Tai was born in Vietnam, but has lived in Southern California for most of his life. He completed his Doctoral degree at A.T.

He’s currently a provider at Sonus Hearing Care Professionals in Fountain Valley where he has been serving the adult and geriatric community. He is bilingual in Vietnamese and English, therefore he has been providing services for the Vietnamese community as well. His goal is to provide best practice care to his patients with a warm and loving heart.



Hearing aids have changed our lives completely. We are able to communicate much better. We don't argue with TV volume. We are able to enjoy going out and going to social events. The Sonus personnel are knowledgable and extremely helpful.

Robert R, Sonus Patient

I love my hearing aids. I put them on immediately went getting up and don't take them off until I go to bed! I feel lucky that the gentleman who made them for me was so great and wanted them to fit my ears perfectly. I recommend this Sonus office to my friends and family. Thank you for allowing me to hear again.
