I absolutely love Eastside Pediatric Dentistry! Everyone is so nice and they were amazing with my son. He is almost two years old and they gave him things to do while we waited to be seen by Dr. Mast. The hygienist were so sweet and so good with my son. They let me son “help” them with cleaning of his teeth so he didn’t freak out which I thought was amazing and made the appointment so much smoother! Dr. Cody Mast was absolutely amazing too gave me some really good tips with brushing teeth and just made me feel like I’m doing a good job! I would recommended everyone going there because they are AMAZING!!! I’m so happy I found them for my son!Posted on Google

Super friendly staff and very homey environment for the kids. Our 3 kids were a bit nervous when they went in for their cleanings and checkups but were soon put at ease and had a great time. Their dental needs were all taken care of professionally and they are even looking forward to their next visit! Highly recommend Eastside Pediatric Dental Group.Posted on Google
