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.

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.
