Dr. Bui's English leaves a lot to be desired but he can understand what you tell him and usually fixes it. I have been going to him for years for the occasional kink that comes up.
He does not worry much about reaching areas that most folks keep covered for ordinary modesty, but I have never felt any discomfort with this. He just does what he needs to do.
The salve he uses, Sombra, is very good but it is also very strong scented--camphor and menthol, in case you take homeopathics. And he has jars of it to sell and it's pretty inexpensive.
And, as chiropractors go, he is very moderately priced.
