Dr. Ritchie Shoemaker — CIRS, the Protocol, and What It Looks Like in 2026

Shoemaker did what nobody else in environmental medicine had done: he made mold illness measurable. Here's the disease model, the 12-step ladder, the biomarker panel — and the three places patients reliably stall.

Quick answer

The short version

Dr. Ritchie Shoemaker, MD is the physician who defined Chronic Inflammatory Response Syndrome (CIRS) and built the first biomarker-driven treatment protocol for mold and biotoxin illness — a sequenced 12-step ladder verified with labs (C4a, C3a, TGF-β1, MMP-9, MSH, VEGF, VIP) at each step. Integrative You runs a hybrid: the Shoemaker biomarker spine as the objective scoreboard, with Klinghardt-style drainage-first sequencing and titrated combination binders so highly reactive patients can stay on protocol.

The 12 steps, in one screen

Remove the exposure (ERMI / HERTSMI-2, remediation, workplace and car)
Bind biotoxins (cholestyramine, Welchol, or titrated combination binders)
Eradicate MARCoNS (deep nasal culture, compounded antimicrobials)
Correct antigliadin antibodies (3-month gluten-free trial, re-test)
Correct androgens (without premature hormone replacement)
Correct ADH / osmolality
Correct MMP-9 (low-amylose diet, therapeutic omega-3s)
Correct VEGF
Correct C3a (and investigate Lyme when elevated)
Correct C4a
Correct TGF-β1
VIP replacement as the restorative endpoint

Frequently asked questions

Who is Dr. Ritchie Shoemaker?

Dr. Ritchie C. Shoemaker, MD, is the physician who defined Chronic Inflammatory Response Syndrome (CIRS) and built the first reproducible, biomarker-driven treatment protocol for mold and biotoxin illness. His book Surviving Mold and the biomarker panel he developed (C4a, TGF-β1, MMP-9, MSH, VEGF, VIP) remain the objective scoreboard used across environmental medicine.

What is the Shoemaker Protocol?

A sequenced 12-step treatment framework for CIRS: remove exposure, bind biotoxins, eradicate MARCoNS, correct antigliadin antibodies and androgens, normalize ADH/osmolality, MMP-9, VEGF, C3a, C4a and TGF-β1, then restore VIP. Labs are re-checked before advancing to the next step.

Is CIRS the same as mold illness?

Mold illness is the umbrella term. CIRS is the specific biomarker-defined inflammatory cascade that occurs in people whose HLA-DR/DQ genotype prevents normal biotoxin clearance — roughly a quarter of the population. Most CIRS is mold-triggered, but Lyme, ciguatera and cyanobacteria can trigger it too.

Do you follow the Shoemaker Protocol at Integrative You?

We run a hybrid. We keep the Shoemaker biomarker spine because it is the only objective scoreboard in this field, and we layer on Klinghardt-style drainage-first sequencing and titrated combination binders so fragile patients can actually stay on protocol.

How do I know if mold is my root cause?

Start cheap: a Visual Contrast Sensitivity (VCS) screen, HERTSMI-2 dust testing on your home, and HLA-DR/DQ genotyping. If those point the same direction, the full CIRS panel and urinary mycotoxin testing are worth running. A $47 Health Decode gives you a clinician-grade root-cause map first, so you are not guessing which thread to pull.
