Some truths lie beyond words; they live in the voice.


The voice is a doorway for parts of ourselves long silenced or constrained to find expression.
This immersive training explores the voice as a therapeutic and relational instrument, offering a direct way to work with emotion, trauma, and embodied expression beyond performance-based practice or cognitive therapy.
Improvisation & Polyphony
Circle singing and folk song traditions to cultivate presence, listening, and shared resonance.
Embodied Voice Work
Vocal practices engaging body, breath, and sound to access deep emotional truth.
Authentic Relating
Speaking from direct sensation and lived experience, beyond habit or performance.
Contemplative Silence
Inner listening practices supporting nervous system regulation and integration.
This is not a performance or technique class. Designed for depth practitioners who want to work with voice as a tool for healing and transformation, this training approaches the voice as an embodied, relational, and contemplative practice. No prior singing experience is required; matching pitch is enough.
Experiential Inquiry
Sustained embodied exploration through silence, sound, and song — moving deliberately between containment and expression.
Somatic Vocal Regulation
Work with the voice as an extension of the nervous system: releasing held emotions, accessing vitality, and restoring fluidity between body, feeling, and expression.
Relational Field Practice
Participate in carefully held group work where sounding, witnessing, and resonance create safety, trust, and depth within the collective field.
Expert Guidance
Receive attentive, precise guidance from Guillermo Rozenthuler and Dr Swan Dao, offering structured frameworks alongside sensitive, individualised support throughout the training.
• A deeper understanding of the voice as a therapeutic tool
• Fluency in vocal regulation under emotional activation
• A voice able to hold vulnerability, intensity, and silence
• Confidence to apply these insights in life and practice.

Guillermo Rozenthuler and Dr Swan Dao share a rigorous, relational approach to the voice, grounded in decades of international practice at the intersection of art, psychotherapy, and experiential learning.
Guillermo is a leading authority in vocal improvisation and pedagogy; Swan is an acclaimed psychotherapist and experience designer renowned for their pioneering experiential and expressive approaches to healing.
Together, they offer a rare training environment where the voice is approached with creativity, sensitivity, and depth.

A NATURE SANCTUARY NEAR LISBON
Set within the softly rolling hills of Sobral de Monte Agraço, our retreat centre unfolds across 16 hectares of quiet countryside, just 30 minutes north of Lisbon. The land includes a natural swimming pond, a wood-fired sauna, and a range of contemplative spaces woven into the landscape. The centre is dedicated to expressive, introspective, and collective practices that support cognitive, emotional, and spiritual development.
Our hosts cultivate a warm, family-like atmosphere where guests feel immediately at home. Meals are nutritious and lovingly prepared — plant-based, primarily organic, and made with local, seasonal ingredients. Tea and wholesome snacks are available throughout the day, ensuring you feel nourished and cared for at every moment of your stay.
