Founders & Authors

ThetaHealing® was developed by practitioner and author Vianna Stibal in the mid-1990s and formalised through the ThetaHealing Institute of Knowledge (THInK). At the intersection of meditation, intention, and belief work, the modality is taught through a structured curriculum and certification pathway.

Vianna’s books outline a framework for identifying limiting beliefs, accessing the theta brainwave state, and co-creating new patterns with the client’s consent. The method blends guided meditation, muscle testing, and inquiry, giving practitioners a clear, repeatable process.

Joana Castro is a certified ThetaHealing® practitioner who integrates the modality with mindfulness facilitation and energy work. Her practice emphasises clarity, gentle pace, and client empowerment, aligning spiritual tools with real-life goals at work and at home.

Why Was It Created?

ThetaHealing® was created to offer a teachable approach to change without requiring clients to relive pain or trauma. Working in the theta brainwave state, the technique aims to uncover core beliefs, release limiting patterns, and install supportive programs aligned with the client’s values. Designed to complement—not replace—medical or psychological care, it provides a structured pathway for practitioners and a considerate experience for clients seeking clarity and emotional balance.

How Does It Transform?

The ThetaHealing® technique helps clients and practitioners achieve meaningful shifts by working at the subconscious level in the relaxed theta brainwave. It is structured for personal growth and professional practice, making it accessible and effective for a wide audience. You don’t need to follow a particular belief system to benefit; an open mind and willingness to participate are enough. Combining guided meditation, muscle testing, and belief mapping, the method uncovers root programs and gently replaces them with supportive patterns, creating change that is clear, grounded, and sustainable.

Why Does It Matter?

Unexamined beliefs can surface as stress, self-doubt, or repeating conflicts. These subconscious “imprints” often drive automatic reactions—anxiety, perfectionism, avoidance, people-pleasing—or keep goals stalled through procrastination and fear. Even persistent tension in the body or sleep disruption may reflect patterns learned long ago. When left unaddressed, these scripts shape decisions, relationships, and daily performance without our awareness.

Through Theta Healing sessions and practice, you will consistently:

• Identify and rewire core subconscious beliefs.

• Build a clearer connection with your inner guidance.

• Integrate change with practical, compassionate daily actions.

What Language Is The Session?

The ThetaHealing® technique is a universal form and is only given in the language of the Practitioner. Joana speaks four languages; however facilitates the sessions in either English or Portuguese.

What Happens In A Session?

We start with a brief intake to clarify your goals. You’ll be guided into a relaxed theta state, then we use gentle inquiry and muscle testing to surface core beliefs. We release limiting programs, install supportive ones, and close with simple integration practices you can use after the session.

Is Theta Healing A Replacement For Therapy?

No. Theta Healing is a complementary modality and does not diagnose, treat, or cure medical or psychological conditions. It can be used alongside therapy or medical care; always follow the guidance of your licensed healthcare provider.

Why Is There A Prepayment?

The prepayment is requested as a small step towards confirming your commitment and investment in yourself. You’ve already taken the first step to liberate yourself by being here in this moment, reading this message.

How Many Sessions Will I Need? 

Many clients experience noticeable improvements within 1–3 sessions. Complex or long-standing patterns may benefit from a short series. We’ll agree on a cadence based on your goals, with space between sessions for integration.

Do you offer online/virtual sessions? 

Yes. Online sessions follow the same structure as in-person. You’ll need a quiet space, stable internet, and a device with audio and video. After the session, you’ll receive tailored integration steps.
