About Gil Boyne

Lived 1924 – 2010 (aged 85). Gil Boyne was an American writer, hypnotherapist and stage hypnosis.

Mark Thomas Gilboyne (October 28, 1924 – May 5, 2010), nom de guerre Gil Boyne, was an American pioneer in modern hypnotherapy.

In addition to his own practice, his main focus was on the training of "lay" hypnotherapists in Glendale, California; and, over some 55 years, he trained thousands of hypnotherapists globally with his Transforming Therapy methods. Many of his students wrote books and created their own hypnotherapy training centers.

Mentored by Ormond McGill — with whom he collaborated for Professional Stage Hypnotism (1977) — he championed the accessibility of hypnotherapy and consistently fought against legislative efforts worldwide to restrict hypnosis to the purely medical professions, which had largely ignored the therapeutic value of hypnosis until Boyne, Milton Erickson, and Dave Elman.

Early life and career Mark Thomas Gilboyne was born in Philadelphia, Pennsylvania on October 28, 1924, to Mark Gilboyne (1903-1976) and Margaret Elizabeth Gilboyne (1908-1983), née Barratt. He had one sister, Margaret Dolores Gilboyne (1933-2005).

Raised in a deeply religious Irish-American Catholic family, his early schooling was religiously focused; something that influenced his spiritual beliefs throughout his life.

He served in the Navy in the Pacific theater during World War II, after which he was assigned to a therapeutic program based on psychoanalysis.

The program was largely ineffective, and his frustration with the approach, his spiritual and religious upbringing, and experience as a stage hypnotist led him to develop the transformative approach using hypnosis. Contemporary influences included Dave Elman, Milton Erickson, Fritz Perls' Gestalt Therapy and Carl Rogers' "unconditional positive regard".

Hypnotism Training Institute

Gil founded and was the director of the Hypnotism Training Institute in Glendale. In 1976, he opened Hypnotherapy training center in the United States offering up to 250 hours of training, including a diploma-offering curriculum in professional hypnotherapy.

Transforming Therapy With his background and experiences and with influences by his contemporaries mentioned above, Boyne developed one of the first programs designed to train hypnotherapists in a regression-based approach. The resulting program, Transforming Therapy, was used for decades to train over 12,000 and possibly as many as 15,000 hypnotherapists globally. The Transforming Therapy method incorporated aspects of Regression Therapy and Gestalt Therapy as well as focusing on the self-healing power of the subconscious mind. It uses a compassionate spiritual approach that simplifies theory in the actual therapy and hones in on allowing the inner mind to construct its own solutions creatively. The approach is generally considered to be rapidly effective.

Boyne continued to train hypnotherapists for over 55 years,

Boyne also founded the American Council of Hypnotist Examiners in 1980.

Hypnotherapist to the Stars From his Glendale offices near Hollywood, Gil worked with many actors throughout his career, including Sylvester Stallone, Lily Tomlin, and Dolly Parton.
