Dr. Lisa Leit

Lisa Leit, Ph.D., MCC is an expert in developmental psychology, an ICF Master Certified Coach, and the founder of Happy Whole Human® — and the creator of Human Systems Architecture™, a way of measuring and redesigning how people, relationships, teams, and organizations actually work. Recognized as a Top 100 Visionary in Healthcare by IFAH and honored as Global 100 Executive Coach of the Year, she has spent more than 20 years helping individuals, couples, families, and leadership teams live happy, whole lives.

Lisa's work rests on a simple truth: there is a "we" in wellness. Grounded in human ecology, her systems approach helps people cultivate both inner coherence — alignment within the self — and outer coherence — healthy, mutual relationships and well-functioning teams and organizations. She doesn't believe transformation should be mysterious or accidental; she believes it can be measured, modeled, and intentionally created. What looks like magic, in her work, is really human systems functioning the way they were designed to. As a coach, she blends conventional training with holistic, integrative techniques, including hypnotic coaching, to help people energize their evolution; as a mediator, she guides individuals, families, and organizations as they reconcile conflict and negotiate agreements outside the courtroom.

Today her life's work has grown into the Human Systems Architecture™ Series — a complete, evidence-based coaching ecosystem that unites five validated assessments (led by the university-validated, 28-dimension Holistogram™), eCourses, privacy-first AI coaching copilots, ICF-accredited coach training, an app, and 16 books under one model, serving individuals, couples, teams, and organizations. The approach is trauma-informed, validated for outcomes by the Validation Institute, and grounded in ecopsychology, human ecology, neuroscience, and Lisa's doctoral research at the University of Texas at Austin.

Lisa writes, coaches, and teaches from both Austin, Texas and Barcelona, Spain. She offers a DIY Happy Whole Human online program alongside individual, couples, family, and team coaching, and she mentors and certifies coaches through the Happy Whole Human Institute of Holistic Wellness, accredited by the International Coaching Federation (ICF) and the American Council of Hypnotist Examiners (ACHE).
