Dr. Guo is a highly knowledgeable and competent dentist, truly a master at dentistry. I was fortunate to discover her a year ago during an emergency. She will go out of her way to take care of a patient with an emergency even leaving her home on the weekend to meet a patient at her office. How often do you meet a caring kind dentist? In the past I have had to deal with dentists who are incompetent, rude, rough or uncaring. I'm grateful to have found Dr. Guo!
