ABOUT SUSANNAH
Mediator. Lawyer. Mediator. Conflict Strategist. Trusted partner in high-stakes conversations.
Susannah Margison is a mediator with Hendler Mediation, one of Canada’s most respected mediation firms. She specializes in complex civil disputes including medical malpractice, healthcare-related class actions, elder and long-term care negligence, and institutional sexual abuse.
With nearly 15 years of experience across litigation, mediation, and executive conflict coaching, Susannah helps professionals and organizations navigate conflict when composure and credibility are on the line. Her work bridges legal insight, negotiation strategy, and conflict psychology - so clients don’t just survive hard conversations, they lead them.
The Philosophy.
Conflict isn’t a failure. It’s a turning point. The question is whether it leads to damage or to resolution that protects what matters most.
Susannah Margison approaches conflict through a rare lens: blending legal strategy, executive coaching, and real-world mediation experience to help professionals move through difficult conversations without compromising who they are.
Her philosophy is rooted in what she calls strategic kindness: the idea that doing the right thing—and doing it well—is the most effective conflict resolution strategy. She helps clients act with integrity, communicate with precision, and protect their credibility, even when tensions are high.
That means crafting communication that would withstand legal scrutiny, media exposure, or public criticism—and walking away knowing you were the most reasonable person in the room.
Her clients don’t just walk into conversations prepared—they walk in unimpeachable.
Because when your values are clear, your decisions are aligned, and your strategy is sharp, someone being angry with you doesn’t have to be a crisis. It becomes part of the plan.
