    Dr Loeser was referred to me and even though it can be tough changing Dr's ( I was so unhappy with my former dentist) I am thrilled I made the change. He is top notch and has a wonderful personality as does the entire staff... really like them all, and it makes it easier to go.
    Highly recommend!
