Larry Gust is an electrical engineer by training.  He is a building biologist out of personal necessity.

Larry is also a pioneer in the field of Building Biology and a leading expert in the intersection of engineering and environmental health. With a career spanning over four decades, he specializes in identifying and mitigating the hidden "sick building" factors that impact human wellness.  We have worked with Larry many times over the years and even followed him as he performed home inspections.

• Larry is training the next generation of  Building Biologists. Since 1996, Larry has been a lead instructor for the Building Biology Institute (BBI), the organization responsible for establishing the gold standard for healthy indoor environments. He is the expert that other experts go to for training.

• His background in engineering: Before entering the wellness space, Larry spent 25 years in management at Dow Chemical and Mobil Corporation. This high-level background in manufacturing and quality management provides the technical rigor behind every countermeasure he recommends.

• How he came to be a building biologist. I've seen this with many people.  Your personal experience with tech toxins, leads you find solutions where there typically aren't solutions.  In 1987, both he and his wife became ill due to toxicity in their home and work environments. His search for solutions for himself and his wife, led him to building biology and an important pivot in his career.  Today, his deep understanding of what clients are experiencing with tech toxins in their homes, along with his technical mastery, makes his work so effective.

• Key Credentials:

  • Electrical Engineer.

  • Certified Building Biology Environmental Consultant (BBEC).

  • Electromagnetic Radiation Specialist (EMRS).

  • Senior Faculty Member, Building Biology Institute.

Larry’s expertise includes the areas of in indoor environmental inspection, measurement and interpretation of environmental parameters, safe building practices, air purification systems and water purification systems, and electromagnetic radiation countermeasures.
