Antonio Piazza is widely recognized as one of the leading mediators in the world today. He pioneered the development of mediated negotiations as the preferred alternative to protracted conflict in complex civil disputes, and has successfully mediated the resolution of more than 4000 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.

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

In 2019, the National Academy honored Mr. Piazza with a lifetime achievement award, in recognition of his industry-changing work in the field of commercial mediation.
