Outstanding Physician

Follow up visit was very satisfactory. Dr. Chung was competent, friendly and was encouraging with his prognosis.

Reviewed on Apr 30, 2021

the visit was a waste of my time, so disappointing. a terrible experience as a new patient to Dr. Chung. No vitals, questions, physical exam (listen to heart lungs). I had the printout of my medications and had 4 items to discuss as I normally do with my CC Physicians. He asked me no questions nothing. He was in/out of the room in less than 10 minutes.

Reviewed on Apr 30, 2021

based on this experience I cannot and will not recommend this physician to anyone. He did not listen to my heart/lungs, my vitals were not taken prior to him coming into the exam room.

Reviewed on Apr 28, 2021

Dr. Chung seemed genuinely concerned for my well-being. He homed in on the important parts of the records I brought with me, and let me know what was not included but essential to him, so that I could obtain those items. Dr. Chung definitely went above and beyond what I expected, helping me to make immediate decisions about pressing travel needs. He also arranged for me to see an electrophysiologist who was a trusted colleague in the city of my primary residence.

Dr Chung actually contacted me after getting results from my wearing a monitor!

Reviewed on Mar 5, 2021

Dr. Chung was recommended to me by my primary Atrial Fibrillation cardiologist, Dr. Lawrence Jacobs. They discussed my situation and Dr. Chung discussed options with me. While he is very thorough, he does tend to speak very rapidly, which makes it a little difficult to understand him, but he repeats things for me. He's very kind.

This was my first visit with Dr. Roy Chung, he was very polite & considerate of my concerns as well as the issues I am having with my pacemaker & heartbeats. Assured me he would find a way to resolve the issues. I am very happy to have him as my doctor. I wanted to have my doctor near my home and Dr. Chung at the Strongsville Health Center is perfect. Plus if I need to see him when he is not at the Strongsville office I should be able to see him at the Avon office. It is a little farther to go but still better for me then the Main Campus.
