Sarah Hill


Dr. Sarah Hill is Co-owner of Dialogix and is based in the UK. Her early career involved her working in a range of different sectors, which formed the basis for her work as a Dialogue Facilitator and Behavioural Dynamics Interventionist. She has lead behavioural interventions with individuals, teams and across whole organisations and communities located in the UK, USA, Latin America, Australia and Europe. The focus of this work is on tackling some of the toughest and most demanding behavioural challenges. Sarah also coaches CEOs and Senior Leaders from a range of different cultures and countries, as well as within large and small, corporate, public sector and not-for-profit organisations. She has led the design and development of training in this field that is accredited by the International Coaching Federation. Through her experience as a supervisor of coaches and practitioners she has been described as the “consultant’s consultant“.

Sarah is 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. Developing others to lead powerful and productive conversations lies at the heart of all she does. Her focus is on enabling people to release the power that is intrinsic to leadership, through the ways in which they talk and think together within organisations. 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-judgemental approach. 

Sarah is author of “Where Did You Learn To Behave Like That? A Coaching Guide For Working With Leaders“. Working globally, she is an internationally recognised expert in childhood story work with leaders providing a way for them to do deeper work on the Self. Her ambition as a thought leader is to help leaders recognise that their unresolved childhood stories not only impact themselves but the teams and whole systems they lead as well.

Sarah holds a PhD and has published articles on collaborative research, working with invisible realities and issues of integrity through the lens of Structural Dynamics. Her forthcoming co-authored book, The Tao of Dialogue, will be published later in 2018.

Rachel Horton-Smyth


Rachel’s background as an award-winning communications specialist has seen her work in a number of high profile roles both in the UK and internationally – often in environments where effective communication is one of the greatest challenges. She has spent more than a decade working to improve communications structures and practice in large organisations, including acting in an advisory capacity to the very highest levels of British Government.

Whilst Head of Communications at a British police force, Rachel was introduced to the Dialogix Model and found instant application for it in her work. Applying the theory she found it was possible to break down deeply engrained dysfunctional communication patterns, creating an environment in which it was truly possible to talk and think together.

Rachel has subsequently become an accredited interventionist, going on to lead bespoke pieces of work designed to bring about sustainable, transformational behavioural change in teams and across systems. She has worked with senior leaders, organisational development professionals and coaches across Europe, Australia, Latin America and the US, helping them to develop their understanding and application of Dialogue and Structural Dynamics in a wide variety of different environments.

Rachel holds a degree in Law and Politics from the University of Nottingham and is qualified through the National Council of Training for Journalists. She has completed advanced communications training at the British Defence Media Operations Centre and is a graduate of the National Policing Improvement Agency’s Senior Leadership Programme.

Donata Caira


Donata is an Organisational Development Consultant with over 20 years experience of working in cross sector businesses, from working with local charities to global corporations such as Rolls-Royce. This gives her an incredible depth and breadth of understanding of how people can work together to bring about changes they desire. Donata has a clear belief that developing and nurturing supportive yet robust networks of relationships within the organisation sustain personal, team and organisational change. She has gained a reputation for being able to open up spaces that are safe, supportive and challenging – allowing clients to explore their issues, dilemmas and struggles. She is recognised as a skilful listener, clear thinker and is able to get to the core of issues and dilemmas helping leaders face whatever it is they need to do to be successful and then support them through the challenging conversations that are often being avoided.

“I relate to my clients as whole persons, engaging in the richness of their lives and not simply compartmentalise their business existence, likewise I bring my own passions and curiosities, this normally means having illuminating, inquiring conversations that lead to changes in outlook and behaviour.”

Over the past 6 years the combination of Dialogue and Structural Dynamics has become central to Donata’s consulting practice and has made a significant difference to how she engages with clients as they discover together what is ‘really’ needed to make change happen.

Donata holds an MSc in Organisation Consulting and is currently immersed in her own Structural Dynamics development.
