Jeff Boris. Certified Mirobial Consultant,
Purdue University, B.S. Microbiology

He has 25 years experience as a biologist in the food and pharmaceutical industries.

“As a homewoner and a parent of an asthmatic child, I realized that my knowledge and energy would be best served by educating other people about mold and subsequent hazards of mold in our living and work environments. It brings great satisfaction to give knowledgeable information and offer solutions to homeowners who have the presence of mold in their environment.”


"The mold issue can be confusing and intimidating. Jeff brought his experience as a biologist to our transaction and helped with reasonable and logical solutions. My clients were pleased!"

-Patricia Oxman,
