David Treleaven, PhD, is a writer, educator, and trauma professional specializing in the intersection of mindfulness and trauma. He is the author of Trauma-Sensitive Mindfulness (2018) and the Trauma-Sensitive Mindfulness Workbook (2025), both published by W. W. Norton. His first book has been translated into ten languages and is widely integrated into mindfulness teacher trainings and somatic programs worldwide.

David’s teaching focuses on helping practitioners create environments that are attuned to nervous system regulation, embodied awareness, and the nuanced dynamics of trauma. He works extensively with mindfulness teachers, yoga instructors, therapists, and somatic practitioners to bridge contemplative practice with trauma-informed care.

He has taught internationally at institutions such as the Oxford Mindfulness Centre, Brown University, UCLA, and Spirit Rock Meditation Center. Known for his clear, accessible approach, David translates complex trauma research into practical guidance for those seeking to cultivate safety, agency, and choice within movement- and mindfulness-based settings.
