At OpenEar Audiology, we bring personalized hearing care directly to you, providing professional audiology services in the comfort of your home, office, or community setting throughout Roseville, Rocklin, and Lincoln, California.
By meeting patients in the environments where they experience the most hearing difficulty, we gain valuable real-world insight into the situations that matter most. This allows us to better understand, evaluate, and address hearing challenges where they actually occur.

Our mission is to make expert hearing healthcare more convenient, accessible, and patient-centered by combining modern technology with compassionate, individualized care tailored to your everyday life.

Meet Dr. Jennifer Castle, Au.D.
Dr. Jennifer Castle earned her Bachelor of Science degree from California State University, Sacramento in 2008 and her Doctor of Audiology degree from A.T. Still University in 2012.
She has 15 years of experience in audiology, with more than 8 years working in otolaryngology (ear, nose, and throat) at Sutter Medical Center in Roseville. This diverse clinical background allows her to bring a wealth of expertise and knowledge to every patient interaction.
As a CODA (Child of Deaf Adults), with both parents being Deaf, Dr. Castle is fluent in American Sign Language and has a unique lifelong perspective on communication, hearing loss, and the importance of individualized hearing care.
With a passion for personalized service and patient education, Dr. Castle founded OpenEar Audiology to provide a more convenient and comfortable alternative to the traditional clinic experience. By bringing audiology services directly to patients, she helps remove barriers to care while delivering the same high standard of professional expertise expected from a modern hearing practice.
Outside of helping people hear better, she enjoys spending time with her husband and two boys, 3D printing and planting.

Understanding your hearing is the first step toward hearing better. Our hearing checkups assess your hearing, and communication needs to help determine whether hearing aids may be right for you. Testing may include assessment of hearing sensitivity, speech understanding, and hearing in background noise, followed by a personalized discussion of your results and hearing care options.
When hearing aids are recommended, we'll help you choose technology based on your hearing needs, lifestyle, preferences, and listening goals. Your hearing aids are professionally programmed and verified to provide a personalized fit, with follow-up care and adjustments to help you get the most from your devices.
Tinnitus can affect concentration, sleep, communication, and overall well-being. We provide education, counseling, and personalized strategies to help you better understand and manage tinnitus. When appropriate, we can also discuss how hearing technology and sound-based strategies may help reduce its impact on everyday life.
Protect your hearing with custom-fit solutions designed for comfort and performance. We offer custom earmolds, musician's earplugs, noise protection, and other specialty ear products for work, recreation, and everyday use.
Sometimes hearing aids are not the only solution. We can help identify assistive technology to improve communication for television, telephone use, group conversations, and other challenging listening situations. Recommendations are personalized to your hearing needs and lifestyle.
Protecting the hearing you have is an important part of lifelong hearing care. We provide education about safe listening practices, noise exposure, and hearing conservation, along with custom hearing protection for work, music, recreation, and other noisy environments.
