Siân Williams

sian williamsPrincipal Consultant of Thorsborne and Associates


Siân has spent her career working with young people, spending nine years as a head of department and head of year in inner London secondary schools before joining a London local authority for seven years. Siân has led on many authority-wide initiatives, including restorative approaches, anti-bullying, safer schools, social and emotional learning, learning mentors and learning support units. In addition to her role as Principal Consultant with Thorsborne and Associates, she works as an independent educational adviser and trainer in conjunction with her role as Head of Support for the National Youth Orchestra.

Experience and Expertise

Siân trained as a restorative justice community conference facilitator in 2004, and as a workplace restorative conference facilitator in 2006.  Since her training, she has facilitated numerous conferences involving a variety of young people, adults, parents/carers and members of the community – most at the ‘pointy end’ of the severity scale – and was often called on by head teachers and senior local authority staff to work through incidents of conflict between staff. Sian was accredited as a Restorative Practitioner by the Restorative Justice Council (RJC) in September, 2011. She is also an experienced mediator and regularly volunteers for her local neighbourhood mediation organisation.

Siân has great strengths in relation to strategic planning at both school and local authority level, particularly in the areas of restorative practice, anti-bullying strategy – most recently sexual bullying – and social and emotional learning. She thrives on working with a variety of partners.  Senior school staff find her warm, approachable and honest style of critical friendship invaluable, and she has helped to shape change in a wide range of schools, and clusters of schools, across England.  She is also known for her well-honed project management skills including a well-founded reputation for delivering high quality outcomes within (sometimes very tight!) deadlines.

As a pioneer within the field of leading on the introduction, implementation and embedding of restorative practice for young people within local authority settings, Siân has been called on to present at national and international conferences (UK, Australia, New Zealand, Canada) where people have commented on her clarity, knowledge and enthusiasm. She has also co-written a book about schools’ experience of restorative practice; a staff resource guide for sexual bullying and chapters in forthcoming books about sexual bullying.  As a teacher, she loves any opportunity to train people; in relation to restorative practice, Siân is experienced in delivering both two- and three-day training as well as shorter awareness-raising sessions.


Siân has a BA (Hons) in Music, a Secondary PGCE and a MA in School Effectiveness and School Improvement.  She is a member of the Restorative Justice Council, an accredited Restorative Practitioner (RJC), Restorative Practices International and the Tomkins Institute.
