Every year a convention takes place organised by the National Guild (NGH) of Hypnotists for hypnotists and hypnotherapists from all over the world in Marlborough Massachusetts USA. This organization was founded in 1950 and it is dedicated to advancing the field of hypnotism. It provides an open forum for the free exchange of ideas concerning hypnotism.
