My kids LOVE going to the dentist! Everyone at Dr. Doug's office is so nice and helpful. They love playing mario kart right from the comfy chairs during their checkups and look forward to going to the dentist! Dr. Doug is super knowledgeable and has helped us with so much, including advice for getting our kids to quit thumb sucking, routine checkups, and a few emergency knocked teeth checks. He also takes time to discuss everything and makes sure you leave with all questions answered. I highly recommend taking your kids here for any dental checkups!

We have been taking our kids to Doctor Harrington for 11 years now. All four of my children absolutely loved him and his staff. His staff is very nice and so good at making the kids feel comfortable. It's wonderful that Dr Harrington is a dentist and an orthodontist. Now we don't have to go to two different places once our kids are ready for their Orthodontics. The front office staff is so sweet and I've never had a problem with my appointments or scheduling.

Dr Harrington and his team have provided our son with excellent pediatric dentistry for the past 8 years and orthodontic care for the past 2 years. Very professional and always made sure we understood the next step in our son's orthodontic treatment. Office was always accommodating to his school schedule. We highly recommend Dr Harrington.
