Antistixi’s therapeutic and training agenda involves constant research focused not only on psychopathology, but also on the question of functional relationships, particularly the romantic, family and professional relationships. Simultaneously, original scientific articles on Existential Systemic thought are written to be published and presented in international scientific conventions.
Working with people, we experience the deep anguish about their personal journey, the reality of human relationships and systems. This awareness leads to the pioneering theorization of Existential Systems Theory.
The honesty and commitment to change and evolution that characterize our clients inspire us. At the same time, they make us deeply optimistic about the future of psychotherapy and the greatness of human beings and interpersonal relationships, despite the imperfections and limitations of life.
Antistixis publications are the culmination of the metabolism of scientific knowledge combined with clinical experience. The books are written in a way that is easy to read for the general public and, at the same time, constitute important tools for mental health professionals.
