I've been seeing Dr. Kats since he started with the practice in Downers Grove - at least 15 years. I have had a lot of dental work and see him 3 times a year for cleaning and check ups even though my insurance only pays for 2 visits. He has done restorative work on my front teeth, which are crowns, that made me happy to smile again. His crowns ALWAYS fit wonderful and you can't tell they are there. He is patient and professional and the office staff is a pleasure to work with. I highly recommend him and many members of my family have gone to him for years and years.
