Gabriël Anthonio (1963), is chairman of the board of VNN (North Netherlands Addiction Care). In addition to his work as a manager, he lectures at the NHL-Stenden College and is an extraordinary professor at the RUG (University of Groningen) in leadership, organizational development, and sustainability. He started his career working with teenage dropouts in crisis shelters and on the streets, then held various management positions in, among others, a youth institution, a detention center, and in youth care. A common thread in his career is helping organizations in crisis get back on their feet. Anthonio puts leadership development into practice and inspires others to come along on his journey.

Gabriël Anthonio is a sought-after speaker at seminars, conferences, and in organizations, where he shares his ideas, theory, and practices. He appeals to directors and managers, as well as to the employees in the workplace. "I want to demythologize leadership, take off its halo and open it up to everyone."

In The Swiss Army Knife for Leaders you are inspired and challenged to follow your own path in leadership development, to take others with you on the journey, and to work on leading with a positive impact on yourself and your environment. The title of this book refers to the pocket knife of Gabriel Anthonio's grandfather - a teacher, and a great coach for old and young.
