How likely are you to recommend Dr. Byun?

(Select your rating)
I met with Dr. Eugene Bynun at Providence St Jude based on the recommendation from my cardiologist Dr Jay Han. Dr. Bynun spent about an hour with my wife and I explaining everything about my situation, saying that I could be a potential candidate for the less invasive TAVR surgery (which they go through your groin which he does this surgery) in lieu of open-heart surgery which is more invasive. But he also told me based on my health and age (71) that open-heart surgery is what he recommended and proceeded to explain to my wife and I why. He was terrific and I really felt it was easy to make this decision after listening and talking to him that day. If you ever needed TAVR surgery I would highly recommend him based on my experience with him. He is very thorough and takes all the time with you as needed.
