Science-Backed Leadership Expert
I believe the most powerful thing a human being can do in a world designed to turn up the volume is learn to turn it down.
That belief is the foundation of everything I build. Because when the volume comes down, people get clear. Organizations get results-focused. The capacity that was always there: for clearer thinking, deeper connection, and the work that actually matters, finally has room to expand.
The world already carries enough noise. My life's work is proving you don't have to.
The Science Behind the Message
Everybody’s busy but are you actually seeing the results? I help organizations whose people keep pushing harder, get better outcomes that all that extra effort won’t produce.
I'm Dr. Lizette Warner, scientist, keynote speaker, and the
creator of the Capacity Advantage™— the only framework that treats high performance as a capacity problem.
I’ve 20+ years of experience leading teams in highly regulated, high pressure environments where disengagement led to over $20B in recall losses. I didn't just study this problem. I had a front row seat.
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: 20+ years of leadership experience, scientific precision, and the kind of embodied transformation that only comes from living the problem.
The Turning Point
For years, I operated the way most busy people 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 when busy becomes normal?
That question became a decade of research, a coaching practice, a keynote, and a framework used by organizations, 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. I have been featured in Fast Company, The Today Show, and across national and regional media.
What I Do
I work with organizations and individuals in two primary ways:
Keynote Speaking — I deliver neuroscience-backed keynotes for corporate conferences, leadership retreats, and executive events. My signature talk, Turn Down the Volume: From Pressure-Driven to Capacity-Led, gives audiences a practical framework they can use the moment I step off the stage.
Leadership Development — Through the Capacity Code, Dr. Warner works with organizations to build performance capacity at every level — increasing engagement and retention while 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."
