A pediatric dental practice a five-year-old asks to come back to

I'm a pediatric dentist opening my own practice in March after ten years in a group. I want the whole world designed so a five-year-old asks to come back and a parent trusts us before we speak: the name and identity, the wall kids remember and tell their friends about, the welcome materials, the goodbye bag that's the best part of their day, and the words for the website. The bar is what the best children's museum would do if it did teeth — wonder first, clinical excellence visible underneath. I budgeted real money for this because it's the one thing dental school never taught, and every pediatric practice in this city looks like an insurance office.
