    "Peter in one of the premier Enneagram teachers in the world.  His mastery is informed by several decades of teaching this model coupled with his consistent efforts to develop precision and refine the language when describing the layers and intersecting dynamics found within the Enneagram.  His commitment to his own personal development and background in somatic therapies and counseling provide him with a strong foundation for understanding the psychological landscape of the Enneagram.  Peter’s teaching style is clear, open and receptive allowing his students to contact their own knowledge and inner truth and setting a field of safety and acceptance for their individual experience, challenges and strengths." 
    - Emile Haddad, business coach and enneagram teacher
