What Is an Indoor Environmental Professional?
An Indoor Environmental Professional (IEP) is a credentialed specialist trained to identify, sample, and document environmental hazards inside buildings — with a level of rigor and clinical precision that standard home inspections cannot provide.
IEPs apply validated sampling methodologies — including spore trap analysis, MSQPCR (ERMI/HERTSMI-2), surface sampling, and VOC monitoring — following protocols developed through ANSI/IICRC S520, ASHRAE, AIHA, and ACAC. Their assessments produce data that is reproducible, defensible, and directly interpretable by physicians treating patients with environmentally acquired illness.
For patients with CIRS, MCAS, Lyme disease, or chemical sensitivities, the quality of an environmental assessment can directly affect clinical outcomes. An indoor environmental professional (IEP) assessment provides the physician-grade documentation needed to guide treatment decisions, remediation scope, and safe re-occupancy timelines.
AirWell’s assessment methodology aligns with the ISEAI IEP Clinical Protocol and the ANSI/IICRC S520 Standard for Professional Mold Remediation.
AirWell’s advisors go beyond certification — each is actively involved in the clinical and standards communities advancing indoor environmental medicine. Their participation in ISEAI, ACAC, and ASHRAE means AirWell’s protocols are continuously shaped by the latest science and practitioner consensus.

What to Expect From an AirWell IEP Assessment
Working with an indoor environmental professional is a structured, science-driven process designed to give you clarity — not just a list of problems. Here is how AirWell’s IEP-guided assessment typically unfolds:
1. Pre-Assessment Intake
Before any sampling begins, your assigned indoor environmental professional reviews your intake questionnaire, symptom history, and any prior test results. This clinical-context step ensures sampling targets the most likely exposure pathways — rather than running a generic panel that may miss the actual problem.
2. On-Site Walkthrough & Visual Inspection
A thorough visual inspection identifies moisture intrusion points, HVAC system anomalies, building envelope failures, and signs of hidden microbial growth. The IEP documents conditions with photographs and notes, establishing a baseline before any air or surface sampling begins.
3. Targeted Sampling Protocol
Rather than collecting samples indiscriminately, AirWell’s indoor environmental professionals apply a Targeted Assessment methodology — selecting sample types, locations, and quantities based on the clinical picture and building conditions. Common sampling methods include ERMI/HERTSMI-2 dust collection, spore trap air sampling, and VOC screening.
4. Laboratory Analysis & Interpretation
Samples are submitted to accredited third-party laboratories. When results arrive, your indoor environmental professional interprets findings in context — comparing indoor vs. outdoor spore ratios, flagging actionable mycotoxin-producing genera, and distinguishing normal background levels from clinically relevant elevations. Raw numbers without interpretation are rarely useful; context is everything.
5. Written Report & Remediation Guidance
You receive a written report suitable for sharing with your treating physician, allergist, or environmental medicine specialist. The report includes findings, a prioritized remediation scope, and re-occupancy criteria — giving contractors a clear standard to meet and giving you a benchmark for clearance testing.
6. Post-Remediation Verification
After licensed remediation is complete, a follow-up Indoor Wellness assessment or clearance test confirms that spore counts and moisture conditions meet the target thresholds set in the original report. This final step is what transforms a remediation project from “probably done” to “verifiably done.”

Common Questions About AirWell’s IEP Team
An Indoor Environmental Professional (IEP) is a credentialed specialist trained to identify, assess, and document environmental hazards inside buildings — including mold, mycotoxins, particulates, VOCs, bacteria, and other contaminants. IEPs apply validated sampling methodologies such as spore trap analysis, MSQPCR (ERMI/HERTSMI-2), and surface sampling, following protocols from ANSI/IICRC S520, ASHRAE, AIHA, and ACAC. Their assessments go well beyond what a general home inspector is trained or equipped to evaluate.
Patients with Chronic Inflammatory Response Syndrome (CIRS), Mast Cell Activation Syndrome (MCAS), Lyme disease, and related environmentally acquired illnesses require assessments that are rigorous, reproducible, and clinically interpretable. AirWell’s IEPs are trained in the clinical frameworks these patients need and work directly with treating physicians to ensure assessment results translate into actionable remediation and re-occupancy guidance.
AirWell’s advisors collectively hold Certified Mold Inspector (CMI), Certified Mold Remediation Contractor (CMRC), AHERA Inspector, Licensed Mold Assessment Consultant (Texas TDLR, MAC1674), Lead Certified Professional, and Project Management Professional (PMP) designations. Several advisors also serve on the boards and standard-writing committees of ISEAI, ACAC, and ASHRAE.
Yes. AirWell’s advisors work closely with physicians specializing in CIRS, MCAS, Lyme disease, SIBO, PANS, PANDAS, and related conditions. Michael Schrantz is a panel member on both Surviving Mold (survivingmold.com) and CIRSx (cirsx.com). JW Biava founded ImmunoLytics Laboratory specifically to support physician-ordered environmental mold assessments, enabling doctors to evaluate potential exposures for their patients.
AirWell’s IEP network covers four regions: Arizona is served by Michael Schrantz and Environmental Analytics LLC; Colorado and Oklahoma by Jeff Bookout; New Mexico by JW Biava; and Texas — Austin and Houston — by Tim Taylor and AirWell Texas. Each regional team provides Indoor Wellness assessments, Targeted Assessments, and professional phone and virtual consultations.
