Clean Language
Developed in the 1980s by David Grove, a New Zealand psychologist of Māori heritage, Clean Language is a unique approach to questioning that enables people to explore their own words, metaphors and experiences without imposed interpretation.
Originally from Aotearoa New Zealand, Sarah de Castro has spent over a decade studying and practising Clean Language, mentored and sponsored by Jennifer de Gandt, a close collaborator of David Grove. A member of the Clean Language France Collège des Experts, Sarah combines her experience as a practitioner, trainer and supervisor with in-depth academic research at EHESS/ENS/CNRS, exploring Clean Language's Indigenous connections and its contribution to client-led coaching and psychotherapy.

“Meaning does not converge toward singular explanation, diagnostic categorisation, or authoritative interpretation.”
