Dr. Rebecca Heiss

Dr. Rebecca Heiss helps audiences transform stress, fear, and uncertainty from barriers into fuel for greater resilience, adaptability, confidence, and performance.

Drawing on the science of human behavior and our instinctive responses to pressure, she gives people practical tools to recognize the subconscious fears that can limit decision-making, hold back potential, and make change feel threatening. Through her Fear[less] Stress formula, Rebecca shows audiences how to train their brains to work for them rather than against them—turning pressure into possibility, navigating uncertainty with greater courage, and performing at their best when it matters most. With surprising humor, captivating storytelling, and palpable energy, she makes complex science accessible, memorable, and immediately actionable.

A stress physiologist whose research has been designated “transformative” by the National Science Foundation, Rebecca is the author of Springboard and Instinct and founder and CEO of Icueity, a leadership 360-review mobile application. A former high school and college educator, she was also recruited as a founding member of an innovative charter school focused on entrepreneurial thinking and impact-based learning. Today, Rebecca brings her research and Fear[less] methodology to audiences around the world as a keynote speaker and facilitator of her Fearless Masterclass. She continues to explore how our biology influences behavior and how people can move beyond instinctive limitations to turn adversity into growth and thrive through change.
