Windy Dryden is Professor of Psychotherapeutic Studies, Goldsmiths College, University of London. He is a Fellow of the British Psychological Society and of the British Association for Counselling and Psychotherapy. He began his training in REBT in 1977 and became the first Briton to be accredited as an REBT therapist by the Albert Ellis Institute. In 1981, Windy spent a six month sabbatical at the Center for Cognitive Therapy, University of Pennsylvania, one of the first British psychologists to do an extended training in cognitive therapy. He is a Fellow of the Albert Ellis Institute and a Founding Fellow of the Academy of Cognitive Therapy.

While his primary therapeutic orientation is REBT, Windy has been very much influenced by his cognitive therapy colleagues and by the working alliance theory of Ed Bordin. His research interests are in the historical and theoretical roots of REBT (with Arthur Still) and the phenomenology of hurt, the study of which is informed by REBT theory.

Windy is perhaps best known for his voluminous writings in REBT/CBT and the wider field of counselling and psychotherapy. To date he has authored or edited over 160 books, making him probably the most prolific book writer and editor currently alive in the field today. He has also edited 17 series of books including the best selling "Counselling in Action" series.

Windy was the founding editor of the British Journal of Cognitive Psychotherapy in 1982 which later merged with the Cognitive Behaviorist to become the Journal of Cognitive Psychotherapy: An International Quarterly. Windy was co-founding editor of this journal with E. Thomas Dowd. In 2003, Windy became the editor of the Journal of Rational-Emotive and Cognitive-Behaviour Therapy.
