Hearing aid advice

ENT is an Ear/Nose/Throat specialists.
The Doctors will be board certified where the Beltone and many other ear places are just trained as Hearing Instrument Specialists. (HIS)
From what I am understanding they do hearing tests, and fit you for hearing aids but can not do actual ear exams and diagnose issues related to health of ear.
I have also noticed on many of the Hearing Aid centers that the HIS personnel seem not stay long resulting in quick turnover where an actual audiologist stay in the field for their career.
