Dr. Keller calls you back directly, which is a very, very, very important thing to have as a doctor. So it's much appreciated.

Trust his judgement totally

Dr Keller is a great cardiologist and knows what to do and has a great "bedside " manner. His staff is very good and treats you with respect.

Dr Keller is an excellent doctor!

Have been a patient for 20 years and I'm very satisfied. Thank you

Dr. Keller listened to me, he answered all my questions. He's just a very, very good doctor, I feel. And he knew my circumstances and he read my report and everything was very good. I was very happy. I would very much recommend him.

We are totally satisfied and have been for many, many years with Dr. Keller. Thank you.

I've always been very impressed with Dr. Keller. He's a wonderful doctor and we have been going to him for several years now.

were happy with the provider.

Doctor was knowledgeable and caring.

Yes, he's a very great doctor. I had him for forty years. He's the best doctor I ever had. Bye.

Dr Keller was very thorough discussing my diagnoses from my recent hospitalization. He also ordered 2 additional tests to be done before I left the office to define the prognoses more clearly for my understanding and a course of action if needed.

Dr Keller is the best!!! One of my favorites-good listener- caring, honest,helpful! Going to miss him as he retires in Oct!!!

I was 20 minutes early and I was taken 18 minutes quicker wow. Impressive

Dr Keller is a wonderful doctor and had provided excellent care to me for many, many years.

The personnel and doctors who work at Raritan Bay Cardiology are the best they were very kind and do their best to answer any questions you may have. When I last visited, I did not have any questions at the time but I know I can always call and ask a question, and I know I will receive an answer.

I've been visiting Malvin Keller for many, many years, and I even took a moment to compliment him at the appointment, to tell him that he's very, very conscientious, and he's very thorough, that's the word, very thorough, and I'm very comfortable with him, and he always guides me through any blips in my health and all that. Thank you.

Yes, hi, Dr. Keller is a wonderful doctor. He has always given us the ultimate in care and service. And he's a very caring guy and a wonderful doctor. And we really appreciate his services. Thank you.

Dr Keller will be retiring and i will be sorry. He is great

My Provider is Great

Dr Keller is the best doctor I can think of. He is caring and extremely knowledgable.

Dr. Keller is a cardiologist. Every time I have gone to a cardiologist, they do an EKG. That was not done. When I asked about having blood drawn, I haven't had blood drawn all year. He advised me to see my primary. I didn't feel as though this was a complete office visit. I was rather disappointed. I need to have an ultrasound of the carotids. Previously, they would have a technician that came in once a week. Now they're telling me the technician doesn't come in until the evening. So I have to go to two other locations, which is a terrible hardship for me because I do not drive. It was a very, very disappointing appointment. And I'm questioning, should I see another doctor in the practice? Why have things changed? Did he forget to have an EKG done of me?

Dr. Keller is retiring. We will miss him greatly.

Dr. Keller and his staff were very professional and friendly. my visit was to obtain medical clearance for spinal surgery that I will have next month. everything was finished in a timely manner. DR. Keller asked how long I would be out of work. I told him that they said 2-4 weeks for initial healing and therapy, and about 3 months to be back to normal. Dr. Keller told me "DO NOT RUSH BACK TO WORK" make sure you are able to handle driving that far every day, and your able to sleep normally first. Thanks Doc
