Dynamic Psychotherapy Oriented by Dimensions International Society

PDD International Society

PDD (Dynamic Psychotherapy Oriented by Dimensions) is an integrative therapeutic methodology, created by Dr. Javier Castillo, strongly inspired by Jungian psychology and contemporary psychoanalysis, as well as introducing cognitive and behavioural dimensions.

PDD psychotherapists and coaches work with a scientific methodology that aims to help form a specific therapeutic framework to acquire the rigorousness and consistency necessary to be recognized as an evidence-based psychotherapeutic approach.

The PDD International Society has a permanent collaboration agreement with the Colegio Oficial de Psicología de la Comunidad Valenciana (Official College of Psychology of the Valencian Community).

Among the objectives of the society are the following:

Scientifically investigate the fundamentals of PDD and its further developments, helping to make its clinical application more pragmatic and consistent.

Accredit PDD psychotherapists and coaches who can develop their work as dimensional integrative therapists, certifying their rigorousness and professionalism.

Organize congresses, meetings, and seminars to raise awareness of PDD and its clinical applications.


Currently, our PDD association has a diverse and passionate international community. Among our members, you will find psychologists, psychotherapists, neurologists and coaching professionals who share a deep interest in this innovative methodology.

We are united by the desire to explore and apply PDD (Dynamic Psychotherapy Oriented by Dimensions) in our professional practice, thus enriching our therapeutic approach. Through our association, we provide mutual support, exchange knowledge and experience, and collaborate in the expansion and development of PDD internationally.
