Cliff Hendler is one of North America’s foremost commercial mediators.

Cliff has established many of the benchmarks for dispute resolution in Canada. Over the past 32 years, he has been retained in thousands of matters and is regarded as an individual who is able to assist in the resolution of the most difficult and hotly debated cases. 

His primary practice areas primarily relate to professional negligence/malpractice, personal injury, insurance litigation, products liability, class actions, commercial fraud, defamation, workplace disputes. His cases have included very high profile and delicate matters that have been successfully resolved away from the public eye.

From 1990 through 2010, he was the founder and president of DRS Dispute Resolution Services LP. In 2010 he merged that firm with ADR Chambers. In 2022 he continued his practice under Hendler Mediation Inc.

Cliff is a co-founder of the International Academy of Mediators, an organization that now includes many of the world's top mediators.

Along with his substantial experience in mediation, Cliff has extensive experience in mediation advocacy training. He has been a guest lecturer/speaker at many universities, organizations and public forums across North America and Europe. He co-managed the development of a mediation advocacy program for the American Bar Association National Institute and continues to judge and mediate competetions in North America and Europe.
