Featured Workshop

Knowing Ourselves: Exploring the Enneagram
Saturday, April 21, 10:00am - 5:00 pm
Peter O'Hanrahan and Carole Pertofsky
Location: Stanford School of Medicine, Wellness Program

We are complex individuals, yet, at our core, systematic motivational patterns ignite our strengths and trigger defenses. Whether in our personal lives or in organizations, we can sometimes be baffled by our own impulses, as well as the behavior of others.
Discover these hidden patterns and explore courageous questions that can drive success in life: “What makes me come alive? What makes others tick? How can I increase my capacity to succeed and flourish?”
The Enneagram has been used for decades as a method to increase self-understanding and for self-development. It is also used as a method to improve workplace dynamics by teaching strategies that build rapport and empathy and reduce unproductive conflict. Click here for more information and to Register.

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.
