This is an independent credential directory. Records are listed alphabetically by the credential holder’s name. Several people can work for the same company; the number of records is not a count of competing businesses.
Before booking, tell the provider whether this is a routine home check or part of a property transaction. Ask about the measurement method, preparation, device placement, pickup and written report. Confirm the full timeline before agreeing to an inspection deadline.
Iowa HHS radon program: Iowa HHS publishes separate measurement and mitigation specialist lists, plus links to home test kits. Use the list for the work you need and match the person's name and credential number.
City names come from the official credential record. Confirm that the provider works at your address; a city listing does not establish a service area.
