Hi Willis and welcome....here is a link to a list taht may help you find someone...but be sure and check their credentials and ask lots of questions. It is your mouth and your health and your $$$$ so you have every right to that information.

If you are seeing a ND or practitioner, maybe they could help you with picking a good one.
