SHIRLEY PSYCHOLOGICAL SERVICES
About Shirley Psychological Services
Who We Are
You're not alone in this.
Shirley Psychological Services is a Calgary-based group of registered psychologists offering compassionate, evidence-based therapy for children and teens, adults, and families throughout Alberta. We provide both in-person sessions at our southeast Calgary office and virtual sessions for all Albertans.
Our team brings together over 65 years of combined clinical experience across diverse settings, from residential programs and crisis services to community mental health and private practice. What sets us apart isn't just our expertise; it's that many of us have walked similar paths as parents, partners, and people navigating life's messy transitions. We bring both professional training and lived experience to our work.
Four therapists,
one philosophy.
