About the Institute
The purpose and mission of the Institute is to provide a public service to USU students and to larger communities and social units through the broadest outreach of education, training, and research applying the I-System Model and I-System Interventions. The Institute provides annual support for education, training, research and applications of the I-System Model and certifications of Mind-Body Bridging and other I-System Interventions. It also supports expansion and continued research by offering an integrated and wide-variety of stand-alone programs, encouraging participation by and integration with other disciplines, and creates a magnet for innovation and integrative approach(s) to healing collective strife.
The I-System Model, which provides the foundation for both Mind-Body Bridging and Productive Mind, was developed by Stanley H. Block, MD, together with his wife, Carolyn Bryant Block in the late 1990s to optimize heath, wellness, and human performance.
