Do I have to get certified to be an Acutonics sound healer?

No. You can begin to use the knowledge and techniques right after class. You just cannot legally call yourself an Acutonics Practitioner or any of the certification titles awarded to students who complete the certification track of classes. You can use Acutonics focused sound healing or integrate it into your own modality after any class. Official Acutonics Certification Titles & Requirements
