For many years, Mario Marrone has been running courses and workshops in different countries on a variety of topics, all based on attachment theory. Its presence has spread to the United States, the United Kingdom, many European countries and Latin America, but its main zone of action is England and Spain.

Topics of their recent experiential workshops include “attachment and sexuality" and "attachment and psychodrama". Theoretical-experiential workshops have focused on the clinical applications of the Adult Attachment Interview (AAI). He also holds seminars to discuss clinical cases for psychotherapists.

Normally his workshops and seminars are advertised by the organizing institutions.
