DR. Ruby is the ONLY dentist I have allowed to work on my mouth because as a child I was traumatized by an uncaring and unsympathetic dentist. Dr. Ruby is by far the most caring and concerned person even going so far as to help me with a crown that snapped off even though I've been unemployed nearly 2 years and had not dental insurance. I travel from Northern Illinois to see him and will continue until he retired...he better not...still need work.
