NEW YORK, NY, November 19, 2025 /24-7PressRelease/ -- Leah M. Lagos has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Dr. Leah Lagos is internationally recognized for redefining the modern understanding of how physiology drives human performance. A board-certified clinical and performance psychologist, she stands among the world's foremost authorities on heart rate variability (HRV) biofeedback—an evidence-based discipline that trains individuals to regulate heart rhythms, emotions, and cognition under pressure.

For nearly two decades, Dr. Lagos has guided the world's top one percent of elite performers—from PGA Tour champions and NBA coaches to hedge fund founders and CEOs of globally recognized brands—in mastering the connection between body and mind. Through her New York-based practice, she has become a trusted advisor to leaders in business, politics, and finance on what she calls biological intelligence: the capacity to harness the body's physiology to inform clarity, adaptability, and decision-making that shapes the world at scale.

"The heart is not merely a pulse or a number—it is a dynamic command center," says Dr. Lagos. "When we study an elite performer's cardiac rhythms in moments of stress and recovery, we uncover the architecture of the nervous system that supports precision, composure, and consistency under pressure."

Her seminal book, Heart Breath Mind (Houghton Mifflin Harcourt), translated into more than eight languages, has become a global reference in performance psychology. The work bridges the scientific principles of vagal regulation with modern neuroscience and biofeedback, revealing how deliberate control of heart rhythms can recalibrate cognition, emotion, and resilience. Through this synthesis, Dr. Lagos has emerged as a defining voice in neurocardiology-based performance training—a field where psychology and physiology converge to cultivate clarity, recovery, and sustainable excellence.

Dr. Lagos earned her Doctor of Psychology (Psy.D.) and Master's in Clinical Psychology from Rutgers University, where she specialized in biofeedback and sport psychology, and her Bachelor of Science in Psychology from the University of Florida. Early in her career, she served as a therapist and health educator at Rutgers University and later as a clinical and sport therapist at the University of Miami—roles that shaped her integrated approach to performance and well-being.

She is board-certified in biofeedback by the Biofeedback Certification Institute of America and licensed in both New York and New Jersey. Dr. Lagos serves as Chair of the Optimal Performance Section for the Association for Applied Psychophysiology and Biofeedback (AAPB) and is a member of the American Psychological Association (APA), Association for Applied Sport Psychology (AASP), and Biofeedback Federation of Europe (BFE).

Her expertise has been featured on NBC's Today Show, CNN, MSNBC, and NBC Nightly News, and profiled in Sports Illustrated, Golf Digest, Harper's Bazaar, Oprah Magazine, and Psychology Today. She has also appeared on The Tim Ferriss Show, StarTalk with Neil deGrasse Tyson, and SiriusXM Doctor's Radio, sharing insights on resilience, recovery, and high performance.

A sought-after speaker, Dr. Lagos delivers keynotes and executive workshops worldwide, helping leaders, athletes, and innovators apply physiological science to high-stakes decision-making and sustainable excellence. She is currently authoring her second book, expanding her groundbreaking framework of autonomic mastery into a model for global decision-making and leadership under pressure.

Dr. Lagos believes that human potential begins in biology—that the heart and nervous system contain the blueprints of our highest capacities. Through deliberate training, that blueprint can be interpreted, refined, and expanded into enduring excellence.
