The team were incredibly kind and informed, they took the time to go through all the options with me and helped us plan how to approach the matter.”

Meet Jose Pereira
José has spent most of his career inside leading residential treatment settings, progressing from Counsellor through Senior Counsellor, Head Therapist, and Clinical Manager. In those roles, he has led multidisciplinary clinical teams and worked with people over long periods, which means he understands what sustainable recovery actually looks like and how it gets built. He brings that long-view perspective into every session.
As an integrative therapist, José draws on Cognitive Behavioural Therapy (CBT), Cognitive Analytic Therapy (CAT), Motivational Interviewing, Relapse Prevention, Psychodynamic Therapy, Systemic approaches, and Gestalt Therapy. In practice, that means he works with the whole of you, and adapts his approach to what fits, rather than applying one method to every situation.
Alongside individual therapy, he runs group facilitation, psychoeducational workshops, clinical supervision, and training, and is fluent in English, Portuguese, French, and Spanish.
