Cedar Create | Eco-Systemic Psychotherapy Workshops
Join Professor Emily Zobel Marshall and Imelda McCarthy for an ecosystemic psychotherapy workshop, facilitated by Professor Hannah Sherbersky and Roger Duncan on 23rd April 2026.
Emily Zobel Marshall will lead a session on Contested Landscapes: Decolonising the Outdoors in Poetry and Motion. It will explore and ask what it means to try and decolonise both the literary and physical landscapes of the UK and examine the vital role that walking groups for people of colour play in the lives of Black and brown hikers. Through poetry exercises it will ask participants to creatively respond to and consider the healing power of the natural world and our complex contemporary relationship with it.
Imelda McCarthy will then lead a session on Ecosystemic Epistemologies: Developing ways of seeing, thinking, and practicing beyond binaries and deconstructing separations while co-constructing connections and communities of love. There will then be an interview-style discussion between Imelda & the programme leads Hannah & Roger with Q&A afterwards.
This workshop is held online via Zoom on 23rd April 2026 between 09:30am and 16:30pm. A place on the workshop will cost £125 per person. You can book a place on this workshop by following this link
