Voice Dialogue and the ITP


The ITP is known as the leading training institute in the area of Voice Dialogue and Transformational Psychology in Europe. The institute was founded by Robert Stamboliev in 1988 and has brought this innovative approach to the Netherlands and rolled it out to a large number of European countries. Since 1982 Robert studied for years with doctors Hal and Sidra Stone, the developers of Voice Dialogue, with Hal as his mentor.

Until their last European training in 2007 the ITP was the European partner of Hal and Sidra and practically all their European trainings were organized by the ITP, where Robert assembled and led the staff. Almost all instructors and trainers of the various Voice Dialogue training centres in these countries are trained by the ITP. Maria Daniels also played an important role in this process, as well as Ruud Zuurman who led the institute for a few years.

The DNA of the ITP

Voice Dialogue, the Psychology of Selves and Energetics are all part of Transformational Psychology. All training programs of the ITP are based on experiential learning in combination with a clear theoretical foundation. Attention is paid to both power and vulnerability and to the ‘aware ego proces’ of each participant.

All educational programs and trainings have a refined balance between energy work and a solid didactical approach. This balance and the deeply rooted history is in the DNA of the ITP and tangible for all students and clients.

Voice Dialogue is a wonderful method to explore and transform physical, emotional, mental and spiritual energy patterns.  In our two-year Master program professional facilitators learn to intervene on all four levels.

International staff and IVDA

The experienced international staff affiliated to the ITP now consists of 13 Voice Dialogue specialists, originating from various disciplines. This makes the ITP the largest training institute of Voice Dialogue and Transformational Psychology in the world. The ITP is considered as a Master Institute according to the International Voice Dialogue Agreement – IVDA.
