Healing the Whole Person
Restoring Health from the Environment to the Immune System to the Soul
Dr. Scott McMahon, MD, FAAP — board-certified pediatrician and nationally recognized expert in Chronic Inflammatory Response Syndrome (CIRS), bridging cutting-edge medical science with spiritual healing and environmental restoration.
World-Renowned Mold Illness Expert Joins MoldCo as Medical Director
Together, solving one of America's most overlooked health crises: Mold Toxicity
"I'm honored to join MoldCo to scale what I've spent years doing one patient at a time — educating and treating people with mold-related illness. We're giving patients answers when the medical system gives them shrugs."— Dr. Scott McMahon, Medical Director, MoldCo
A Complete Approach to Healing
Three Essential Domains
Medical Science
Clinical Diagnosis & Treatment
Precision diagnosis and treatment of CIRS in children and adults. Evidence-based protocols, biotoxin medicine, and the Shoemaker Protocol — delivering clarity where conventional medicine falls short.
Environmental Medicine
Building Health & Remediation
You cannot fully heal the patient without addressing the building. Identifying water-damaged buildings, microbial contamination, and correcting the environmental root causes of CIRS.
Spiritual Integration
Mind, Body & Spirit
Healing requires more than laboratory markers. Dr. McMahon integrates faith-based perspective with clinical expertise — addressing the whole person and offering enduring hope in recovery.

Understanding the Condition
What is CIRS?
Chronic Inflammatory Response Syndrome (CIRS) is a complex, multi-system illness triggered by exposure to biotoxins — most commonly from water-damaged buildings — that affects genetically susceptible individuals. It is one of the most underdiagnosed conditions in modern medicine.
The Trigger
Water-Damaged Buildings
Mold, bacteria, and inflammatory compounds from water-damaged structures are inhaled or ingested, triggering a sustained immune response in susceptible individuals.
The Response
Immune Dysregulation
In genetically vulnerable patients (HLA-DR gene variants), the body cannot clear biotoxins. This triggers a cascade of inflammatory pathways affecting multiple organ systems.
The Symptoms
Multi-System Illness
Fatigue, cognitive impairment, chronic pain, respiratory issues, hormonal disruption, and neurological symptoms — often dismissed as 'medically unexplained.'
The Solution
The Shoemaker Protocol
A precise, step-by-step treatment protocol developed by Dr. Ritchie Shoemaker and advanced by Dr. McMahon — addressing removal, detox, and full restoration of immune function.
Dr. McMahon treats and educates on: Biotoxin Illness · NeuroQuant CIRS · Pediatric CIRS · Post-COVID Syndrome · Mold Illness · Transcriptomic Markers · Indoor Environmental Risk Assessment
