The lab test results came out bad. There were 6 flags and one of them has critical warning. I expected to hear detail explanations from Dr. Byun and appropriate treatment. However, Dr. Byun simply said everything looks good to him and nothing to worry about. In addition, he said I can choose to have bone marrow test if I want. He didn't explain anything about the test results and rushed to finished the session. His attitude was really bad and it made feel very uncomfortable. The session lasted about 5 minutes. He seems very ... read more

I left the office after seeing Dr Byun yesterday and felt really hurt. Every question I asked he rushed answers and it felt like he didn’t care at all. My diagnosis of pancreatic cancer is grave but after I asked the question, I learned I’m at stage 3 so in my mind there is hope! But he didn’t give me any hope and spoke to me just like another one of his many patients. If I hadn’t come with my list of questions, I wouldn’t have received anything out of him.

My mother had breast cancer, and I have heard a good reputation for Dr. Byun, so I made an appointment.

The staff at the desk is the first people patients see and talk to, and if their b... read more

Dr Byun is so caring and compassionate. He is also upfront with what can and cannot be done. He clearly laid out our choices and then made his recommendations. He answered all of our questions, and we never felt rushed. He is like this with each visit! You feel cared for by him. The general office staff; billing, scheduling, front office, needs to take a few lessons in manors, but I've seen worse. Ultimately I am not there for them, I am there for him.

Worst bedside manner. Very little sympathy. Not knowledgeable about latest treatments. Not sure why he is in this field. Would have been a great accountant.
