Clients present to therapy for a variety of reasons. I provide a safe, non-judgemental space that meets where the client is at, and gently explores what's happening in their life. Together we can work towards goals that are alligned with their hopes, aspirations, desires or needs; to improve connection with the self, interpersonal relationships and the interplay with their surrounding social world.

I'm a trauma-informed counsellor with extensive experience in DBT.
Many people come to counselling feeling stuck in survival mode. They are overwhelmed, constantly overthinking, emotionally reactive, or caught in the same relationship patterns they promised themselves they would not repeat. I work with people who are tired of analysing everything and still feeling the same. In our work together, we slow things down so you can understand what is driving your reactions, regulate your emotions, and respond differently with more clarity, control, and self-trust.

Dialectical Behaviour (DBT) Therapists
Who is DBT for?
Dialectical Behaviour Therapy (DBT) is designed for people who experience extreme emotional suffering because they lack the skills of emotion regulation and distress tolerance. The basic affliction can underlie a wide range of conditions, from borderline and other personality disorders to PTSD and treatment-resistant anxiety and depression. The therapy is helpful to those whose emotional reactivity is so intense it is disruptive to everyday functioning and leads to frequent crises.

Why do people need DBT?
The ability to regulate emotions is a core psychological skill that enables people to function in life and pay attention to the world outside themselves; it is consistently associated with well-being. DBT is designed to help people learn how to manage and regulate their emotions. Originally developed to treat people with borderline personality disorder whose extreme emotional suffering led to self-harming behaviour and suicide attempts, the therapy is now applied to other conditions involving emotion dysregulation, particularly when other treatments have failed.

What happens in DBT?
Individuals meet weekly with their therapist to discuss their experiences relating to moods, behaviour, and skills. Using checklists they maintain, they review emotional experiences and positive practices they engage in. The diaries help individuals discern what led up to a specific problem encountered, this is followed by discussion of the consequences of their actions. In addition, individuals may meet in class-like small groups to learn skills such as mindfulness, emotion regulation and distress tolerance.

How long does DBT last?
Because it is intended to establish long-lasting behavioural change among those with persistent problems, DBT is designed to last six months to a year. DBT includes both weekly sessions of individual therapy and weekly skills-training sessions conducted in small groups. Studies of DBT have documented improvement within a year of treatment, particularly in controlling self-harmful behaviour; nevertheless, individuals may require therapy for several years.
