Antonio Piazza

is 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 world. They have involved the world’s preeminent companies, business leaders, and law firms, and have routinely reached resolution in a single day of mediated negotiation.

Individual settlements have exceeded one billion dollars.

Mr. Piazza’s unique ability to resolve immensely complex issues in intensely focused sessions has proven a resource for reaching closure in time-driven business deals and international negotiations.
