§ 4.1 — Colorado
This page lists 547 people and firms with a current radon testing credential whose official record names Colorado. Each row shows the credential number, the issuing body, and its own verification date. The latest record check on this page was October 13, 2026; other records may have been checked earlier. Source: CO DORA. Verify the number before you hire.
Testing listings are people credentialed to measure radon. Mitigation listings are people credentialed to install a reduction system. Some people appear on both lists when the official file says they hold both. The list is ordered by the city or county on each record. That place is where the record is filed, not a promise about where the person works.

Appendix A
Open the source link on this page and match the name and credential number to CO DORA. Status can change after a record’s verification date. The latest record check on this page was October 13, 2026; check each record’s date. If the official page disagrees with this directory, trust the official page. We do not invent credential numbers.
The U.S. EPA does not certify radon contractors. EPA publishes guidance on finding a qualified radon service provider and points to state programs and national certifications. This directory is not affiliated with EPA. We do not display EPA-certified badges.
Last verified on an individual record is the date we checked its official source. The latest credential check on this page was October 13, 2026; other records may have earlier dates. We refresh the roster monthly. Current means the person appeared as currently credentialed on the source at that record’s verification date. Credentials can expire between refreshes, so follow the source link.
