About D.I.Diamond

Diamond — Originator of Costume Therapy™

Diamond (D. I. Diamond) is an independent researcher, artist, and facilitator developing Costume Therapy™ — an embodied, expressive arts methodology grounded in practice-based research and field-tested experimentation.

Costume Therapy emerged through years of underground work in performance, movement, ritual, and social experimentation. Developed outside academic and clinical institutions, the method was refined through direct application with adults seeking transformation, liberation, and reorganization of self beyond conventional therapeutic or coaching models.

Diamond’s work investigates how intentional physical transformation, adrenaline activation, role embodiment, and live social engagement can generate new self-states and encode future-oriented memory in real time. Their facilitation centers on witnessing, interpretation, and symbolic design, treating enacted experience as both meaningful metaphor and lived reality.

Rather than focusing on regulation or symptom management, Diamond’s approach works through precision, direction, and embodied engagement, allowing insight and emotional material to be metabolized during the experience itself. The method integrates influences from somatic psychology, drama therapy, embodied cognition, ritual studies, and social neuroscience while introducing original frameworks for trauma engagement, meaning-making, and identity reorganization through action.

Diamond is currently formalizing Costume Therapy through the establishment of the Costume Therapy Institute, marking a transition from underground practice to structured research, documentation, and interdisciplinary collaboration.

Originator of Costume Therapy™

Diamond (D. I. Diamond) is an independent researcher, artist, and facilitator developing Costume Therapy™ — an embodied, expressive arts methodology for adult identity exploration and experiential learning.

Their work is grounded in practice-based research, arts-based inquiry, and embodied research, developed through years of iterative, field-tested application rather than clinical or academic prescription.

Lived Research & Underground Origins

Costume Therapy emerged through Diamond’s long-term engagement with performance, movement, ritual, and social experimentation in underground and community-based contexts. Outside institutional settings, Diamond observed how intentional physical transformation and role enactment could produce immediate, measurable shifts in self-perception, social presence, and future orientation.

This work developed through direct facilitation, observation, and refinement — allowing the method to evolve in response to lived experience rather than theoretical abstraction.

Why It Was Developed Outside Academia

Costume Therapy was developed independently to preserve its experiential integrity. Existing academic and clinical structures often prioritize interpretation, diagnosis, or symbolic analysis, limiting opportunities for adults to explore identity through direct enactment.

Working outside these frameworks allowed the method to remain participant-led, consent-based, and responsive to real-time social dynamics.

Why It Is Being Formalized Now

As the method matured, the need for clarity, documentation, and ethical articulation became essential. Costume Therapy is now being formalized to support interdisciplinary dialogue, research collaboration, and responsible transmission — without compromising its non-clinical orientation.

Diamond is currently focused on refining the method’s theoretical foundation, scope of practice, and research potential while continuing applied facilitation.

Bio

Diamond is the originator of Costume Therapy™, an embodied expressive arts methodology that uses costume, role enactment, improvisation, and facilitated social interaction to support adult identity exploration and experiential learning. Developed through practice-based research and arts-based inquiry, the method integrates insights from embodied cognition, role theory, and social neuroscience while introducing original frameworks for live identity experimentation. Diamond works independently, offering workshops, coaching, and research-informed experiential formats while developing formal interdisciplinary collaborations.
