Antonio Piazza


Recognized as one of the leading mediators in the world.

Mr. Piazza is a 1974 graduate of the New York University School of Law. He pioneered the development of mediated negotiations as the preferred alternative to protracted conflict in complex civil disputes, having successfully mediated the resolution of more than four thousand cases since 1980.

These have included some of the most complex, high stakes and high profile disputes in the commercial sphere. They have involved the world’s preeminent companies, business leaders, and law firms, and have routinely reached resolution in a single day of mediated negotiations.

Individual settlements have exceeded one billion dollars.
