The Origin of
Modern life has removed many of the natural stressors that once shaped resilience. FOCA was created to thoughtfully reintroduce structured challenge and recovery in a safe and scalable format. The result is a system that allows individuals to rebuild adaptive capacity through progressive exposure to physiologic stress.

I remember feeling drawn to medicine as a kid. Operating rooms, trauma suites, the surgical intensive care unit — that is where I trained, first at the University of Connecticut and then through my residency at The Johns Hopkins University Hospital. The hours were long, the stakes were absolute, and I loved it. We were extraordinary at keeping people alive through the worst moments of their lives. I believed we had the answers.
The reckoning came quietly, over years. The patients I was watching recover from trauma and acute illness fared much better than those facing chronic medical conditions. Those patients were not transformed over time, they were diminished. Medication lists grew. Diseases persisted and quality of life diminished. We were brilliant at acute intervention but ineffective improving the chronic diseases of today. I knew something was missing. I just did not know what.
So I kept learning. Not through formal channels — I had completed everything formal medicine required — but on my own, driven by the growing conviction that the answers existed somewhere outside what my training had covered. I began exploring other countries' approaches to chronic disease. I dove deep into nutrition, detoxification, and natural hormone restoration. I read and studied relentlessly, and started applying what I was learning in side practices I built while continuing to work full time. The results were encouraging—patients were recovering from autoimmune disease, diabetes, chronic fatigue, and cancer — not just managing their conditions but genuinely improving.
Then I discovered more about oxygen therapies. As an anesthesiologist, oxygen delivery had been central to my work for years. I thought I understood everything about it. I was wrong. The science and principles of how we breathe and deliver oxygen where and when it's needed in the body matter deeply. These discoveries opened an entirely new dimension of clinical thinking and still represent some of the greatest health improvements I have seen. The Bohr effect, the relationship between CO₂ tolerance and oxygen delivery, and therapies like hyperbaric oxygen and exercise with oxygen therapy are not fringe ideas. They are deeply science-based and overlooked by mainstream medicine because they do not fit neatly into a pharmaceutical model.
The final piece arrived when I discovered Hormesis — the science of adaptive challenge. The principle that the right stress, applied at the right dose, does not weaken the body but strengthens it. Cold exposure, heat, high-intensity exercise, intermittent fasting, oxygen variation — all work through the same fundamental mechanism: controlled stress followed by complete recovery produce adaptations that cannot be achieved any other way. The scientific literature was extensive and unambiguous. Hormetic interventions hold the keys to help overcome chronic disease. The challenge was that nobody had built a system that could be safely and consistently delivered to real people struggling with all types of medical conditions.
That is the problem I spent the next five years solving. Because the insight that took the longest to arrive — and that I believe is the most important clinical contribution FOCA makes — is this: you cannot challenge a compromised person. You must prepare them first. The assessment system at the heart of FOCA exists because of that insight. Before any therapy is delivered, we need to know exactly where someone is physiologically — their Foundation, their Oxygen efficiency, their Challenge readiness, and their Autonomic flexibility. Those four pillars determine everything that follows.
Many years after my formal medical training have been spent searching for the most powerful, natural, and science-based determinants of health. The result is FOCA. It is the synthesis of everything I learned that was not in the textbooks — the foundational requirements, the science of oxygen delivery, the hormetic principles, and the autonomic training — organized into a system that is assessable, scalable, and safe for anyone from a compromised patient to a highly trained athlete. FOCA casts a wide net by design. It works across what I call the Disease to Vitality Continuum — helping to reverse disease, promote longevity, and enhance athletic performance and recovery. The body knows how to heal and adapt. Our job is to create the conditions that allow it to do so — systematically, progressively, and with the clinical rigor that distinguishes a real program from a wellness trend.
Dancing with Darwin: Challenge Therapies for Optimal Health

Humans have achieved something no other species has ever experienced: the ability to live in a state of constant comfort, but our bodies remain hard-wired for coping with intense physical and environmental challenge.
This book introduced Dr. Saltzman's natural model to overcome disease, promote longevity, and enhance athletic performance.
