The very best! Been coming to Dr. D for years. Most professional, highly skilled dentist I've ever known. His attention to detail, patience and care is unmatched. So glad he sees my entire family. Amazing, wish I could do 6 stars!

My husband and I have been coming to Dr. D for over 10 years now. We even moved houses and have to drive much farther to get to him but have never considered switching. He's so enjoyable to talk to and has a very caring manner. We have our favorite hygienist, but have liked all of them that we've seen. I'm impressed that they regularly add new and advanced screenings. They genuinely want to provide the best care they can. My visits are always relaxing and enjoyable.

This was probably one of my best dental experiences ever. Had to have a cracked filling replaced I got in and found some decay. They remove the decay read it I knew filling and it was painless. I would strongly recommend anybody looking for an awesome dentist in the St. Charles county area to go to Monticello Dental.

I can't stop saying great things about this practice. Amazing, dentist, staff, facility! Everyone is warm welcoming courteous. They always above and beyond for you. Checking with insurance to fighting for you when they feel the insurance should have paid more. Amazing service and care! They are there for you if any kind of treatment outside the norm is needed and let you know your options before anything starts. Pain Free cleanings! They make me not fear going to the dentist, i look forward to it! I will always go back!

I've been a patient of Monticello Dental for the past 10 years. Their office is run very efficiently and appointments are always on-time. Dr. D is great, very gentle, caring and personable. The dental assistants are very pleasant, efficient and also gentle. I've never had a bad experience here. I have recommended Monticello Dental to friends who are now Monticello Dental patients.

My family changed dentists a couple years ago or so to Monticello Dental. I was totally impressed. The dentist and his staff are just super! I have never had a dentist that has been so attentive. It is a nice switch! I have recommended him to friends in the area.
