John Parr, MSc psychotherapy, developed the Emotional Assertiveness Model in 1995 whilst working as a psychotherapist. As he honed the model, developing techniques to facilitate application, he saw more and more clients benefit. This led to him writing a MSc Thesis on the subject. His model is now used in industry for team development, in schools to train children and teachers to communicate emotions, in families to improve family dynamics, in coaching and psychotherapy.
