The Science Behind the Message
Most high performers are praised for handling pressure.
What no one measures is what it costs them.
I'm Dr. Lizette Warner, a PhD scientist and leadership performance expert who helps ambitious high performers turn down the volume on stress — so they think clearly, lead decisively, and sustain their performance without burning out.
My work sits at the intersection of neuroscience, executive coaching, and leadership development, and it is grounded in a rare combination that few in my field can claim: scientific precision, 20+ years of executive leadership experience, and the kind of embodied transformation that only comes from living the problem.
The Turning Point
For years, I operated the way most high performers do — by pushing through.
The results were real. So was the cost. A Hashimoto's diagnosis, an autoimmune condition I now understands as my body's response to years of unregulated performance. That diagnosis forced me to stop outsourcing regulation to willpower and start asking a different question: what actually happens inside a high performer when the volume gets too loud?
That question became a decade of research, a coaching practice, a keynote, and a framework used by executives, leadership teams, and high performers across the country.
The answer — and the practice I built from it — is what I bring to every stage and every coaching engagement.
"Pressure may drive results, but capacity determines how long you can sustain them."

Credentials & Experience
I hold a PhD in Biomedical Engineering and am credentialed as a Master Certified Coach (MCC) through the International Coaching Federation — the field's highest designation, held by fewer than 4% of coaches worldwide.
I bring more than 20 years of executive leadership experience across science, health technology, and organizational development, and am a faculty member at the University of Texas at Dallas, where I teach in the Executive Coaching Program at the Naveen Jindal School of Management — specializing in neuroscience of performance, ethics, and business development for coaches.
I am also the author of Power, Poise & Presence: A New Approach to Authentic Leadership and a TEDx speaker. My work has been featured in Fast Company, Today, and across national and regional media.
What I Do
I work with organizations and individuals in three primary ways:
Keynote Speaking — I deliver neuroscience-backed keynotes for corporate conferences, leadership retreats, and executive events. My signature talk, Turn Down the Volume: A New Framework for Pro-Active Performance in a Reactive World, gives audiences a practical framework they can use the moment I step off the stage.
Executive Coaching — Through my company Lizette Warner International, I partner with senior executives, organizations, and high-potential leaders navigating complexity, high-stakes decisions, and the performance ceiling that sustained pressure creates.
Leadership Development — Through Trust & Leadership, the coaching and leadership development company she co-leads as Chief Coaching Officer, Lizette works with organizations to build performance capacity at every level — reducing burnout, shortening time to impact, and building cultures where people can actually sustain the work.
I had worked with other coaches before, but the real issue was missed. In less than a month, Lizette helped me measure and identify the actual issues. Together we built a clear, trackable plan with actionable next steps.
For the first time, I was able to make real progress."
