She's worked with patients of all ages across a wide spectrum of specialties including amplification, pediatrics, and vestibular assent. In her professional experience, Amy has served as an audiologist for 10 years with PAMF from 2003 to present with prior experience at clinics in Los Gatos and San Jose.

Her taste for fine food is just as worldly with Mediterranean, Indian, and Thai topping her foodie list. When she’s not enjoying the outdoors bike riding with her son Cameron, her indoor passion is sitting with her two cats and scouring the latest fashion magazines.
