Indoor Air Quality Consultants Education and training


We offer you scientifically sound, unbiased evaluations.  We aren’t compromised by slanting our evaluation of your problem or situation by wanting to sell you something (a product that supposedly solves the problem we identified or a service offered in-house) or by looking to refer you to someone else for a commission.


Our principal investigator, Roderick Thorpe, has 20+ years of experience in the indoor air quality/environmental evaluation field.  He has examined a wide range of problems and situations in thousands of large and small buildings of all types (including residential, commercial, institutional, governmental) from a single closet in a house to an entire large high rise building or a large school or a small office.
