1 /5 John Knudsen: Dr Yun saw my daughter today and he is very rude. He never introduced himself when he walked into the room but first started out with she is fat and needs to lose some weight. My daughter went to see him for bladder infection and sinus infection. It would almost think she was going there for a weight-loss clinic. Having the Doctor stay on task was a little difficult as he was only focused on commenting on her weight. He should be ashamed to call himself a physician. We now have removed our family from TCCH.
