    This book gathers together the experiences of leaders across sectors, organisations and client groups to help readers introduce, develop and maintain Psychologically Informed Environments (PIE) and Trauma Informed Care (TIC) within their workspaces.

    Featuring the voices of providers, commissioners, consultants, and trainers from the NHS, local authorities, and the voluntary sector, this unique text includes chapters on implementing PIE across a range of overlapping fields, including young people’s, homelessness, mental health, and women’s services. Each chapter describes the contributors’ experiences of which factors and processes enable or disable successful implementation of PIE/TIC; the unique challenges of leadership within this process; and how to understand the different dynamics at play in an organisation that determine effectiveness. With an emphasis on practical examples underpinned by theory, and recommendations drawn from the emergent themes, the book acts as an invitation for leaders to explore how they can influence the growth and evolving shape of PIE and Trauma Informed approaches across health and social care and support settings, and beyond.


    This book will be an  invaluable resource for aspiring and new, as well as experienced, leaders who are interested in implementing and enabling PIE and TIC in their organisations.

     "If you are leading or managing people in health and social care, then this is the book you should be reading. It invites you to place a magnifying glass on the relationships you cultivate and curate, and on the crucial role of relationships in delivering good quality health or social care services.  As organisations and their clients become more diverse, leaders need to ‘read the room’ and adapt their style to truly engage with their teams and get the best from their staff".

    Charlotte Sweeney OBE, Co-author of Inclusive Leadership and CEO of Charlotte Sweeney Associates     


    "This new book is important for senior managers and commissioners grappling with the challenge of making services truly meet the needs of their clients. The authors bring a wide range of professional experience in the NHS, local authority and not-for-profit sectors, together with their wisdom and humanity, to describe how relational working from the top down is fundamental to putting the concept of being trauma or psychologically informed into practice”.

    Alex Bax Chief Executive at Pathway.


    ''This book provides a toolkit for anyone working in health, social care and support services  to improve how we lead, manage, commission and deliver our services and in so doing, create psychologically informed environments (PIE) and trauma informed care (TIC).  Recognising how working with people who are traumatised and marginalised impacts on practitioners and organisations is only the starting point of ongoing journeys that evidence positive impact and outcomes for people and those who work with them. Contributors provide key messages on how to develop PIE and TIC - for practitioners, managers, and leaders, in voluntary and statutory organisations and for partnerships across whole systems.''
