Collaboration trainers, founder and LIA

There is clear separation between the training and certification of Logosynthesis® specialists:

  • In German-speaking countries, the Practitioner and Master Practitioner seminars are primarily provided in Bad Ragaz, Switzerland through the Institute for Logosynthesis®. Other recognised trainers provide the seminars in other countries.
  • The founder, Dr. Willem Lammers, continues to develop the system of Logosynthesis and updates the seminars of the two curricula.
  • The LIA takes responsibility for course standardisation and the certification of specialists.


All three stakeholders work closely together. As an overview of their respective activities:
