Brianne Mangold, Au.D.
Brianne grew up in Minnesota and attended Iowa State University, where she studied engineering for her undergraduate degree. Her professional experience includes working with medical devices. She also knows a bit of American Sign Language.
Brianne soon realized that she missed having interactions with patients and decided working in audiology would be a natural fit. She says, “Audiology is a great way to combine medical devices, patient interactions, and use some ASL.”
Brianne completed her extern year at Pacific Hearing Service’s Menlo Park office. She spends half of her time observing audiologists and the other half of her time performing supervised hearing evaluations and hearing aid fittings. Brianne is also learning how to perform earwax removals. She loves helping people and creating relationships with her patients.
In her free time, Brianne enjoys baking, crafts, puzzles, and spending time with her family.

We’re proud to call Ann Hardy a patient: she’s a true Silicon Valley pioneer and a friend.
As a pioneer in computer programming, Ann joined IBM in New York in 1956. Among other projects, Ann worked on one of the first Fortran compilers, which was for STRETCH, IBM’s supercomputer of the day. STRETCH can now be seen in the Computer History Museum.
Ann’s hearing loss journey started when she visited her doctor to complain that she couldn’t hear very well. He referred her to Dr. Deborah Clark at Pacific Hearing Service.

How Dr. Deborah Clark saved Tom from Brain Surgery
Tom went to Dr. Deborah Clark at Pacific Hearing Service for a second opinion, and his own words says, “She saved me from brain surgery.” – She advised that he may not need surgery and her help resulted in him getting the advice of a neurologist that advised that he didn’t need brain surgery.
The rest is history and Dr. Deborah has been helping Tom to achieve better hearing and continue to bring his unique and memorable personality to the world.

Like many people, writer and NPR contributor Debbie Duncan’s children were the first to notice that she had a hearing loss, a friend recommended that she talk to the experts at Pacific Hearing Service. This is where she met Dr. Clark, clinical audiologist at the Los Altos office. “She’s wonderful,” Debbie says. “She figured out that I have a weirdly shaped right ear. She made wearing hearing devices comfortable.”
// MY STORY
They are committed to getting the best results for each patient.
My first experience of a hearing challenge was when I had a sudden and profound hearing loss in my left ear. Prior to visiting Pacific Hearing Service, I didn’t have any concerns, but I was anxious to see what Dr. Baxter and her team could do for me.
My first impression was that Dr. Baxter and her team were extremely passionate about helping those who have lost their hearing and committed to getting the best results for each patient. They are also very thorough and knowledgeable.
They have improved my hearing so that I am not constantly having to say, “What did you say?” or, “Sorry, but I can’t hear you.”My overall verdict of Pacific Hearing Service is that they are excellent.
