I went to Dr. Xa because he accepted my insurance. When I arrived for my early morning appointment the staff was late opening the office, forcing me and another patient to wait outside. My initial appointment was not bad, but when I returned to have 2 cavities filled, the Doctor was rushed and did not seem to care that I was in pain. When I asked for more novicane he seemed put out by my request. While the dental work turned out fine, I will not return in the future.
