everything was very good
As I stated earlier, Dr Byun is absolutely one of the best doctors I have ever had. He really cares about his patients.
*Dr. Byun is an outstanding man & surgeon. He spends quality time with patients, answers questions and makes you feel at ease. I am alive today because of his skills & timely intervention.
Happy so far
Provider went above and beyond to assist in securing desired medication. Not currently available through local pharmacy. Set up mail order account.
