There are a total of 18 recognised Schools of Structural Integration in the World, which have evolved from the work of Dr. Ida P. Rolf. Most practitioners come from 6 main Schools:

Michèle Ménage, Karen Monaghan and Amy Mingasson (visit her website) all trained with Peter Melchior and/or Emmett Hutchins. Peter Melchior and Emmett Hutchins were Ida Rolf's first appointed instructors of Structural Integration. Both Peter and Emmett began studying with Dr. Rolf in 1965. During the early years, there was Dr. Rolf, her son, Richard Demmerle, Rosemary Feitis, Louis Schultz, Peter Melchior, Emmet Hutchins, Jim Asher, John Lodge, Judith Aston and several other teachers trained by Dr. Rolf. She selected Peter and Emmett as the first two teachers to follow in her footsteps in Structural Integration in 1971. Since that time, both have been integral in developing and teaching her work. Many practitioners today have practiced with Peter Melchior and/or Emmett Hutchins, both at the Rolf Institute and at the Guild. The Guild bases its program on teaching and transmitting Dr. Rolf's work through "the recipe," a multiple session method designed to open and balance the human body in its relationship to gravity.


The International Association of Structural Integrators is the professional membership organization for Structural Integration. Founded in 2002, IASI sprang up as a grassroots organization from within the profession to:

  • set standards,
  • move towards certification,
  • insure continuation of a professional identity, and
  • promote Structural Integration’s continued growth as a respected profession in the healthcare field.

Membership in IASI provides assurance that a practitioner is a well-trained and knowledgeable professional who has met strict training standards, follows a professional code of ethics, and maintains a program of continuing education.
