Hannah Millstine

Hannah Millstine, Au.D.


Hannah earned her Doctor of Audiology from Northeastern University. She is an active member of the Maine Academy of Audiology, the American Academy of Audiology, and the American Speech-Language-Hearing Association. She has been a practicing audiologist since 2018. She spent the last three years in the consulting space, working with practice leaders and providers across the east coast. Now she is excited to be back in the clinic working with patients again.

Hannah discovered the field of Audiology during her undergraduate studies at the University of Vermont. During her time in the speech and hearing clinic, she began to understand how important communication is for quality of life and she found her true passion for hearing healthcare. Now, she loves working with hearing aids, and she finds it incredibly rewarding to help patients improve their lives by opening their world back up to sound.

Outside of work Hannah enjoys live music (with hearing protection of course) and exploring Maine’s beaches.

Kelly has always been interested in hearing healthcare as hearing loss is prominent in her family. Seeing her patients’ reactions to trying hearing aids for the first time is her greatest highlight. She loves seeing their eyes light up when they realize they can hear the sounds they were missing.
