Biofeedback is self-regulated in the United States. There are no requirements to work with the public. Of course, we always suggest that people continue to learn. You can always get more credentials and certifications. There are easy certifications that you can get to be a certified Stress Coach or Wellness Coach. And of course you can always continue your education for instance a homeopath, naturopath, etc. We always encourage you to learn more to be an even better practitioner!
