5 /5 Craig Theimer: The staff and Doctors at the Jefferson St, Joliet Office are extremely friendly and have always provided me with high quality care. I first found them to remove my amalgams to eliminate mercury and replace with a safer material for fillings. They used extreme care to remove and replace them. I highly recommend this group. Dr Chan is my primary dentist, but I have had Dr Gallo a few times. Both are very personable and explain procedures well. The hygienist (Karin) is very friendly and does a great job. The billing and appointment coordinator has always been pleasant, kind, and happy to help. I have been going to them for 4 years now and have been extremely happy.
