I am passionate about supporting adults who struggle with ADHD, substance use disorders and other addiction, anger and personality disorders (such as Borderline Personality Disorder).
Many of us have become masters in pretending that things are fine, when in reality our lives seem to be falling apart. Inside we feel like we’re drowning: overwhelmed by emotion, lost, & hopeless as we try to carry the burden of unresolved trauma, pain, & life’s curveballs hurled our way. Pushing aside these problems to get through each day to manage life’s responsibilities, we find ourselves numb, depressed, anxious, self-medicating, isolating, angry, & struggling with relationships. Together, we can work towards confronting unhealthy behaviours, understanding emotions, & healing from our past to create transformational change.

I specialize in Mood Disorders, Personality Disorders and Addiction
I am a Registered Psychotherapist and Registered Counselling Supervisor. My practice is guided by extensive experience working with people coming from various socioeconomic backgrounds as well as many years of serving the most vulnerable communities in Vancouver’s DTES. While my approach is integrative of modern theories and techniques, it heavily relies on Psychodynamic theories and practice. Psychodynamic Psychotherapy is a highly individualized treatment whose goal is not only to alleviate the most obvious symptom. It relies on the fact that our personalities are uniquely shaped by several developmental stages.

My approach to therapy is rooted in curiosity, compassion, and a belief in your capacity for change. I strive to create a space where you feel understood and supported as we work collaboratively toward meaningful growth. I support adults navigating the lasting impacts of trauma and the ways these experiences can influence emotions, relationships, self-perception, and behaviour. I view many struggles not as flaws, but as protective responses that were once helpful. Together, we explore these patterns with curiosity, not only to understand where they come from, but to process and integrate insights in ways that support lasting change.

What are the common treatment options for personality disorders?
Personality disorders are typically treated with psychotherapy, sometimes in conjunction with medication. Therapy can help people with personality disorders develop skills to tolerate difficult emotions, navigate interpersonal relationships, and solidify their sense of self. Medications can treat symptoms that co-occur with the disorder, such as depression, anger, aggression, and impulsivity.
When to seek treatment for personality disorders?
Even though treatment for personality disorders can be an uphill battle, it’s best to seek help if you suspect that you or a loved one is struggling with one, because personality disorders can create substantial problems in life. Symptoms depend on the specific disorder, but overall signs of personality disorders include consistent difficulty maintaining close relationships, dramatic variations in self-esteem, and an unstable sense of identity.
How long does therapy take for personality disorders?
The timeline for treating personality disorders isn’t as clear-cut as it is for other disorders. Change can be difficult, taking from around one year to five, 10, or more. The key is finding a therapist who has extensive experience treating the relevant disorder. For example, a psychologist who specialises in narcissistic personality disorder has specific communication strategies that allow them to sustain the relationship and be more effective with narcissistic patients.
Can therapy help people with personality disorders?
Research suggests that for those who are motivated to address concerns or interpersonal conflict related to a personality disorder, therapy is far more effective than no treatment, and that most people in therapy see improvements. However, since personality disorders involve entrenched elements of identity, they are less responsive to treatment than are other mental health conditions. Finding an expert who has extensive experience working with a given personality disorder is one factor that increases the likelihood of successful treatment.
