Named to Global Gurus’ Top 30 Motivational Speakers for 2026 — ranked alongside Tony Robbins, Simon Sinek, Mel Robbins and Les Brown. See the ranking.

Dr. Rebecca Heiss is a stress physiologist and keynote speaker on leading through change and uncertainty. She helps leaders and teams turn disruption, AI anxiety, and constant change into focus, confidence, and performance.

The Problem

Your brain doesn't know the difference between a tiger and a Slack notification about another AI rollout. It reacts to both the same way — and it's not built for a world that sends the "tiger" alert forty times a day.

That's not a discipline problem. It's not a mindset problem you can meditate your way out of. It's biology doing exactly what it evolved to do, in a world it was never built for.

AI disruption, restructuring, leadership transitions — none of it waits for the last change to settle. Most change-management approaches respond with more of what's already not working: more communication, more "embrace the discomfort" messaging, aimed at people whose nervous systems are already maxed out.

The Promise

You can't out-communicate a stress response. But you can retrain it.

In this keynote, Dr. Rebecca Heiss — a stress physiologist whose research was designated "transformative" by the National Science Foundation — shows leaders and teams how to tell the difference between a real threat and a false alarm, and what to do with the false alarms so they stop costing focus, confidence, and performance.

This keynote is built for organizations in motion.

Whether you're absorbing an AI integration, working through a merger or restructure, navigating economic uncertainty and hiring freezes, rebuilding after layoffs, shifting return-to-office policy, managing leadership succession, or simply asking people to perform while the ground keeps moving — Rebecca gives your leaders and teams one shared, science-backed way to respond instead of brace.

Overview

Dr. Rebecca Heiss keynote on training the brain's stress response, with tiger imagery on stage

Using her Fear(less) Stress Formula, Rebecca walks audiences through the same three-step process she's used with organizations navigating AI integration, restructuring, and market uncertainty:

Invite the Tiger in for Tea — get curious about the stressor instead of fighting it. Is it a real tiger, or just something that looks like one?

Choose Your Own Adventure — reframe the threat as something you have a say in.

Springboarding Toward Action — convert the (now-manageable) stress response into forward motion that serves you (and others!).

It's science, but it doesn't perform like a lecture. Expect real stories, audience participation, and the kind of humor that makes a room comfortable enough to actually hear something uncomfortable

The audience will leave able to:

  • Recognize when their stress response is reacting to a "tiger" that isn't real

  • Rapidly transform AI-era anxiety and change fatigue into usable energy instead of shutdown

  • Adopt an adventure mindset that builds resilience into how the team handles the next disruption, not just this one

  • Engage with difficult conversations and decisions with less fear driving the reaction

The change isn't going to wait for your people to feel ready.

Teams leave with a repeatable way to tell a real threat from a false alarm — so the next AI announcement, reorg, or leadership change doesn't cost you a week of frozen productivity. Fewer costly mistakes. Less disengagement. A team that adapts instead of stalling.

So what if they didn't have to be ready?
