Peter Drucker has/had a position (Mentor) at Rick Warren

Title Mentor
Notes Through philanthropy and personal engagement, Buford significantly contributed to three of American Christianity’s major landscape shifts over recent decades. First was the rise and proliferation of large-attendance Protestant churches led by innovative, entrepreneurial leaders. Second was the empowerment of Christian lay leaders making a second-career shift from “success to significance” through a “halftime” transition—terms that trace their popularity to Buford’s writings. Third was the formation of the Drucker Institute, a network of organizations designed to further the teachings of management expert Peter Drucker. Drucker not only extensively mentored Buford, but through introductions by Buford, also mentored several high-visibility pastors like Saddleback Church founder Rick Warren.
