During the past decades, IDLS-ProTrainer 1 has been revised every few years to incorporate all the shortcuts and insights gained from conducting the workshop thousands of times. What was initially a two-week program is now reduced to a three- to five-day workshop. Drs. Mary & Peter Esseff has also listened to its clients' needs and integrated many of their excellent suggestions into the training materials.
IDLS-ProTrainer 1 has been used by ESF's Fortune 500 clients all over the world since 1970.
