Hinsdale Denistry is the best! I live out of state and come twice a year just to see Dr. Harnois and all of his amazing dental assistants. Today I had Wendy and she cleaned my teeth thoroughly and without any pain or discomfort - a true professional!

Dr. Kowalczyk and his staff have been more than accommodating and helpful with all of our dental needs. He explains everything thoroughly, and the staff is friendly, nice, and knowledgeable about everything from appointments to procedures. Highly recommend this office!

Dr. Michael Kowalczyk and the entire staff at Hinsdale dentistry are great! Everyone is personable, punctual, professional, and the quality of their work is superb. They have treated me for routine cleanings as well as procedures with excellent cosmetic results. I have known Dr. Mike for many years; he is a great doctor and person. I highly recommend Hinsdale Dentistry.

Very kind and gentle dentistry. Hygienists are thorough and caring. Dentists provide excellent treatment and only when necessary.

I came in two years ago and got 18 Panera. Done by Dr. Peter, and the experience was absolutely the best. The staff at Hinsdale dentistry is absolutely amazing best experience with the Dentist I’ve ever had.

I had my 6 month appointment today and was once again reminded why I love these guys so much. Even during the years of my more serious dental needs Peter and his staff always made my visits a pleasant experience. There’s no one more thorough and caring than Peter and his staff. He makes it a point to visit and check my status and approach to maintenance even when I’m in just for a cleaning. They are all passionate and dedicated to their work. From the arrival to the completion of my visit the entire staff makes patients their focus. Dr. Peter Harnois and his staff consistently receive a 5 star rating because they deserve it. Thumbs up guys!

As good as it gets! The staff are consistently welcoming and patient focused. Heather is the BEST! Great skills, responsive and friendly. Dr. Harnois is the consummate professional. See you again in November.

Could not be a better dental experience! Great doctors and staff. Wish all healthcare providers were like this!
