Dr. Queenie Lo, Ph.D., C.Psych.

Psychologist

Dr. Lo has a particular interest in personality functioning and the betterment of psychological well-being. She works with individuals across life stages – children, adolescents, and adults. She believes the best outcomes are achieved through working collaboratively with her clients. With children, working with the parents and families is often an integral part of the therapeutic process. She recognizes the undeniable uniqueness and complexity of the emotional and relational experiences for each individual, whether a very young child or an adult, which manifest as a variety of subjective satisfaction/distress, thought, and behaviours. This shapes her belief in the necessity of an individualized and comprehensive understanding of a person’s needs in order to foster growth and positive changes.

Dr. Lo primarily grounds her work in the richness of the Psychodynamic perspective. To fully appreciate the complexity of an individual’s mind and experiences, her work is inclusively informed by other modalities, such as Humanistic, Family Systems, Emotion Focused and Cognitive-Behavioural therapeutic approaches. Her philosophy of practice is a continuous integration of theoretical curiosity and empirical research, with the direct collaboration of clients to give rise to a meaningful and useful therapeutic process and outcome.

Dr. Lo has been in full-time private practice since 2012. Previously, she had worked in a variety of settings including the hospital, school boards, and community based out-patient programs. She has been a part of many inter-disciplinary teams (e.g., Speech-Language Pathology, Audiology, Education, Psychiatry, Social Work) and provided clinical supervision to allied mental health professionals. Currently she provides in-depth clinical training and mentorships for doctoral-level clinical psychology students and early career psychologists, as an additional way to contribute to the advancement in the field of psychology and mental health.

As a registered psychologist, Dr. Lo completed seven years of graduate and post-doctoral education and training in school and clinical psychology. She graduated with her doctoral degree at OISE/University of Toronto in 2007 (APA and CPA accredited). She pursued a post-doctoral fellowship at Sickkids Community Mental Health, where she furthered her competency working with adults. She has been a registered member of the College of Psychologists and Behaviour Analysts of Ontario (CPBAO) since 2009. She regularly engages in peer study groups and professional development to share best practices and maintain up-to-date knowledge in psychology.

She has a language proficiency in English and Cantonese.
