State revokes, suspends licenses, certifications, registrations of health care providers (09-25-2025)

The department's Health Systems Quality Assurance Division works with boards, commissions and advisory committees to set licensing standards for more than 80 health care professions (e.g., dentists, nurses, counselors). Information about disciplinary action taken against medical doctors and physician assistants can be found on the Washington Medical Commission (WMC) website. Questions about WMC disciplinary actions can be sent to [email protected].

Information about health care providers is on the agency's website. Click on "Health Care Provider Lookup" under the "Find it Fast" section of the Department of Health website (doh.wa.gov). The site includes information about a health care provider's license status, the expiration and renewal date of their credential, disciplinary actions and copies of legal documents issued after July 1998. This information is also available by calling 360-236-4700. Consumers who think a health care provider acted unprofessionally are also encouraged to call and report their complaint.
