dr bonney, audiologist at Gold Country Hearing

Kimberly Bonney, Au.D.

Owner, Doctor of Audiology

Dr. Kimberly Bonney, Au.D., is dedicated to providing the highest standards of personalized service and care for each of the patients at Gold Country Hearing. Her desire to bring unparalleled service to the hearing industry aligns with her deep sense of compassion for those who struggle with hearing loss. Dr. Bonney knew she wanted to change industry perceptions while helping her patients so she utilized her background as an educational audiologist and went to work for a hearing aid manufacturer so she could learn the inner workings of private audiology practices.

After she graduated from Salus University with her Doctor of Audiology degree, she bought the very first Gold Country Hearing location, determined to bring the very best audiology and hearing aid services to the greater Sacramento area. Through her hard work, genuine compassion, and awareness for those who struggle with hearing loss, the practice has grown into four locations, each of them staffed by doctors of audiology.

Dubbed the “Audiology Angel” by her patients, she makes a sincere effort to connect with patients. She knows that hearing loss can be isolating, so she endeavors to help them stay connected with their friends and family, knowing that a sense of connection is vital for her patient’s well-being.
