Get to Know
Dr. Alex Otto
As the Founder of Kids Tooth Team, Dr. Alex’s goal was to create a pediatric dental office unlike any other. After nearly a decade of being in the profession, it became clear to her that dental offices were becoming more and more about the doctor and insurance companies and less about the patients and the families they serve.
Dr. Alex hated seeing families waiting forever to see the doctor, only to be told that there was only one way to do things (the doctor’s way of course!). It drove her crazy to hear sales pitches or anyone recommending unnecessary treatment, especially to a child. And not to mention the lost look on a parent’s face as some random person in the office confusingly tried to explain an insurance plan or how much you may owe - they may as well have been speaking a different language. She knew that Kids Tooth Team had to do things differently.
