Ann Mau
Ann has been with Pacific Hearing Service for 20 years. You have probably heard her friendly voice over the phone or seen her welcoming smile when walking into the Menlo Park office. Before coming to Pacific Hearing Service, she worked for a major hearing aid manufacturer.
That experience and perspective make her a great liaison between our office, you, and the various manufacturers we work with. As you begin your journey with us, Ann will help you feel safe, heard, and part of the family here as you know she will be one of your biggest advocates. She is able to help with any task, big or small, and if she doesn’t know the answer right away she will find it for you!
