Please feel free to email me at [email protected]. I will return your message within 2-3 business days. Therapy can be arranged online or in-person, based on your preference.   

I am registered as a clinical psychologist and neuropsychologist for adults and seniors.  I completed my PhD at Queen's University in 2004. I have worked in Kingston, Toronto, Halifax, Kitchener-Waterloo and Guelph. My clinical interests include anxiety and depressive disorders, geriatrics, dementia, caregivers, chronic pain, insomnia, stroke, and university student mental health.

I enjoy having a wide scope of practice, ranging from clinical assessment to individual therapy to teaching.  I use a collaborative, goal-oriented approach with my clients, which integrates cognitive-behavioral therapy (CBT) with person-centered, interpersonal therapy, mindfulness, and motivational interviewing. For over 12 years, I have taught at the University of Waterloo. My courses include Theories of Individual Counseling and Resilience and Social Support.
