Approach

In our work together, we’ll build practical skills and strategies to help you face and move through hardship. In a supportive, nonjudgmental space, we’ll focus on reducing distressing symptoms and patterns, strengthening emotional regulation, and improving coping in day-to-day life. When relevant, we’ll also address relationships, including social and family communication.

I take a collaborative, evidence-based approach—grounded in compassion and hope—to help reduce stress and support lasting well-being. Together, we’ll develop a clear understanding of what’s bringing you in, identify meaningful goals, and create a personalized treatment plan that fits your needs. My training includes a range of modalities, including ACT, DBT, EMDR, Prolonged Exposure (PE), CBT (including Trauma-Focused CBT), Brainspotting, Solution-Focused Therapy, and Somatic approaches (including Somatic Experiencing). My work is oriented toward symptom relief, empowerment, and helping you feel more in control of your life.

I also offer comprehensive, collaborative assessments for mental health and academic concerns. The process may include a clinical interview, standardized evidence-based measures, consultation with relevant parties when appropriate, and diagnostic clarification. The goal is to provide clear recommendations and a tailored plan to support you or your child (ages seven and up).

Education and Experience

Before pursuing psychology, I trained at Randolph College for the Performing Arts and worked as an Assistant Director in Toronto’s film industry. A growing interest in what shapes human motivation led me to complete an Honours B.A. in Psychology at Trent University, with a focus on human development and attachment. I then earned a Master’s in Drama Therapy at Concordia University, completing internships with the Montreal Association for the Blind and the Jewish General Hospital. During this time, I also contributed to research examining attachment relationships between single mothers and their children experiencing behavioural and emotional challenges.

Following my master’s degree, I worked at the Phoenix Centre supporting children, adolescents, and families in a range of settings—as a child and family therapist, within a day-treatment classroom, in local high schools, and as a youth engagement facilitator with the Centre of Excellence for Child and Youth Mental Health.

I later completed a Ph.D. in Counselling Psychology at McGill University, with clinical placements at Concordia University, Agence Ometz, and the Phoenix Centre. My training emphasized culturally responsive, gender-affirming care. My dissertation explored youth engagement in mental health by partnering with young people to refine a self-compassion program aimed at improving well-being.

Since 2014, I have specialized in working with veterans, active military members, and first responders.
