When organizational leaders reflect on who has most influenced their careers, they often name a humanistic consultant. The humanistic approach to working with people and organizations spans leadership development, executive coaching, organization development practice, organizational behavior teaching, and efforts to transform and revitalize organizational systems. Its tools are borrowed from diverse sources: its effectiveness relies on a compassionate practitioner with an ability to communicate core principles. Tracing the historical roots of the practice, this book explores the elements that shape humanistic consulting and give it powerful versatility. Insights are offered for consultants, managers and students alike.
