Check Out Our latest Book

The book Evaluating Residences Impacted by Smoke and Products of Combustion, published in 2023, is 134 pages long and includes illustrations. The book provides state of the art guidance for evaluating residences that have sustained impacts from smoke, char, soot & ash, and how to appropriately document results.

Over 35+ years, I've seen a thing or two.

Our mission is to help solve challenging environmental & IH problems and to provide cost effective solutions for complex issues.


Indoor Air Quality

We have conducted in-depth investigations to identify indoor air quality contaminant sources and how to mitigate them. The contaminants may be mold or chemicals, or the sources may be poor ventilation design or other factors such as lighting or vibration.


Certified Industrial Hygienist Services

Some of the specific services we provide include evaluation of ventilation systems, surveys for noise, chemical, particulate and biological contaminants and determination of personal exposures to hazardous substances.


Marshall Fire Exposure Assessments

Conducted pre and post exposure assessments of residences impacted by smoke and wildfire debris.


Expert Witness

We have been retained by both plaintiffs and defendants as an expert witness for 15 cases ranging from nuisances to wrongful death cases.  We have been chosen because of our expertise, excellent pretrial work, reasonable cost, and strong communication skills.

"As Practice Commissioner of AIA San Diego, I was particularly well-pleased with the comprehensive information presented in this course. James Lieberman CIH, President of EIS possesses a wealth or knowledge, which clearly took years to acquire. His son, Project Engineer Benjamin, offered constructive comments throughout the program, obviously having been fully immersed in the subject matter for quite sometime. From a personal and professional standpoint, I highly recommend this seminar.  Hats off to Jim and Ben for a job VERY well done!"

"I took James' class in Seattle, and I cannot tell you how informative it was. For someone with zero background in the industry, he gave clear, relative, and concise information, that built up over the duration of the course. He made sure everyone understood the concepts before dismissing us. He was open to any questions. I would highly recommend taking this course if you're looking to be a compliant, knowledgeable and top standard individual in the industry."
