About Dr. Ray
Dr. Ray Haring, Ph.D. is an award-winning educator, author, professional speaker, and research scientist whose life's work has been helping people understand the powerful connection between health, behavior, attitude, and the small daily choices that shape who we become.
His Ph.D. in Nutrition Science with an emphasis in Physiological Chemistry from the University of California, Davis gives him the scientific discipline to speak with authority on health, nutrition, weight, alcohol, metabolism, and wellness. But Dr. Ray's work reaches far beyond science alone.
Through nine books in The Smallest Things Make the Biggest Difference® series, hundreds of hours of televised teaching, and decades of presentations for corporations, government agencies, healthcare organizations, universities, and professional groups, Dr. Ray explores the thoughts, habits, decisions, attitudes, relationships, and everyday actions that influence the quality and direction of our lives.
His gift is making important ideas clear, memorable, practical, and deeply human.
Dr. Ray helps audiences see that lasting change rarely begins with grand gestures. More often, it begins with one thought, one habit, one choice, one story — one smallest thing.
He speaks to audiences who want more than information. They want perspective. They want humor. They want to be challenged, encouraged, and given ideas they can remember and use.
