Peripheral nerve surgeon turned metabolic health educator and coach.

After 15+ years and 3,000+ nerve procedures, I saw a pattern impossible to ignore: metabolic dysfunction was driving the nerve damage I was surgically repairing. Insulin resistance, mitochondrial decline, chronic inflammation — these weren't side notes. They were the root causes.

I was treating the last 10% of a problem that was 90% upstream. So I transitioned out of clinical practice to teach the science most people never hear in a doctor's office.

This channel is education and coaching content — not medical advice.

Three pillars:
- Metabolism — fat loss, insulin resistance, why most diet advice fails after 40
- Nerves — peripheral nerve health and recovery science
- Healthy Aging — the mitochondrial and lifestyle science of aging well
