Mediation + Arbitration

Process driven solutions to complex disputes.

Over the past two decades I have conducted more than two thousand mediations, assisting counsel and their clients to resolve complex disputes.

I draw on not only my experience as a mediator but also on over twenty years of experience as a trial and appellate lawyer to create and drive a process that yields results.

As an arbitrator or adjudicator, I bring to bear even-handed and efficient management of procedural matters, and a high measure of legal acumen when making a decision.

Approach


Clear and professional

I listen, clarify issues, and help parties understand their legal positions in order to drive a resolution of the dispute.

Proactive and meticulous

I work to understand the details of the dispute, the dynamics between parties, and the needs that underlie their positions before the mediation commences.

Flexible and pragmatic

I focus on identifying what matters most to each party, and adapting processes that work best for them — including trauma informed practices if required.

Calm, reassuring, and trust-building

I provide a structured, confidential process that helps parties reach resolution in a way that minimizes harm and preserves relationships where possible.

Human-centred and empathetic

I work with the parties and their counsel to slow things down, foster honest conversation, and help everyone feel heard at moments when the conflict or process feels overwhelming.

Dedicated and determined

I explore every possibility in an effort to find a resolution, and follow up after the mediation proper to ensure that I have done so.
