Founder Errol Campbell
Errol Campbell is the pioneer of ThetaHealing® in the UK — the first instructor in the country to earn both the Theta Master title and the prestigious Certificate of Science, and the founder of the UK’s very first certified ThetaHealing® school.
With more than 20 years as one of the modality’s most experienced instructors, he has guided thousands of students and helped shape the early foundations of ThetaHealing® in the UK — training many of the country’s first practitioners and supporting the growth of a strong, committed community.
His work has quietly supported public figures, founders, and individuals operating at the highest levels of influence. Across the UK, Europe, and Asia, he has guided thousands through breakthroughs in health, relationships, intuition, purpose, and performance — delivering results with depth, precision, and measurable impact.
Errol’s teaching is both spiritually deep and trauma-aware, grounded in a presence-based approach that creates safety and precision in every session. His background includes NLP Mastery, hypnotherapy, spiritual counselling, somatic integration, breathwork, and training across more than twenty advanced therapeutic and energetic modalities.
His depth is shaped by a global journey through the UK, Bali, Thailand, Malaysia, and Canada, where years of inner work, silence, retreat, and devotion refined his presence. His understanding of transformation is not theoretical — it is lived, embodied, and continually practised.
If you feel called to deepen your intuition, strengthen your confidence, and step into your next level of mastery, Theta Mastery offers a clear path forward. Explore the trainings — and when you're ready for guidance, a Focus Call will help you choose your most aligned step.
