About Us

Ian Cull’s Story

In 1995, I was finishing up my Environmental Engineering degree at the University of Illinois, Champaign-Urbana, and was looking for an internship. I landed a job with Chelsea Group, Ltd., one of the few indoor air quality consulting firms in existence at the time. I worked with them as I finished my degree and then again after graduation. I took a long time off to volunteer on water projects in Kenya, but then came back to Chelsea Group.

In 2001, I taught my first indoor air quality class. I loved it. I always had a knack for explaining things in an understandable manner… maybe because my dad was an educator. Through 2004, I balanced my time between performing indoor air quality assessments and teaching classes across the country for Chelsea Group.

In 2004, Chelsea Group’s headquarters moved to Hawaii and the owner allowed me to spin off my training and consulting into a new company. Indoor Science was born!

Both my consulting and training work really started to take off. I became a sought after speaker on indoor air quality topics. In 2006 I was elected to the Board of Directors of the Indoor Air Quality Association. I later went on to serve as the organization’s vice-president from 2008-2011. From 2011-2013, I was hired by the association to serve as its first Technical Director. During my tenure, I authored 50 classes on a wide range of air quality topics which are currently available for purchase through the IAQA University. I also helped launch the association’s YouTube channel.

In the 2010’s our business really took off. We started working on larger projects for larger organizations and hiring more staff.  We were hired as an expert witness on several federal court cases related to indoor air quality. By the time COVID-19 hit in 2020 we were well-positioned to help our commercial clients ensure their workplaces had the ventilation and filtration systems to reduce risks. Due to our growth and potential, our business was acquired in 2021 by Aftermath Environmental Quality Services, a subsidiary of Aftermath Services.  We are currently building out a nationwide network of offices to bring our IAQ consulting services to the entire country.
