Health Licensing Office

The State of Oregon's Health Licensing Office (HLO), part of the Oregon Health Authority's Public Health Division, is a central licensing and regulatory office that oversees multiple health and related professions. HLO protects the health, safety and rights of Oregon consumers by ensuring only qualified applicants are authorized to practice. HLO reviews and approves applicant qualifications, conducts examinations, inspects thousands of licensed facilities and independent contractors, responds to and investigates consumer complaints, and disciplines licensees who are found in violation of state requirements.

To that end, HLO works with 19 boards, councils and programs in the State of Oregon.

Dental Laboratory Program – Program Implementation Update and Limited Waiver on Enforcement Dental Laboratory Program Implementation Update House Bill 2594 (2025) created the Dental Laboratory Program within the Health Licensing Office (HLO). The bill establishes an operational date of July 1, 2026. The HLO is currently in the rulemaking process for implementation of the program. However, permanent administrative rules will not be in effect by July 1, 2026. As part of the rulemaking process, proposed fees are subject to review pursuant to ORS 291.055 by the Director of the Oregon Department of Administrative Services. Until permanent rules are filed and effective, the HLO is unable to begin accepting applications or collecting fees for Dental Laboratory authorizations. For this reason, the HLO will begin accepting applications and fees after permanent rules become effective. Additional information regarding application availability and program implementation timelines will be communicated as updates become available.
