“Courage starts with showing up and letting ourselves be seen.”
– Brené Brown, Daring Greatly, 2015Seeking help is not always easy, but it can be an incredibly rewarding and meaningful experience. As a psychologist at the Ottawa River Psychology Group, it is my privilege to accompany my clients through the incredible process of change that can be experienced through psychotherapy.I am a licensed clinical psychologist in Ontario and Québec. I am also a certified Perinatal Mental Health (PMH-C) clinician with Postpartum Support International.


I hold a bachelor degree in Psychology from the University of Ottawa and a doctoral degree in Psychology (Ph.D.-Psy.D.) from the Université du Québec à Montréal. My doctoral thesis focused on understanding how multicultural people identify to their cultural groups and negotiate their cultural differences as well as the repercussions of these processes on their psychological well-being. My doctoral thesis was awarded a doctoral fellowship by the Social Sciences and Humanities Research Council of Canada (SSHRC).

Training and Experience:

I have received clinical training in various settings, including a university clinic, a mental-health hospital and private clinics. My pre-doctoral internship was accomplished at the McGill University Health Centre in the Cognitive-Behavioural Service in which I completed my primary rotation in the bariatric surgery clinic, and secondary rotations in the mood disorders clinic and the anxiety disorders clinic. I have also received additional training from the Contextual Psychology Institute, the Training Institute for Child and Adolescent Eating Disorders, the Center for Research on Eating Disorders at Oxford and Postpartum Support International.

Over the course of my clinical training, I have been primarily trained in Cognitive-Behavioural Therapy (CBT) as well as in some third-wave approaches, including Acceptance-Commitment Therapy (ACT), Dialectical-Behavioural Therapy (DBT) and Radically Open Dialectical-Behavioural Therapy (RO-DBT). I have developed an interest and passion for compassionate intervention approaches, particularly for Compassion-Focused Therapy (CFT) and Mindful Self-Compassion (MSC).

I specialize in working with people struggling with Eating Disorders and Body-Image concerns using a Health at Every Size (HAES®) aligned approach, as well as with clients struggling with Perinatal Mental-Health difficulties. I also have experience conducting psychological assessments and psychotherapy with people suffering from Anxiety Disorders, Mood Disorders, Trauma-Related Disorders as well as low-self-esteem, relational and adjustment difficulties.


My therapeutic approach is collaborative, compassionate and evidence-based. Working with my clients, I use psychological interventions backed by scientific data to help them make meaningful changes to their lives, ease their suffering, and enhance their well-being.
