Dr. Diana Mandeleew, Psy. D., C. Psych. (she/her)
Clinical Psychologist
I have over 20 years of assessment, treatment and clinical experience in a variety of settings, collaborating with psychiatrists and other medical and mental health professionals.
I approach each individual in a collaborative and kind way. I want to hear and understand you. Together, we will explore your strengths, identify areas of difficulties, understand what is happening, and figure out how you can move towards greater wellness.
