Complexity and Consciousness: An Embodied Ketamine Assisted Psychotherapy Journey

December 5-8, 2026 | Tahquitz Pines in Idylwilld, California

Complexity and Consciousness: An Embodied, Experiential Ketamine-Assisted Retreat

Join Dr. Carrie Griffin, Mahshid Hager, and Joshua Sylvae for a four-day immersive retreat exploring the intersection of ketamine, consciousness, and embodied experience. Drawing on our combined experience in somatic work, psychotherapy, ketamine-assisted therapy, and facilitating transformative experiences, we’ll create space for curiosity, exploration, connection, and integration.

Through supported ketamine journeys, along with preparation, reflection, and integration, you’ll be invited to explore your experience at your own pace, with compassionate support for whatever emerges.

Where You'll Stay

Tahquitz Pines sits among tall pines in Idyllwild, a mile up in the San Jacinto Mountains. Quiet cabins, fresh mountain air, and space to slow down. Between sessions, there’s room to walk the grounds, sit by the fire, or just rest.
