Find a Licensed Hearing Aid Specialist

Use the public database of the Health Licensing Office (HLO) to find a licensed hearing aid specialist. When you access the database, it will open in a separate browser window. When there, take the following steps:

  • Board: Choose "HAS - Advisory Council on Hearing Aids"
  • License Type: Choose "P - Hearing Aid Specialist, Permanent"
  • Status: Choose "Active - Active"
  • Type in city or postal code information to find a licensed specialist by geographic area.

The database does not currently include business contact information (phone and street address). Until it does, we suggest using a print or online business directory. Or conduct a Web search with the specialist's name, key words "hearing aids" and the city or zip code.

About the council

The Advisory Council on Hearing Aids oversees the practice of hearing aid specialists in the State of Oregon. Hearing aid specialists recommend, select or adapt hearing aids and may alter, adjust or reconstruct hearing aids specifications for proper functionality, such as taking ear impressions for proper fit. The Council is composed of:

  • One physician licensed in Oregon by the Oregon Medical Board who is certified in otolaryngology (an ear, nose and throat specialist, or ENT).
  • One member who holds a clinical certification in audiology with the American Speech-Language-Hearing Association and is a member in good standing with that association as well as licensed as an audiologist in Oregon by the Board of Examiners for Speech-Language Pathology and Audiology.
  • Four individuals who are licensed by HLO to dispense, or sell, hearing aids under Oregon Revised Statutes (ORS) Chapter 694.015 to 694.170.
  • One public member who is a consumer of hearing aids and does not possess the professional qualifications of the other members.

Terms of office are four years with the possibility of being reappointed to a second term, however; members are appointed and serve at the pleasure of the Governor.

Happy Valley

Rod Walker gradually began losing his hearing in 1999 and by 2001 had in the canal hearing aids in both ears. As his hearing continued to deteriorate, he received his second and third set of hearing aids (both behind the ear) in 2004 and 2008. He began using FM wireless technology and assisted listening devices to further expand his hearing ability. At the encouragement of his audiologist, he was tested for a cochlear implant and qualified in 2009. For the next year he wore one hearing aid and one cochlear implant. In 2010 he qualified for a second cochlear implant and began a new life of significantly improved hearing.

“My audiologists saved my life. They are people I will never forget. They truly cared about me and made a remarkable difference in my hearing journey,” he says. “I want to help all Oregonians have that kind of hearing experience.”
