​
I obtained a Bachelor of Arts (B.A.) degree in Honours Psychology from Concordia University (Montreal, Quebec) in 2005, and a Master's of Arts (M.A.) degree in Clinical Developmental Psychology from York University (Toronto, Ontario) in 2007. In 2012, I completed a Canadian Psychological Association (CPA) accredited Doctor of Philosophy (Ph.D.) degree in Clinical Developmental Psychology and a Health Psychology Graduate Diploma at York University.​ My graduate research was funded by provincial and federal scholarships and I've co-authored several publications in the areas of pediatric pain, parent-child relationships (e.g. caregiver emotional availability) and infant emotion regulation.
​
​I've worked with children and families from various cultural backgrounds, who were experiencing a wide range of clinical, learning and developmental difficulties, across various age groups (infancy to adulthood). I've worked in a variety of settings including children’s mental health centers (e.g. Thistletown Regional Centre, Reach Out Centre for Kids and Mothercraft - Breaking the Cycle), university clinics (e.g. York University Psychology Clinic) and pediatric hospitals (e.g. Holland Bloorview Kids Rehabilitation Hospital) in Toronto, Ontario. In addition, I completed a CPA accredited pre-doctoral internship in Clinical Child Psychology at the Children’s Hospital of Eastern Ontario (CHEO) in Ottawa, Ontario, where I gained additional experience in the areas of Pediatric Health Psychology, Inpatient Mental Health, Crisis Assessment, Autism Assessment, Neuropsychology, Family Therapy, Individual Therapy and Program Evaluation.​
​
My approach to case conceptualization and intervention is based on a Developmental Psychopathology framework. I believe that a child is influenced by a dynamic interplay of biological, psychological and social influences. For example, I consider the roles of child factors, family and school environments, peer relationships, and social-cultural contexts in the etiology of a child’s difficulties. Given that children and youth thrive in the context of healthy and supportive relationships, I place a lot of importance on strengthening family and social connections in therapy.
I believe in the scientist-practitioner model, namely that clinical practice should be informed by research. My main theoretical orientation is Integrative meaning that I combine different evidence-based (empirically supported) therapeutic tools and approaches to fit the needs of my clients. Although I mainly use Cognitive Behavioural Therapy (CBT), I also draw from elements of Motivational Interviewing, Brief-Solution Focused Therapy, Family Systems and Attachment Theory. Despite the chosen course of treatment, I strongly believe that the therapeutic alliance between a client and therapist is of equal importance. As such, I aim to provide a supportive environment in which my clients feel safe to disclose personal information and build trust in the therapeutic relationship.
​
I'm registered with the College of Psychologist of Ontario (CPO) and I maintain memberships in several local, provincial and national professional associations.
