Audacious leadership.

Three leaders in dentistry are presented as case studies. G.V. Black played a leading role in moving dentistry from a trade to a profession. William J. Gies helped lay the scientific foundation for dentistry. Arthur A. Dugoni has emphasized the human dimension of the profession and built relationships among key constituencies. What these audacious leaders share in common is an expansive vision of dentistry that transcended the confusions of the times and the energy and personal skills to enlist the cooperation of diverse groups in achieving these larger views.
