THETAHEALING® CERTIFICATE OF SCIENCE TEACHERS

Meet Our Theta Mastery Team

Each teacher here holds the Certificate of Science and years of hands-on expertise. Together, we deliver transformational training with precision, presence, and power.

Founder Errol Campbell

Errol Campbell was the very first ThetaHealing® practitioner in the UK to receive both the Master Certification and the prestigious Certificate of Science — a pioneer who laid the foundation for the modality’s growth across the country.

He established the UK’s first certified ThetaHealing® school and hosted Vianna Stibal’s earliest teacher trainings on British soil.

With over 20 years of experience, Errol has taught thousands of students across the UK, Europe, Southeast Asia, and North America. He has built personal development businesses in the UK, Bali, Thailand, Malaysia, and Canada — and has guided clients through profound transformations in health, relationships, career, and purpose.


His reputation extends across industries and borders, having quietly supported spiritual leaders, public figures, royalty, and high-level coaches. Whether helping someone overcome a health challenge or unlock financial freedom, his approach is deeply attuned, grounded, and precise.

Though his teachings are rooted in the original ThetaHealing® methodology, Errol’s depth of presence goes far beyond the curriculum. He holds a Diploma in Spiritual Counselling, a Certificate in Spiritual Life Coaching, and advanced training in NLP, hypnotherapy, breathwork, energy healing, somatic integration and 20+ modalities.

His teaching is spiritually grounded and trauma-aware, creating a space where safety meets deep energetic breakthrough.

Errol’s personal journey includes 10-day silent retreats, 40-day fasts, plant medicine initiations, and years leading sacred ceremonies through kirtan, cacao, and devotion. His understanding of healing is not just learned — it is lived.

Alongside accredited ThetaHealing® trainings, he has also created and taught original transformational programs around the world — always centred on presence, energetic clarity, and soul-rooted integrity.


If you’re looking for more than a method — if you’re ready for real transformation from a master who walks his talk — you’re in the right place.
