About Us

Hearing Care Services

Our hearing is so important, since it connects us to our family, friends, coworkers and the world around us! Left untreated, hearing loss can have devastating effects on our emotional, social and physical well-being. When you come to Advanced Instruments Hearing Aid Service, we will discuss the communication challenges you face in your daily life and the options available to help you achieve better hearing at a reasonable cost. Whether you are needing a repair of your present aids or requiring new instruments, your needs will be thoughtfully considered and recommendations thoroughly explained. 

If new hearing instruments are needed a plan is agreed upon, the instruments are ordered and an hour long programming and training session is scheduled. At your delivery, the instruments are programmed for your hearing needs, their function thoroughly explained and you get to practice inserting and controlling them. A follow-up appointment is scheduled one week later.

At your first and second follow-up appointments your progress is carefully monitored, adjustments made and counseling performed to ensure your smooth transition to being a good communicator once again. We provide a 45 day return or model change guarantee for your peace of mind.  At Advanced Instruments you will always be scheduled for another appointment upon your departure. All quarterly cleaning appointments, yearly retesting, programming and drop-in emergencies are free of charge for up to 5 years.

We work with all insurances, workman’s compensation, Partnership Health Plan, Medi-Cal, Department of Rehabilitation and Ear of the Lion. No one is turned away for lack of funds. Such is our commitment to our community.

Patient Testimonials

I’ve worn hearing aids for 30 years. Roughly five years ago, I got my first digital aids at Advanced Instruments. A week ago, I upgraded to the Resound Quattro 9, and I couldn’t happier. The Quattro 9’s sound has a sharpness or crispness that is far superior to my previous aids, and I can now hear accurately in venues where, previously, I could hear, but I couldn’t discern what was being said. Again, the Quattro 9s are a terrific advancement in hearing technology. As always, Bonny Kuhfal and her staff were a pleasure to deal with.


Dave S.
The hearing aid specialist who took care of me has really helped me hear better. It took me a few weeks to get comfortable with my new hearing aids, but she was very patient with me and I am hearing so much better. Bonny was very helpful all along the way.

What a wonderful office! I am allowed to bring in my little dog and not have to leave her in the car. They even have treats for our dogs. Something to chew on instead of my hearing aids!. The staff is knowledgeable about hearing health and go out of their way to assist in any way they can.

Dave C.

The office really cares about their patients. This is clear as soon as you arrive. The prices are better than most and the care is ongoing, free office visits and cleaning every 3 months.
