A History of Expertise and Innovation

RJ Lee Group has assessed environmental issues since the early 1980s when our Energy Technology Consultants (ETC) pioneered the recognition of specific air quality patterns. We developed a cutting-edge technique for identifying, measuring, and characterizing particles in the air using computer-controlled scanning electron microscopy (CCSEM).

RJ Lee Group has worked with clients in various industries, including the U.S. Environmental Protection Agency (EPA), to assess and provide solutions for environmental factors that could affect our health. Our services have grown over the years, from setting controls for unbound nanoparticles (UNP) to designing and building test chambers to simulate specific environmental conditions.

Today we offer our expertise for our clients’ environmental and compliance concerns and perform rigorous assessment and management of potential environmental risks.
