Sarah Hill

Sarah Hill is the Owner and Co-Director of Dialogix and a Director at Kantor Institute. For more than a decade she has specialised in the design and leadership of major whole-system cultural change interventions using Dialogue and Structural Dynamics and has become an internationally recognised expert in the training of coaches and leaders to become accomplished Dialogic Practitioners and Structural Dynamics Interventionists in their own right. Sarah coaches, trains and advises senior leadership teams and national boards worldwide as they develop new models for practice, behaviours and funding and has been described as a coach and leader who ‘walks the talk’ and is driven by ethical practice. She believes the potential to reform people’s experience stems from courageous personal action that comes through the understanding and practice of dialogue, structural dynamics and mindfulness. Developing others to lead powerful and productive conversations lies at the heart of all she does. She is focused on enabling people to release the power that is intrinsic to leadership, through the way in which they talk and think together within organisations.

“Through learning about how conversation works it is possible to move beyond dysfunctional situations and improve the quality of interaction, thereby offering more effective leadership.”

Sarah is pragmatic and compassionate in her support and challenge of others in their efforts to create decent and sustainable change. You will see evidence of this in the way her coaching and consulting embodies respect, honesty, integrity and a non-judgmental approach.

Sarah holds a PhD and has published articles on collaborative research, multi-stakeholder dialogue in prisons, working with ‘invisible realities’  and issues of integrity through the lens of Structural Dynamics.
