The study of the trauma of birth in psychology began in 1924, with the publication of the work of Otto Rank, a disciple of Freud. It stayed alive in psychoanalysis until neuroscience and epigenetics revealed the importance of the mother-baby connection through the study of attachment and infant mental health. The field of prenatal and perinatal psychology has further developed and differentiated into a somatic practice. The baby's experience starting preconception is necessarily a somatic, body-based, implicit memory exploration. Best practices include this understanding and therapists who work with our earliest experiences are necessarily somatic, body-based therapists. The science that supports prenatal and perinatal somatics includes polyvagal theory, implicit memory, the impact of stress and other maternal experiences on the baby inutero, family dynamics, and transgenerational and intergenerational trauma. We also include a study of embryology, epigenetics, Biodynamic craniosacral therapy, and polarity therapy.

This Network is a list of practitioners who have been trained by Ray Castellino and other teachers who understand the impact of earliest trauma on the nervous system. We have divided the practitioner list into five categories:

• Adults with earliest trauma (Preconception through 18 months of life)
• Mothers and Babies, including manual therapists
• Family Dynamics
• Womb Surround and Birth Process Practitioners
• Graduates from Integrated Prenatal and Perinatal Dynamics who can work with Birth Trauma

Practitioners are listed by name, with their location under the grouping that is their specialty.
