The developer of logosynthesis
Willem Lammers
During his over forty-year search for a simple and effective method in the early 2000s, Dr. Willem Lammers discovered the principles of Logosynthese® and developed a model for healing and development from them. He has always sought to find ways to make the processes in psychotherapy more efficient and effective, and to dissolve distressing memories, disturbing ideas, limiting belief systems, and other blockages.
Dr. Willem Lammers, MSc, TSTA, is a psychologist, psychotherapist and coach for individuals and organizations; in addition, he is a supervisor, lecturer and trainer. For many years he has worked as a Institute for Applied Social Sciences (ias) led, a leading training institute for workplace-related advice in Switzerland.
Willem has worked at the boundaries of body, mind, and spirit since the beginning of his professional development: he is trained in bioenergetics, transactional analysis, hypnotherapy, NLP, and energy psychology.
Since 2005, Willem has been teaching Logosynthese for professionals in the fields of coaching, consulting, psychotherapy, and education in Switzerland and worldwide. He is constantly developing Logosynthese. Currently, the focus of his work is on the further training of practitioners and trainers in Logosynthese, as well as the development of new methods and models.
