Dr. Archibald has worked as a registered psychologist for over 30 years in hospital, outpatient mental health clinic and private practice settings primarily with adults experiencing distress related to depression, anxiety, trauma/PTSD, pain, chronic illness, cancer, MS, ADHD, grief, phase of life, relationships and workplace.

She is client-centred and collaborative in her approach, applying a biopsychosocial model with attention to the contribution of health/wellness, demographics (such has culture, race, SES, gender, age) and the role of trauma to understand a person's life context and how they think/understand themselves and others in relation to what has happened in life and how they have coped. She takes a phased approach to processing trauma. Therapeutic modalities include EMDR, parts work (SDT, IFS), MBSR, Mindfulness-Based CBT, CBT and ERP. She is an EMDR certified therapist (EMDRIA).

She did her residency at the Foothills Medical Centre in Calgary, Alberta, working with Psychiatric Adult Services, the Dual Diagnoses Addiction Centre, and Psychosocial Resources (Oncology) at the Tom Baker Cancer Centre.

She developed a clinical specialization in Multiple Sclerosis beginning with her graduate research at the Dalhousie MS Research Unit. She later worked with the University of Calgary MS Clinic, OPTIMUS and Research Program in the Faculty of Medicine Department of Clinical Neurosciences for more than a decade.
