Theta Healing modality has relatively recently emerged. It is established by Vianna Sibtal in 1995. She had long journey of suffering as she had serious sicknesses as cancer but all cured once she made the healing on herself.
Vianna has successfully merged a modern concept with an aged faith. To clarify, theta healing concept is new but the believes around it is very old. For instance, Theta healing uses very modern technique called digging work to reach to the root limited believes and change it through healing process trough the creator of all that is (old faith).
