Dr. Andrew Lumb

C. Psych.
Clinical and Health Psychologist

My therapeutic style is warm, genuine, and non-judgmental. I will work collaboratively with you to understand your concerns and identify what triggers and maintains your specific problem(s). Together, we will come up with a treatment plan that is in line with your needs and goals. Using evidence based treatment approaches, we will work together to build on your strengths and develop new skills to reduce distress and improve your quality of life.  

I am a registered Clinical and Health Psychologist with the College of Psychologists of Ontario. My therapeutic orientation is primarily grounded in cognitive-behavioural therapies [i.e., Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Dialectical Behaviour Therapy (DBT-informed)], and I integrate motivational interviewing and emotion-focused approaches.

Aside from working in private practice, I currently work part-time as a psychologist in the Substance Use and Concurrent Disorders Program at the Royal Ottawa Mental Health Centre (ROMHC). I am involved in the training and supervision of doctoral students in clinical psychology from the University of Ottawa and psychology residents at the ROMHC.
