Lydia Guthrie is a trainer, group facilitator and supervisor, working in criminal justice, mental health and social work settings. She spent ten years working for the Probation Service in a range of specialisms, including work with long term prisoners, and groupwork with men who have committed sexual abuse and domestic abuse. She worked as a supervisor and team manager, and also developed and delivered programmes for victims and survivors of abuse.

From 2008 to 2012, she was contracted - with Clark Baim - as co-lead national trainer for the UK's community-based sexual offending treatment programmes, run by the Probation Service for England and Wales. Before qualifying as a social worker, she gained an undergraduate degree (PPE) and an MSc in Social Work from Oxford University, and worked in the voluntary sector with adults with learning disabilities, adults with physical disabilities, and with teenagers in the "looked after" system.

Lydia is passionate about attachment theory, reflective supervision, mindfulness and self-compassion. As a believer in life-long learning, she has studied extensively in the Dynamic Maturational Model of Attachment and Adaptation.
