About My Guest:

My guest for this episode is JW Biava.  JW Biava is the Owner and CEO of ImmunoLytics, an environmental laboratory that specializes in assessing indoor environments for mold contamination and provides consultations with clients over how best to reduce any contamination found.  JW's interest in environmental mold exposure grew tremendously after determining that high levels of mold in his own home were a major contributor to his various illnesses, as well as those of his family members.  JW was introduced to Dr. Walter Hayhurst R.Ph. in the early 2000s, at which time he began working on the development of natural botanical products aimed at improving mold contaminated environments. These products were taken to market though CitriSafe, BioBalance, and Micro Balance Health Products.  JW created ImmunoLytics Laboratory to address indoor air quality issues related to mold. ImmunoLytics began by assisting a few doctors who wanted to determine if mold exposure in their patients’ homes could be contributing to their health issues.  ImmunoLytics has since grown to service hundreds of doctors and tens of thousands of patients around the world on a yearly basis.  JW holds several certifications including Certified Mold Inspector, Certified Mold Remediation Contractor, AHERA Inspector, Lead Inspector, Radiation Safety Officer, Shipper of Hazardous Materials including Radioactive Materials, Thermography, and more.  JW currently spends his days running a suite of businesses aimed at providing solutions for those with environmentally acquired illnesses.  JW has been a featured speaker to hundreds of thousands through events such as The Toxic Mold Summit, The Candida Summit, The Toxic Mold Masterclass, as well as numerous podcast appearances.
