The Internal Family Systems model is an extremely popular form of psychotherapy that is increasingly being applied to coaching. Using it, coaches help clients quickly access a state called the Self which is characterized by qualities like calm, clarity, curiosity, and compassion. Then, from that state, clients explore and transform their relationships with the parts of them that are blocking their goals or their vision. Finally, they are more able to lead their personal and work lives from the state of Self-leadership which creates more harmony in their relationships.
The IOC is a global community of coaches.
