InnerMost Mixer with Diana Fosha, PhD

Inside Our First InnerMost Mixer with Diana Fosha, PhD

On November 20, 2025, InnerMost welcomed clinicians from across New York City for the inaugural InnerMost Mixer—a new monthly gathering designed to bring together therapists, psychiatrists, researchers, and medical professionals shaping the future of mental health care.

Held at our center in Manhattan, the evening brought warmth, curiosity, and a shared sense of purpose: building a clinical community grounded in authenticity, compassion, and rigorous science.

A Space for Connection in a Transforming Field

At InnerMost, we believe that healing doesn’t happen in isolation. The same is true for the evolution of our field. With psychedelic-assisted therapy emerging as one of the most promising areas of modern mental health, clinicians are hungry for trustworthy, grounded spaces to learn, collaborate, and grow together.

The InnerMost Mixer was created to meet that need. Each month, we convene an intimate group of professionals—some deeply trained in psychedelic modalities, others simply curious—to explore integrative mental health through open dialogue and genuine human connection.

A Conversation Between Two Pioneers

At the inaugural InnerMost Mixer, Dr. Casey Paleos and Dr. Diana Fosha explored the deep resonance between AEDP (Accelerated Experiential Dynamic Psychotherapy) and psychedelic-assisted therapy. Diana began by laying out the core pillars of AEDP:

  • A belief in the innate healing drive within every person
  • Undoing aloneness as the antidote to psychopathology
  • Experiential processing of emotion as the engine of transformation
  • Metatherapeutic processing as a rigorous method of integrating change

Diana emphasized that psychopathology is not a collection of defects but the natural result of being alone in overwhelming emotional experience. Healing occurs when that aloneness is undone through authentic, attuned relational connection.

Casey reflected on his own immersion training with Diana, noting how AEDP allows therapists to bring their humanness and woundedness into the room — not through disclosure, but through presence, attunement, and genuine relational authenticity. He highlighted the “potency of the relational field” that AEDP reliably creates, something he has only otherwise seen in psychedelic therapy.

Together, they articulated a shared thesis: Both AEDP and psychedelic medicine facilitate transformation by lowering defenses in the context of deep relational safety.

Psychedelics open access to emotion and memory; AEDP provides the attuned, emotionally-regulated, relational container necessary to process what emerges. This synergy is now being formally studied in the groundbreaking Mount Sinai randomized controlled trial comparing medicalized ketamine alone vs. ketamine + AEDP-informed psychotherapy.

The conversation positioned AEDP as:

  • A natural integration methodology for psychedelic experiences
  • A relational “technology” that mirrors the psychedelic mechanism of lowering defenses
  • A model that humanizes psychotherapy by inviting authentic presence from both therapist and patient

As Dr. Fosha shared, emotional healing begins not with technique, but with relationship:

“Psychopathology is the result of aloneness in the face of overwhelming experience. Therapy is the undoing of that aloneness.”

Dr. Paleos connected this to ketamine and psychedelic-assisted therapy, noting how relational safety and authenticity mirror the openings created during altered states of consciousness.

“The deepest healing happens when both therapist and patient bring their full humanness into the room,” he observed.

The talk concluded with reflections on community, connection, and the importance of clinicians having spaces like InnerMost to “undo aloneness” for themselves.

Why Events Like This Matter

As psychedelic therapies move toward broader clinical integration, the field is evolving rapidly—and carefully. The InnerMost Mixer is designed to be a home base for clinicians navigating that evolution with integrity.

Attendees left the event with:

  • New professional connections
  • Fresh clinical insights
  • A felt sense of belonging to a community
  • A renewed excitement for the future of therapy

Most importantly, they left feeling supported—not only in their work, but in their own humanness.
