Fauzia Kausar of Sonus Orange

Fauzia Kausar, Au.D., CCC-A, FAAA
CA License: AU2952

Dr. Fauzia Kausar joined Sonus Hearing Professionals in 2013. She has provided diagnostic and dispensing services for different Sonus Clinics.  She is currently practicing at the Orange Clinic, in Orange County. Dr. Kausar earned her Master’s degree in Audiology from Ohio State University (OSU) followed by Doctor of Audiology (Au.D.) from Arizona School of Health Sciences (ATSU). Earlier, she had earned her Medical degree (MBBS) from University of Karachi, Pakistan. She is licensed with California Board of Dispensing and diagnostic Audiology as well as Fellow with American Academy of Audiology (AAA).

Dr. Kausar's interest in Audiology was accidental as she took a class about hearing aids to get away from tedious preparation for Medical Boards. This was back in late 80s when the field of Audiology was still in its infancy and programmable hearing instruments were considered niche technology! Her love for Audiology steadily grew over time as technology transitioned into digital and wireless domains. She has worked with almost all major manufacturers and technology levels over the past 25 years, fitting all age groups. She is involved with different aspects of diagnostic Audiology, such as audiological evaluations, diagnosis and counseling. She works directly with her patients and families in selection, fitting and programming of hearing devices along with post fitting validation, follow-ups and auditory rehabilitation.



Dr. Fauzia Kausar was very friendly and helpful; made my mom feel very comfortable. She also took her measurements so we did not have to come again. The staff took their time to help my mom out with both the test and the fitting! My mom is no longer isolated but wants to socialize again as she can finally HEAR again
