Anyone interested in taking Landmark courses should research this privately owned for-profit company founded by Werner Erhard and now run by his brother, quite carefully before becoming involved.
Landmark, previously known as EST, has a deeply troubled history of bad press, complaints and repeated lawsuits for personal injury.
See the following sections within the Institute database.
Constant complaints come in to The Ross Institute about Landmark and its programs from families, participants and concerned individuals.
There is no sceintific peer-reviewed and published study, which demonstrates that Landmark has any lasting benefits.
The benefits claimed by Landmark devotees are subjective and/or based upon anecdotal stories and testimonials. They do not represent scientific research.
Companies that have offered Landmark courses to their employees have often come under severe criticism and at times have been sued.
Employees often don't appreciate having a philosophy imposed upon them within a course format through the workplace.
Obviously, each person has his or her own personal philosophy and/or religion, which is a private matter.
Landmark is simply the philosophy of its founder Werner Erhard. And the touted Landmark "technology" is little more than downloading that philosophy (drawn from several sources and not really original) through a mass marathon training program.
And Mass marathon training like Landmark is itself quite controversial.
Such training often includes coercive persuasion techniques.
Based upon its troubled history, constant complaints, lawsuits for personal injuries I would not recommend Landmark to anyone under any circumstances.
Obviously there are much safer less controversial alternatives.
There are college level classes focused upon self-improvement and support groups sponsored through nonprofit community centers, social service agencies, churches etc.
For personal problems and issues, there are licensed mental health professionals that provide counseling one-on-one and/or in group sessions.
Unlike Landmark session leaders these professionals are accountable to State licensing boards, professional associations and typically possess relevant educational credentials and certification.
