Scientist, Professor, Speaker, Teacher of the Smallest Things.
Dr. Ray Haring, Ph.D. has spent a lifetime helping people understand the powerful connection between health, behavior, attitude, and the small daily choices that shape a meaningful life.
A nutrition scientist by training, an educator by vocation, and a storyteller by instinct, Dr. Ray brings together rare scientific depth and uncommon human warmth. His work lives at the intersection of science, wellness, motivation, personal responsibility, and practical wisdom — the place where information becomes understanding, and understanding becomes change.
He is the creator of The Smallest Things Make the Biggest Difference®, a body of work built around a simple but profound idea: the quality of a life is often shaped not by grand gestures, but by the small choices, habits, thoughts, words, and actions repeated over time.
Dr. Ray earned his Ph.D. in Nutrition Science with an emphasis in Physiological Chemistry, Dept. of Molecular Biosciences, School of Veterinary Medicine, University of California, Davis. His academic background provided him with an in-depth understanding of cellular intermediary metabolism, biochemistry, nutrition, cellular physiology, and the scientific foundations of human health.
But his gift has never been limited to knowing the science. His gift is making science understandable, memorable, and useful to everyone.
Over the course of his academic career, Dr. Ray taught advanced nutrition and metabolism, physiology, and health science concepts to generations of students. He became known for making demanding material not only understandable, but meaningful and enjoyable to his students.

Dr. Ray is the author of nine books in The Smallest Things Make the Biggest Difference® series, a collection of brilliant ideas and profound principles that helps us to make positive lasting changes in our lives.
His books are not conventional self-help books, and they are not academic textbooks. They are short, accessible, story-driven works designed to help people think more clearly, live more intentionally, and recognize the power of small changes made with purpose.
Across the series, Dr. Ray returns to a central theme: meaningful change does not always begin with dramatic transformation. Often, it begins with a better thought, a better question, a better choice, a better habit, or a better way of seeing what is already in front of us.
For decades, Dr. Ray has presented to corporations, universities, government agencies, healthcare organizations, professional groups, military audiences, and community organizations. His presentations combine practical insight, humor, and a rare ability to make audiences feel both challenged, encouraged, and entertained.
Audiences respond to Dr. Ray because he gives them more than information. He gives them language for things they already sense but may not have known how to articulate. He helps people see familiar subjects in a new way. And he leaves them with ideas they can remember, repeat, and use.
At the heart of Dr. Ray's work is the core belief that the smallest things we see or don't see — do or don't do — believe or don't believe — will make the biggest difference in the direction of our lives.
Dr. Ray is the founder of HealthSpan Communications®, the platform through which he has published his books, developed educational programs, delivered presentations, and shared his message about health, science, behavior, and human potential.
The name reflects a central part of his mission: helping people think not merely about lifespan, but about the quality, vitality, clarity, and meaning of the years they are given.
Today, Dr. Ray continues to share his work through books, speaking, educational content, and his growing digital platform, including video teachings and story-based reflections drawn from The Smallest Things Make the Biggest Difference®.
His message is timely because it is not trendy. It is rooted in science, lived experience, humor, common sense, and a deep respect for the human capacity to learn, change, and grow.
Dr. Ray's message is for people who desire to understand that the smallest things in their physical, emotional, and spiritual well-being at home, work and play, can make the biggest difference in their lives.
Dr. Ray is available for keynote presentations, wellness programs, leadership events, healthcare education, professional conferences, and customized presentations for organizations that want science, warmth, humor, and practical wisdom in the same room.
