About us Our team Pact Trustees Sarah Mann The latter part of Sarah Mann’s career in the Home Office and Ministry of Justice was spent in the National Offender Management Service working mainly with the probation service. She headed units responsible for the assessment and management of offenders (including intensive alternatives to custody and integrated offender management) and for the development and delivery of punitive and rehabilitative elements of community sentences. She was closely involved in the introduction of evidence-based practice across the probation service and led the development team that created the Offender Assessment System (OASys). Her career also included 18 months on secondment to the voluntary sector. She was a trustee of the Prisoners’ Families and Friends Service from 2012 until its merger with Pact in June 2014.
