Doctor Liebman has done all of my dental work for the last ten years, including a number of fillings and crowns. In that time, the work has been high quality and pain free. Costs have been reasonable and I have never had any problems with their handling of insurance claims. Staff has been knowledgable, friendly and attentive, always making time to answer my questions. I would happily recommend this dentist to other patients who are looking for a dentist in the Chicago area.
