At Cassiobury Court, we provide recovery-focused substance misuse treatment within a safe, supportive environment that promotes safe, positive risk management and supports sustainable recovery. By combining clinical expertise with person-centred care, we then tailor treatment to individual needs, circumstances and recovery goals, working alongside every person from medically managed detox through to therapy and rehabilitation.
For some people, treatment starts with a medically managed detox to support withdrawal safely and as comfortably as possible. After this stage comes tailored therapeutic programmes designed around longer-term recovery aims.
We hold high professional standards at our CQC-registered rehab clinic. Many of our recovery support workers also bring lived experience of recovery, which offers a unique level of understanding, empathy and hope. Their insight helps inspire confidence and show that lasting recovery really is possible.
