I went to Dr Quans office twice so far. Free consultation was informative and Dr Quan was friendly and open to questions. I also had exrays and returned next day to start adjustments. All I can say so far about said adjustment is that it immediately took my pounding headache away that I awoke with because of neck pain. Because of this I plan to continue my sessions. Another reason for staying with Dr Quan is that she saw me ON TIME which I have not experienced too frequently!!
