Womb Surround Process Workshops

Zephyr, CPBT, RCST  , PE



In the tradition of Ray Castellino, Zephyr facilitates Womb Surround Process Workshops. This unique modality developed by Dr. Castellino engenders a high level of trust and choice among participants, laying the foundation for deep personal transformation nurtured by the health and safety of a resonant field.

All individuals with a sincere desire to transform any kind of limitation or pain in their life are welcome to participate. It is essential that participants have established support to return to after the workshop to aid with integration.


Zephyr is a graduate of Ray Castellino’s Prenatal and Birth Therapy Foundation Training, a graduate of Anna and John Chitty’s Biodynamic Craniosacral Therapy Training, and has spent over 700 hours supporting infants receiving medical care in a neonatal intensive care unit.


The arc of Zephyr's journey has been graced by the extraordinary gifts of Douglas Daher, Martin Weiner, Marion Woodman, Victoria Sloan, Ray Castellino, and Harvey Ruderian. Over the past twenty-five years, Zephyr has studied under Raymond Castellino, Mary Jackson, Tara Blasco, John Chitty, Anna Chitty, Mary Louise Muller, Debra Bochinski, Christopher Muller, Hugh Milne, Scott Zamurut, Dr. Susie Ludington, Marion Woodman, Michael Meade, and Robert Bly. The breadth of Zephyr’s perspective manifests in the wonder and gratitude they feel for the beauty of each soul met in this profound work.

Zephyr also holds bachelor’s and master’s degrees in civil engineering and construction management from Stanford University. They have lived five years in Africa – Libya, Ghana, and Tanzania – and worked thirty-five years in construction, public works, development, and relief work. Zephyr has written a novel, The Advocacy,  under the nom de plume, Melissa Fischer.

Workshop Format

This workshop is conducted in person. There may be four to seven participants in a workshop. The duration of the workshop is a function of the number of participants, with the longest duration being five days for seven participants. Each person will have a turn and, the following day, a debrief. Every participant brings the spirit of mutual cooperation and support to the group, and forms part of the surround for the turn person.

Womb Surround Process Workshops are grounded in the prenatal and perinatal (PPN) principles formulated and refined by Ray Castellino over decades of working in this form. The principles will be shared at the outset of the workshop, as they provide the fundamental container for the work.

This workshop is experiential and easily accessible to laypersons with no knowledge of the PPN field. Every person has implicit somatic memory of their own birth, which inherently serves as a personal reference and guide.

This workshop is not constellation work. Although participants may inhabit the energetics of family members of the turn person, when this happens, it happens organically and is not directed by the facilitator. Participants are never acting a role. All interactions are authentic expressions of each participant’s present experience.

This workshop is not regressive. There is no attempt to place the turn person into a prenatal or infantile state to re-experience their past. Such an approach has been shown to put the individual at risk of being re-traumatized.

This workshop supports the individual to fulfill an intention that serves their present life. In the course of exploring the intention and what may be blocking its fulfillment, an early imprint may arise. The workshop provides a strong, safe container within which the turn person may engage the imprint. Such engagement can transform energy previously locked within the imprint into a depth of resource that affords choice. The turn person gains freedom to recognize multiple options and to exercise discernment as to wh
ich option best serves their intention in the present moment. In addition to appreciating the implications of the turn person’s work for their own lives, participants in the surround learn to form “I” statements and provide accurate reflection. Differentiation and role clarification are also aspects of the work.


Persons who find their experience to be outside of categories, persons of duality or multiplicity - concurrent and nonconcurrent, as well as persons of all genders, expressions of gender, sexual orientations, races, ethnicities, ages, abilities, and spiritual perspectives are welcome. Drugs create energetic patterns that distort the authentic self, and, accordingly, have no place within the context of the workshop. Post-workshop integration is a key element in sustaining the deep transformation that occurs during the workshop. Applicants must identify the resources that will support their post-workshop integration.
