The Cassel Hospital


The Cassel Hospital is an NHS Tier 4 specialist personality disorder service and is part of West London Mental Health Trust.
We deliver combined psychosocial and psychoanalytic treatment through Inpatient and Outreach treatment programs. The Inpatient service provides residential treatment at the Cassel Hospital in Richmond, Surrey. The Outreach service provides community-based treatment and may follow on from the Inpatient program or may be accessed directly, depending on need and individual circumstances.
The purpose of our service is to help people reduce self-harm, suicidal and other self-destructive behaviours, build and foster healthy social and family relationships and to integrate back into the community, with a reduced reliance on local mental health services.
Our unique treatment approach is built on decades of experience and a strong evidence-base. Our dedicated Research Unit continually audits treatment outcomes and results show that our treatment is effective with even very difficult cases.
