Therapist Appreciation Day began as a community submission by Blake Sherman, and Holiday Calendar established it as an observance in 2025. It shares its September 25 date with National Psychotherapy Day, a separate observance documented since 2012.
A study at Clark University
In July 1892, a small group of academics gathered in the study of G. Stanley Hall at Clark University and founded the American Psychological Association. Hall became its first president. At the start it was a scholarly society, not a clinical one. The idea that a psychologist might sit across from a paying patient came later.
Today that same body counts more than 172,000 members, the largest psychology organization in the country.
