“As creator of the Core Language® Approach, I’ve spent the last 20 years observing how language and trauma intersect—how patients’ presenting symptoms, specifically the language they use, can lead us to the root of the issue, often to a trauma in the family history or in early childhood. Uncovering our core language can free us from reliving traumas that don’t belong to us.”
