[2][3] As the oldest and largest hypnotism organization in the world,[4] NGH has approximately 20,000 members across the United States and in more than 93 countries.
[8][9] Guild members do not diagnose, treat, nor prescribe for clients regarding issues related to medical or mental health conditions.
[12][13] Throughout its history, it has received various honors and awards for its accomplishments and today it claims to be the preeminent professional hypnotism association in its field.
[16] In 2000, the organization represented its members in discussions with the State of Indiana, which had set up a committee to license hypnotists.
On December 11, 2014, U.S. Representative Steve Stockman of Texas recommended the NGH as "one of two organizations from which to seek referrals" for hypnosis.
[18] As part of ongoing services to the member community, the National Guild of Hypnotists has produced several certification,[19] education, and training programs.
[21] In 2015, the NGH further amended its credentialing policies and decided that, moving forward, it would only issue the "Hypnotherapist" certification to applicants who were already licensed health practitioners.
[22] The NGH also maintains an updated guide to state law and legal issues regarding hypnotism for public and member education.
The National Guild of Hypnotists has also acted as book publisher for some members,[25] including NGH President Dwight Damon.
