“I’m very impressed with the work of Grant Soosalu and Marvin Oka on the competencies of the brains in the heart and gut and the application of this to leadership. Their action research findings and models are fascinating and advance the work my co-authors and I wrote about in ‘Head, Heart & Guts: How the World’s Best Companies Develop Complete Leaders’.”
