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

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 people aren't bad at change. They're out of practice.

Over the last twenty years, we've engineered the small, manageable uncertainty out of daily life — GPS instead of a wrong turn, predictive text instead of a blank page, one-click everything instead of figuring it out. Each removal was a genuine convenience. Together they took away the reps.

So when something genuinely unpredictable arrives — an AI rollout, a restructure, a market nobody can forecast — the response isn't curiosity. It's a freeze - a panic. People go quiet in meetings. They stop volunteering for the ambiguous project. They wait for things to settle, and things never settle.

There is a reason most organizations are failing to navigate change successfully, and it has nothing to do with their communicaiton or the tech rollout and everything to do with not serving their people by meeting them where they are - scared to make a move.

The Promise

You can't reason someone back into a capacity they've stopped using. You have to rebuild 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 put the reps back. Not by removing uncertainty, which isn't a reality, but by rebuilding the tolerance for it that modern life quietly took away.

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.
