Garden Grove, CA |
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.
Mission Viejo, CA |
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.
