An excellent provider and a very good experience. Would highly recommend this provider to anyone with cardio concerns....

The care provider was very courteous and everything was on time and I would only say good things about the people. The issue that I have isn't really so much that, it's that I really didn't get the answers that I was looking for in terms of my current situation and how I can improve on my current situation from where I am today. That was unclear to me coming into the meeting and it was still unclear to me coming out of the meeting. And maybe that's just the way it has to be. Thanks.

Excellent care

This doctor came in the room without a greeting or introduction. At first, I didn't realize that he was the actual cardiologist because of the way he came barging in straight to the computer without a word. The doctor never even made eye contact. He rushed through the visit the entire time. After he ordered some testing, he told me to follow up with my previous cardiologist. Awful bedside manner overall.

I transferred my care after a change in insurance and needed someone with expertise of my chronic condition. I was matched with this provider and felt he had a wonderful bedside manner. He listened intently, asked thoughtful questions and offered good advice when we talked about my concerns. We made a plan together that put me at ease.

Provider really did not show much interest in me or my concerns. It appeared he would rather be doing something else and when I had a couple of questions it seemed I was keeping him from leaving the examination room. He read the numbers to me, but that probably could have been done with more care and explanation by a medical student.

He seemed a bit impatient. Did not want to be interrupted with questions while he was talking. When I asked for additional measurements to be included in my blood test, he seemed a bit bothered by my request. He did not give me any feedback on the ECG measurements that had been taken previous to our meeting. He prescribed tests but did not explain to me the reason for the tests, particularly the nuclear stress test.

Dr. Jang has been my "heart" doctor since 2008 when I had an arteriography type procedure, result as I understand it is some blockage controlled by medication, monitoring etc. Dr. Jang seems "rushed" during my visits, is not loquacious and I understand it is what it is. Not a lot of verbal interaction but my last takeaway was heart looks OK or something like that. In the recent past, I was seen by a Nurse Practitioner and then by the Doctor; more exchange during those visits. Now I guess it is the Doctor visit only. With my condition staying stable the plan is working.
