It sets standards for hypnotherapy practice. In 2015 the President of the National Guild of Hypnotists is Dr. Dwight F. Damon, who is also a founding member.
The NGH was founded in Boston, Massachusetts in 1951 by Dr. Rexford L. North
On May 11, 1993, the National Guild of Hypnotists was recognized by the 103rd Congress of the United States for their efforts toward establishing and maintaining a high code of ethics, as well as educational resources regarding hypnosis and hypnotherapy.
In 1994, The NGH chartered a union chapter through the Office and Professional Employees International Union (OPEIU), the National Federation of Hypnotists, Local 104, OPEIU-AFL-CIO, CLC, in order to provide additional legal and political assistance to NGH members by providing access to an official, unionized organization.
In 2000, the organization represented its members in discussions with the state of Indiana, which had set up a committee to license hypnotists.
In August, 2013, Massachusetts Governor Deval Patrick awarded the National Guild of Hypnotists a Governor's Citation, in recognition of their 63rd anniversary. Mayor Arthur G. Vigeant declared August 10, 2013 to be National Guild of Hypnotists Day in the city of Marlborough, Massachusetts in recognition of contributions made to the city, state, and country.
On December 11, 2014, Representative Steve Stockman of Texas recommended the NGH as "one of two organization from which to seek referrals" for hypnosis
As part of ongoing services to the member community, the National Guild of Hypnotists has produced several certification, education, and training programs. In 1990 NGH set requirements of 15 hours of continuing education credits for active certification status; in 1991 the minimum number of training hours was raised to 100, with 75 class hours and 25 hours independent study. That year a Forensic Hypnosis curriculum and the Train the Trainers Program and core curriculum were introduced. In 1992 a continuing education workshop program for NGH members was organized.
In 1995 the Registered Hypnotherapist designation was replaced with the Certified Hypnotherapist designation. In 1998 the NGH Certification Board was created, and a Pediatric Hypnotism curriculum was developed. In 1999 Medgar Evers College – City University of New York began offering a NGH Certification course, an Emergency Hypnotism curriculum and a Complementary Medical Hypnotism curriculum were added.
