Having worn hearing aids for most of her adult life, Donna has an intimate understanding of the issues hearing aid wearer's face—and how to address them.

Sarah J. C. Nunns


Audiology Doctoral Candidate Sarah J. C. Nunns is in her final year of the Au.D. program at Cal State University-Los Angeles.  She received her Bachelor’s Degree—in Communication Sciences and Disorders—with highest honors from Biola University.

To describe Sarah as a “bright star” in the field of Audiologic clinical care is a woeful understatement.  She will soon begin teaching graduate-level audiology courses at Biola, concurrent to fulfilling her full-time externship with Doctor Cody at Coast Hearing and Balance Center.  At Coast Hearing, Sarah receives great pleasure working together with patients to help them communicate better with their friends and loved ones.

Growing up in a family of musicians, having good hearing is of paramount importance to Sarah—who has played bass guitar for more than a decade.  Sarah likes to find ways of combining her love of music with her passion for Audiology, in addition to expanding her interests in vestibular diagnostics, cochlear implants, and hearing conservation.

In her free moments, Sarah enjoys spending time with her husband, and their dog Pepper, reading a good book, drawing (another passion), and playing her bass guitar.
