Our family has the best dentist! They do such a great job at cleaning our teeth and they are so gentle too. My 7 year old and 10 year old actually enjoy going! No pain or sourness and they leave with a toothbrush, toothpaste, toy, & a sparkling smile. Dr. Bruening is so kind and is such a great listener. We recommend him to everyone.

Our family (my wife and I, our kids, and our grandson) saw Dr. Alan and Diane and now Drs. Andrew and Carissa. We’ve received nothing but stellar care for many years. Chris and the assistants provide the quality service you expect from a family-owned business. They get my highest recommendation!
