Description of Practice

Jack Zwicker has extensive experience in negotiation, mediation and arbitration acquired during the course of 42 years as a lawyer in contract, corporate-commercial, property, wrongful dismissal and estate law and in ADR since 2003.

His training and professional skills have helped clients negotiate workable agreements during mediation that are both practical and creative. A mediator's most valuable role lies in getting parties to generate workable options that make for fair and lasting agreements.

His use of straight forward language reflects nine years of classroom instruction at two GTA community colleges, 42 years of group workshop presentations, and writing about mediation and arbitration. He uses 'expedited mediation' to keep the process brief and to the point. This approach minimizes time spent and client costs.

Jack Zwicker uses a singular approach to negotiation, mediation and arbitration. This involves an efficient, fact driven process that allows positive results to be achieved in the shortest possible time frame and at the least possible cost. Given the backlog and the very high costs of civil litigation in our Superior courts, mediation or arbitration can afford clients a process that moves quickly and affordably.
