Out of 27 years of working in the medical field, Dr. Byun has been the far best Dr. And Cardiologist that I worked with. He was very knowledgeable, thorough, nice, professional, and honest with his patients and staff. I enjoyed working with him and I loved his open-mindedness regarding stress management and medical meditation I used to discuss with him and patients. I've now been a medical assistants for 11 years and have great memories at St. Jude and Dr. Byun! Thanks for being a great Dr. !
