Dr. Baxter became a partner at Pacific Hearing Service in 1986 and both manages and provides audiology services at the Menlo Park office. She completed her clinical doctorate in Audiology (Au.D.) at Salus University, received her graduate training at San Francisco State and UC Berkeley, and is a Fellow of the American Academy of Audiology and certified by the American Board of Audiology. After working as a teacher of hearing impaired children, she changed her focus to audiology services and worked as a research audiologist at the VA Medical Center in Martinez, CA. Prior to joining Pacific Hearing Service Dr. Baxter worked at Stanford Medical Center performing clinical audiology and research.

She has made important contributions to the field of audiology through publications and presentations at professional meetings including authoring a chapter for a textbook about establishing a private audiology practice. She was one of the founders of the California Academy of Audiology and served as its treasurer. Dr. Baxter has also been a consultant for multiple startups and major hearing aid manufacturers including Widex, Starkey, ReSound, Phonak, Oticon, Sonic Innovations, Sound ID and EarLens.

Dr. Baxter is part of a long line of professionals dedicated to the needs of those with hearing impairment. Her grandfather, Frank Baxter, M.D., was the first Eye, Ear, Nose and Throat physician in the East Bay. Many people in the community remember her father, William Baxter, M.D., who retired from his Ear, Nose and Throat practice in Los Altos in 1998. Her daughter, Dr. Ariel Baxterbeck, joined the audiology profession in 2013.

In her hours away from the office, she enjoys hiking, reading, and going to the theatre.

In addition to her clinical responsibilities in Nashville, she was involved with hearing related research and the training of audiology students, medical students and otolaryngology residents.

When she left Nashville, Dr. Clark worked at the Virginia Mason Medical Center Otolaryngology Department and the University of Washington Speech and Hearing Clinic in Seattle, Washington. There, she divided her time between clinical audiology and teaching and supervising audiology graduate students. It was in those settings that she developed an interest in a more global approach to hearing rehabilitation including speech reading, teaching and counseling.

In addition to over 30 years of experience in hearing aid technology and diagnostic evaluation, Dr. Clark is particularly interested in answering the question “Why do some people purchase hearing aids but don’t wear them?” This has led her to make the identification of adaptive and communication strategies a primary goal for her in the fitting process. To further those goals, she began our “What to Expect from Amplification” classes and co-wrote a textbook chapter with Jane Baxter on establishing a private audiology practice.

Away from the office, she enjoys yoga and ballroom dancing.

Our History


Pacific Hearing Service was founded in 1977 by an audiologist who moved east shortly after opening the office. He sold the practice to Jennifer Fargo Lathrop, an audiologist who had big ideas for providing audiology services to the hearing impaired people in our community.


Pacific Hearing Service opens its doors with Jennifer as the new owner and at the forefront of innovation as one of the first private audiology practices in the country. In those days, the business was in a small office on San Antonio Road, near El Camino Real, with no running water! (No, she didn’t have to walk barefooted in the snow 10 miles to get to work. But the lack of running water was a real challenge!) That building has been torn down and replaced with upscale condominiums. We still have patients today who remember seeing Jennifer in that old office.

Things were simpler then. Hearing aids were adjusted with a small screwdriver and appointments were 15 minutes.


Jane H. Baxter partners with Jennifer as co-owner of Pacific Hearing Service. Jane (who had been working at Stanford University) and Jennifer had known and respected each other professionally for years. They were both starting families and shared the workload of operating the growing business. Coincidentally, they both ended up having two daughters over the next few years. They job-shared and Pacific Hearing Service continued to grow. The dedication they showed to their patients earned them a reputation for excellence and referrals came from establishments such as Palo Alto Medical Foundation, Kaiser Permanente, Menlo Medical Clinic, Stanford Hospital and many private physician practices in the area.

Over the next few years, they expanded hiring a third audiologist.


PHS is one of the first clinics in the country to fit digitally programmable hearing aid technology by 3M. It was so cumbersome we needed 3 hours for a hearing aid fitting!


Pacific Hearing Service opens a second office offering audiology services on El Camino Real in Atherton. The practice eventually became so busy that there were now six audiologists in the two offices. The spirit of innovation continues as the practice begins to coordinate with hearing aid manufacturers to beta test new products.


The Los Altos office gets a much-needed upgrade with a move to a more modern and convenient facility at our current location at the corner of First St. and San Antonio Rd. in downtown Los Altos. Each room in this office has running water! Both offices continue to grow and participate in hearing aid research and beta testing.


Deborah Clark moves to the Bay Area from Seattle and is offered a position as clinical audiologist at Pacific Hearing Service. Little did we know she would eventually become a co-owner. Her experience working in major medical centers and universities brought a new dimension to the practice.


Pacific Hearing Service begins to offer Hearing Loss Management classes expanding on the commitment to meet the needs of those who have hearing deficits.


Having continually stayed abreast of the latest in hearing science and technology, PHS audiologists go back to school to earn doctorate degrees in audiology (Au.D.). The doctorate degree became the entry level for the industry in 2007.


The former Atherton office relocates to our current location on Alameda de las Pulgas in Menlo Park. The new office is bigger allowing us to offer more comfortable space for our rehabilitation classes and to display assistive hearing technology such as the CTAP phone demonstration area.


Jennifer Lathrop retires from audiology to do hospice work and Deborah Clark becomes a co-owner. Dr. Clark now manages the Los Altos office while Dr. Baxter manages the Menlo Park office.


Pacific Hearing Service becomes a charter member of a new nationwide audiology cooperative (Entheos) that is committed to promoting best clinical practices, providing humanitarian services around the world, and creating a local nonprofit to serve people in our community with hearing loss who cannot afford hearing healthcare. Jane and Debbie are both members of the board. Debbie is acting president and Jane chairs the best practices committee.


Pacific Hearing Service audiologists, staff, and some local friends provide audiology services around the world like refugee camps in Jordan and the West Bank, Zambia, Mozambique, Guatemala, and Ecuador.


Pacific Hearing Connection is created and receives its 501(c)(3) status as a nonprofit, to provide hearing healthcare to residents of the Bay Area who are underserved and underinsured.


After more than 40 years of providing audiology services to the Bay Area, we have a well-earned reputation for treating our patients with the utmost skill, understanding, and integrity. Our two offices, seven audiologists, and three audiology assistants allow us to be big enough to serve you and small enough to care about you.
