I am a Clinical Psychologist (Master's & PhD from Queen's University). I offer treatment and assessment services for adults with diverse presenting needs. In individual therapy, specific areas of focus include trauma/PTSD, mood, relationship difficulties, and difficulties with managing emotions. My primary theoretical orientation is an integration/balance of CBT, mindfulness, DBT, EFT, and ACT. I also provide therapy to couples using emotionally focused therapy (EFT-C), which is based on attachment science. EFT-C fosters curiosity toward emotional experiences and connection, creating a secure bond between partners.
My interpersonal style is warm and open, integrating compassion, humour, and curiosity to co-create a new path forward to my client’s goals. Life is tough sometimes and if it were easy to problem-solve, then you'd have figured it out already. It's just not always that easy. But, you're not alone. Let's figure it out, together.
