Job overview
The Forensic Liaison & Diversion (L&D) Service is looking for a Senior Mental Health Practitioner to join our service. This is an exciting and unique opportunity to join the Forensic Liaison and Diversion Team in South-West London & St George’s Mental Health Trust (SWLSTG).
The Forensic Liaison and Diversion (L&D) services aim to provide early intervention for vulnerable people of all ages as they come to the attention of the criminal justice system. L&D services provide a prompt response to concerns raised by the police, probation service, youth offending teams or court staff, and provide critical information to decision-makers in the justice system, in real time, when it comes to charging and sentencing these vulnerable people. L&D also acts as a point of referral and assertive follow up for these services users, to ensure they can access, and are supported to attend, treatment and rehabilitation appointments.
In this way, L&D services are expected to help reduce reoffending, reduce unnecessary use of police and court time, ensure that health matters are dealt with by healthcare professionals, and reduce health inequalities for some of the most vulnerable in society.
