An Integrated Approach to Change and Performance
Psychotherapy. Neuroscience. Performance Psychology (Sport & Leadership)
Tina Greenbaum’s work is grounded in the integration of psychotherapy, neuroscience, and performance psychology, with a focus on how people change—and how that change becomes most visible under pressure. Over the course of her career, she has examined not just what helps individuals perform well, but why certain approaches lead to durable internal shifts while others do not.
Psychotherapy
Psychotherapy informs Tina’s understanding of how deeply embedded patterns shape perception, emotion, and behavior. Rather than focusing on insight alone, her
work addresses the underlying triggers that influence response under pressure—supporting durable change in how individuals think, decide, and act.
Neuroscience
Neuroscience provides the scientific framework for understanding how emotional and cognitive responses can be trained over time. Research in neuroplasticity
explains how repeated practice reshapes regulation, clarity, and composure—grounding the work in evidence-based principles rather than theory or belief.
Performance Psychology (Sport & Leadership)
Performance psychology focuses on developing the mental and emotional capacities required to operate effectively in high-pressure environments. Whether in sport or leadership, the emphasis is on cultivating reliable focus, measured response, and steady presence when demands intensify.
The Foundation of Mastery Under Pressure
This book presents the five-step framework that underpins the Mastery Under Pressure course—distilled into a clear, practical guide for developing clarity, steadiness, and effective response under pressure.
“I believe we have the capacity to move through life with greater ease—but only when
we are taught how to relate differently to pressure, emotion, and choice.”
