Rachel Powell

My name is Sarvin Sabet, and I am currently a Psy.D. student in Clinical Neuropsychology at Adler University in Chicago. I am also a registered Psychological Associate in Ontario, Canada, with more than ten years of clinical experience. In Toronto, I serve as the Clinical Director of a psychological practice, where I provide psychological assessment and treatment to adults experiencing trauma-related concerns, mood and anxiety disorders, chronic pain, and complex psychological presentations. My academic and clinical interests focus on neuropsychology, neuroscience, and the relationship between brain functioning, psychological processes, and behavior. I am also pursuing graduate training in Clinical Psychopharmacology to further strengthen my integrative approach to mental health care and to deepen my understanding of how psychological, neurobiological, and pharmacological factors can be considered together in evidence-based clinical practice.
