Ohio Department of Health (partial — NRPP-verified subset)
Ohio radon professionals
8 people compiled from official sources. 4 measurement only, 0 mitigation only, 4 both. Retrieved 2026-08-29.
If you are not sure you need a pro yet, see when a DIY radon test kit is enough or how to test a home for radon.
This is not a complete Ohio roster. Ohio’s official licensee list is a JavaScript map on DataOhio; there is no published statewide PDF or CSV. These 8 names are the subset that could be verified from public NRPP listings that name an Ohio location (and, where the listing includes it, an Ohio license number). No names were invented to fill the gap.
For a current Ohio license, use NRPP Find a Pro, NRSB, the ODH hire-a-professional map, or contact ODH Radon Licensing (radon@odh.ohio.gov, 614-752-4425). An NRPP or NRSB credential is not a substitute for an Ohio license.
Always verify the credential is still current with Ohio Department of Health Radon Licensing (ODH ID card), plus NRPP or NRSB before hiring. This index does not rank contractors or take referral fees.
