Areas of Practice

The primary focus of my practice is on the successful resolution of international commercial disputes through alternative dispute resolution(ADR). Of the many forms of ADR practiced, I concentrate on arbitration and mediation.


Acting as Arbitrator (either as sole arbitrator or member of a panel), selected by the parties to commercial disputes either directly or through the rosters of the various international arbitral organizations, to which I belong.


Acting as mediator or third party neutral, selected by the parties to commercial disputes either directly or through the courts or though the various mediation organizations with whom I work.


Over the past 30 years I have practiced in various domestic and international settings in both in-house and external counsel roles.
