My new book, The Science Of Becoming is launching 19.03.26

A medical approach to self-transformation

Dr J Crespo’s forthcoming book, The Science of Becoming, A Medical Approach to Self-Transformation offers a medically grounded perspective on personal transformation. Launching 19 March 2026, it goes beyond willpower or motivational slogans, showing how sustainable change arises from the integration of biological, psychological, and relational systems.

Drawing on years of clinical experience across corporate, prison, and palliative-care settings, the book examines how hormones, sleep, nutrition, inflammation, neuroplasticity, emotional patterns, identity, and human connection shape who we become.

The Science of Becoming provides case studies, evidence-based explanations, and practical tools, empowering readers to work with their physiology and relationships to foster meaningful, lasting change — making personal growth a natural outcome rather than a struggle.

Launching Thursday 19th March 2026. Available on Amazon Marketplace.
