About the Author
Marcus Ettinger, DC, is a clinician, educator, and researcher who has spent nearly four decades helping patients with complex chronic illness. A graduate of Southern California University of Health Sciences, formerly Los Angeles College of Chiropractic, he holds a Doctor of Chiropractic degree and a Bachelor of Science in Human Biology. Since entering private practice in Orange, California, in 1989, he has pursued an intensive study of evolutionary biology, microbiology, human biochemistry, clinical nutrition, diagnostic testing, and integrative approaches to healing. His work has taken him beyond the clinic as a lecturer, consultant, and practitioner serving patients and professionals around the world, from Australia to Ghana. In 2008, working under the name The Digestion Coach™, he developed early clinical protocols addressing H. pylori and microbial biofilms—part of a growing clinical interest in how biofilm physiology contributes to persistent gastrointestinal and infectious conditions.
Decades of clinical observation eventually led Ettinger to a larger question: why do well-chosen treatments sometimes fail, produce only temporary improvement, or even make chronically ill patients worse? His answer became the Ettinger Foundation Protocol (EFP), a phase-based framework built around the principle that recovery depends not only on what is treated, but on whether the body is physiologically ready to respond. EFP organizes recovery according to biological sequence, beginning with foundational regulation and progressing through immune stability, circadian organization, cellular energy production, structural rebuilding, and long-term resilience. Healing in Order is the culmination of that work—a synthesis of nearly forty years of clinical experience, scientific study, and the recurring patterns observed in patients whose illnesses made far more sense once the order of healing was taken into account.
