This chapter comprehensively summarizes some of the significant attributes of servant leadership and its growing influence as a global philosophy and practice. It provides insights into servant leadership at many levels to illustrate the breadth and depth of the servant-as-leader concept. It contains background information on Robert K. Greenleaf, the servant-leader concept, my calling in servant leadership and connections to Robert Greenleaf, a review of some of the characteristics of servant-leaders, and an examination of some of the practices of servant leadership. It may be considered a distillation of my experiences and reflections from forty years as a writer-editor, teacher, and organizational executive in servant leadership. Throughout these many years, my foundational understanding of servant leadership has remained the same as Robert K. Greenleaf’s: The servant-leader is servant first and the best test of a servant-leader: Is one healthier, wiser, freer, more autonomous, more likely themselves to serve others? And what is the impact on the least privileged in society? Will they benefit, or at least, not be further deprived?
