Structural Integration Schools Comparison

Structural Integration is a term used to describe a series of massage/bodywork sessions that is based on the work of Ida Rolf who created Rolfing. In 1979, the United States Patent Office granted service mark rights for the word “Rolfing” to the Dr. Ida Rolf Institute,distinguishing “Rolfing” from all other forms of structural integration. DIRI ( is the sole owner of the trademark “Rolfing”, the brand and all its derivatives. To be able to call yourself a Rolfer® and use their trademark, you must attend the Dr. Rolf Institute – DIRI and complete their training.

There are now many schools of Structural Integration that have taken the original work of Ida Rolf and added their own thoughts and methods. The programs listed here are a pathway to certification in Structural Integration by the Certification Board for Structual Integration ( )

The International Association of Structural Integrators provides this chart outlining the various offshoots.

Tom Myers, one of Ida Rolf’s first students provides a breakdown of the variations in the sessions:

The Guild affirms that our primary interest is in human potential and not the palliation of symptoms, and that the miracle of symptom relief is only coincidental with the true goals of Structural Integration. We also vow to promote interest in the “unfinished” aspects of Dr. Rolf’s work and to continue her inquiry into the energy fields of the body and their relationship to balanced structure.

Structural Integration Associations, Certifications

There is also Board Certification in SI through the International Association of Structural Integrators (IASI). Practitioners who display the Board Certified Structural Integrator (BCSI) credential have graduated from an IASI-approved training program and passed a basic competency exam. The Basic Rolfing Certification Program is accredited by The Commission on Massage Therapy Accreditation (COMTA). In order to graduate from an accredited program, all three phases of the program must be attended at the Rolf Institute in Boulder, CO. Regional and International programs are not accredited by COMTA.

The Guild for Structural Integration (GSI) is an association of Structural Integration practitioners and associates who are dedicated to preserving Dr. Rolf’s teaching and work.

Ida Pauline Rolf, PhD (1896–1979) – The woman, The Researcher and bodyworker extradonaire: Where did the The Line and The Recipe come from? Why did she choose 10 sessions? Why did she pick gravity and the line?

The Rolfing Lineage. A few of the early students of Ida Rolf, went on to create their own variation of the 10 Session protocol, always with her blessing. After her death, a battle of the Rolfing Trademark ensued.
