At eighteen, Dr. Ryan Lazarus survived a near-fatal sports accident that left him with Type 1 diabetes, digestive failure, and immune dysfunction. Frustrated by conventional medicine's tendency to treat each condition in isolation, he pursued advanced training across functional medicine, nutrition, kinesiology, and chiropractic care to understand how the body's systems work together.

He went on to spend over two decades in clinical practice, working through thousands of patient cases and serving as faculty at the University of Western States, where he taught metabolism therapy to graduate students. Drawing on that experience across hormone physiology, clinical nutrition, and behavioral psychology, he founded The Lazarus Method to replace one-size-fits-all protocols with personalized, adaptive plans, an approach he also shares as author of the best-selling book The Essential Health Playbook.
