Membership Rules

The founders of the institute

The institute was founded on April 28, 2004 by Jean-Yves Desjardins and various colleagues trained by him who joined forces.
The founders of the institute are people who have made a financial and professional contribution to ensure the spread of Sexocorporel in Europe and America.  These people deserve our admiration and recognition.
The list of the founders of the iSi can be found here.
