After discovering a way to heal her body from cancer in 1995, Vianna Stibal pioneered and refined the method, and referred to it as Theta Healing®. Since then, she has founded the Theta Healing® institute of Knowledge and wrote many books about Theta Healing®, and formed classes for people to learn this life changing technique.

The ThetaHealing Institute of Knowledge (THInK) is dedicated to the certification of ThetaHealing® Instructors and the development of ThetaHealing® United World Wide. ThetaHealing® is an energy-healing modality founded by Vianna Stibal, based in Ammon, Idaho.
