On 11/21/2024 Bryan (Joliet, IL) had this to say:
I have been going to John for around 20 years. For me it's non-negotiable, I will not go anywhere else but to John, as long as he is in practice. John & his staff are all friendly, nice, gentle and fun! When I talk dentist stuff with friends they will often say " I want a dentist who can give service with no pain." Well today I was at his office & had 2 fillings-- no pain at all! Another thing about his office is they do it the right way. They do not over book a time slot, and make you wait an hour to get in. If your appointment is at @ 2:00, You will be called from the waiting room at 2:00. Speaking of the waiting room the facility is nice, clean, modern and is located at a safe location. If you need a dentist go here, you will be treated like family... Bryan~
