  • "Took my kids for the first time and was honestly stressed because my kids are older. I had a fear of being shamed for not bringing them sooner. Instead, the staff made us feel comfortable and welcome. They did a phenomenal job and the kids said it was fun! Thanks for being kind and understanding!"

  • "I have a special needs son and he hates the going to the dentist. Dr. Clapp and his staff are awesome with him! They explain to him what's going to happen before they do it. They are very friendly and open. He doesn't mind going to the dentist now and it gives me a sense of relief knowing he isn't stressed and scared about going. Thank you so much for taking such good care of him!"
