Dr. Byun is a great heart doctor and I am very pleased to have him as my heart provider.
I feel very content in the care I get from Doctor Byun, and feel he does all in his power to keep me healthy.
Other than a long wait after my appointment time, I was treated well, and professionally.
Dr Byun is excellent
Dr. Byun is a very good cardiologist. He is caring and thorough, listens to my issues and provides sound advise, explains the medication change clearly, gives referral to procedures as I requested and makes me understand what the tests are about. I highly recommend Dr. Byun to all my friends and relatives whom might have a heart related illness.
