I use evidence-based approaches like CBT, DBT, ACT, narrative therapy, mindfulness, and solution-focused strategies, all guided by a person-centered approach.
Sometimes children and teens get stuck in ways that feel overwhelming - big emotions, constant worry, challenges at school, or struggles with friends can make everyday life feel stressful. For neurodivergent children and teens, these challenges can sometimes look different or be misunderstood. You want your child or teen to feel accepted and supported while building confidence and skills that truly work for them.

Thornhill, ON L3T
I provide evidence-based, integrative psychotherapy tailored to each client’s need, using CBT, DBT, ACT, ST, MBSR, MBCT, and psychodynamic, existential, and Gestalt as appropriate.
Mental health is more than feeling “fine.” It is the ability to understand yourself, recognize emotional patterns shaping your life, and build a resilient inner world. I work with people seeking more than quick relief from anxiety, depression, adult ADHD, obsessive–compulsive tendencies, addictive behaviours, or perfectionistic and avoidant patterns, especially during relationship challenges, separation, or major life changes. My work supports evidence-based therapy, helping you slow down, sense emotions, and explore patterns shaping relationships and self, fostering clarity, grounding, and lasting steadiness as symptoms diminish.

Dialectical Behavior (DBT) Counsellors
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.
