Dr Rainbow Chung-Ou is awesome. Definitely helps that her office is very close to my house and that she's very helpful with consultation by phone as another option. I've had anywhere from skin problems to sinus infection to flu and she always knows how to get me back to feeling better again!

I told her nicely that chino office said everything is cleared, I actually don’t owe them anything ther... read more
