    I've never had surgery before so I was a little nervous but Dr Preston took time to explain about the surgery and didn't rush me or my questions. If I don't feel comfortable with a doctor I will leave but I believe I am in very good hands with her and by the end of the appointment I had made my decision to have the procedure done because of her
