Gold Country Hearing Center - Rocklin

Dr. Kimberly Bonney is the owner of Gold Country Hearing Centers. She is a Doctor of Audiology who specializes in audiometric and balance testing as well as digital hearing aid assessments.

She earned her Master's Degree in Audiology  from Sacramento State University and her Doctorate Degree in Audiology from Salus University. She has deep compassion for people with hearing loss and remains current with the latest technological advances in hearing health. Kimberly strives to offer the highest standard of service to ensure the best solution for your hearing needs. Her number one priority in enhancing the quality of life for her patients and their families.

With nearly two decades of experience, Dr. Kristin Hallstrom, Au.D., still marvels at the perfect mix of art and science, blended together to help patients improve their quality of life through improved communication and social interactions. To her, audiology is an extremely rewarding profession. She brings diverse experience in clinical and rehabilitative audiology, specializing in diagnostic hearing evaluations, hearing aid fittings, and vestibular assessments for those patients with dizziness/imbalance issues. She takes a team-like approach with her patients to develop an individualized treatment plan to best suit their needs, thus allowing her to establish a personal connection, something that is important to her.  

Dr. Halstrom received her master’s (M.A.) degree from Ohio State University in 2002 and went on to receive her Doctor of Audiology (Au.D.) degree in 2008 from Salus University. She completed an audiology fellowship at the California Ear Institute in Palo Alto, CA, before accepting a position at the University of California, San Francisco (UCSF) Medical Center. Clinical teaching and precepting audiology students had always been a passion of hers, so she left UCSF to join the clinical faculty team at the University of the Pacific (UOP). She then served as the Director of Clinical Audiology at UOP for two years prior to working at Kaiser Permanente. Now, Gold Country Hearing and Balance is lucky to count her as part of their team. 

Outside of the clinic, she enjoys spending time with her husband and three children, skiing, golfing, hiking, mountain biking, paddleboarding, and of course, following Ohio State football (GO BUCKS!).

Dr. Mary Kate Donegan grew up in a family where many struggled to hear and she became aware of the social and emotional impact of hearing loss at an early age. With an inherent desire to help others, she relishes the opportunity to treat the unique needs of her patients. Whether she teaches her patients why they might have trouble hearing in background noise, understanding the cause of their dizziness, or providing hearing aid assistance, she loves that each day brings something new. When she isn’t working, she loves hanging out with her cat, Sylvie, exploring new places, reading, or watching movies and television. She also loves to travel, and each year tries to explore at least one new place in the United States. Dr. Donegan can often be heard encouraging her patients with her motto, "All we can do is give it our best shot.” 

She earned her bachelor’s degree and Doctorate of Audiology from the University of Kansas (Rock Chalk!) and though originally from Chicago’s southwest suburbs, Dr. Donegan is settled in Northern California and a committed to comprehensive and personal hearing care.

Hearing Instrument Specialist Samantha Poulos joins Gold Country Hearing with a commitment to excellent patient care and education. She is a graduate of CSU Sacramento where she majored in audiology and speech-language pathology, with a minor in deaf studies. Samantha believes better hearing can change lives by enhancing not only her patient’s lives, but also the lives of their families. She feels it’s an honor to help others improve their life by treating their hearing loss.
