Trusted Hearing Care at Optimum Audiology
Dr. Kristi Mendoza, Au.D., has tested hearing for seniors and Veterans since 1991 and reviews every result the same day.
Hearing Care for Every Stage
Hearing tests, hearing aids from all major manufacturers, and tinnitus and balance care at four offices across Southern and Central California.
Doctor-Led Hearing Care Since 1991
Optimum Audiology is an independent, women-owned practice led by Dr. Kristi Mendoza, Au.D., a Doctor of Audiology who has helped Californians hear better since 1991. Much of that time has been spent with seniors and Veterans, so she knows the moments that bring patients in: missing a grandchild's voice, turning the TV up, or nodding along at church.
Your visit starts with a hearing evaluation in a sound booth, and your results are explained in plain language before you leave. If hearing aids make sense, we recommend them based on your hearing and your daily life, not on which brand is on the shelf.

Four Offices and Hearing Care That Fits Your Life
We see patients in Apple Valley, Jess Ranch, La Verne, and Visalia, and we fit hearing aids from all major manufacturers. If getting to an office is hard, ask about curbside fittings, remote programming, mail-in repairs, or a telehealth visit.
As a VA Community Care and OWCP provider, we help Veterans and federal employees use their hearing benefits. When you're ready, call or text (760) 503-1700.
Hearing Aids Tuned to Your Ears, Not a Factory
Hearing aids only help if they're set for your ears, not generic factory settings. That's why every new fitting at Optimum Audiology includes Real Ear Measurement, a quick test with a tiny microphone that confirms the sound reaching your eardrum matches your hearing loss. We check again at every annual visit, see you for follow-ups in the first month, and most purchases include a trial period so you can hear the difference at home.

Optimum Audiology FAQs
Straight answers for new patients at Optimum Audiology, from booking and insurance to what happens at your first hearing test and after your hearing aid fitting.
The easiest way is to call or text (760) 503-1700. One number reaches all four offices, so you don't need to know which location to ask for. If you'd rather not call, use the Request a Callback form. Share your name, the service you need, and the office you prefer, and our patient care team will call you back to set a time.
If you have an HMO plan, you'll need a doctor's referral for your hearing test. Apple Valley, Jess Ranch, and La Verne are open Monday through Friday from 8:00 AM to 5:00 PM, and Visalia sees patients by appointment only.
Our main office is at 17768 Wika Rd #200, Apple Valley, CA 92307, serving Victorville, Hesperia, Lucerne Valley, and the rest of the Victor Valley. The Jess Ranch office at 19015 Town Center Dr #104, near Jess Ranch Marketplace, is handy for patients coming from Phelan and Oak Hills.
In the San Gabriel Valley, the La Verne office at 2125 Wright Ave #C8 is close to Claremont, San Dimas, and Pomona. In the Central Valley, we see patients at 4004 S Demaree St Ste B in Visalia, a short drive from Tulare and Exeter. If getting to an office is difficult, ask about telehealth, curbside service, or remote hearing aid programming.
Plan on 45 to 60 minutes. We start by asking about your health, your hearing history, and where listening has gotten hard, whether that's a busy restaurant, the TV, or phone calls with family. Then we test your hearing in a professional sound booth with pure-tone testing, speech testing, and otoacoustic emissions (a quick check of how your inner ear responds to sound).
We go over your results at the same visit, using an audiogram (the chart of what you can and can't hear) and plain language. If treatment could help, we walk you through the options. Bringing a spouse or family member is a good idea, since a second set of ears helps when you talk through next steps.
Yes. We accept most major insurance plans and handle the billing and benefit checks for you. We're also a VA Community Care Network provider for eligible Veterans and an approved OWCP provider for federal employees, and we work with Workers' Compensation claims.
For costs your coverage doesn't pick up, we take all major credit cards and offer financing through Cherry and CareCredit. Cherry has 0% APR options for qualifying patients, and the application takes about 60 seconds with no hard credit check. Before your visit, call or text (760) 503-1700 with your insurance card handy, and we'll help you see where you stand.
Your hearing aid fitting takes 60 to 90 minutes. We program your hearing aids, then check them with Real Ear Measurement, which uses a thin microphone in your ear canal to confirm the sound matches your hearing loss. Before you leave, we show you (and any family member who comes along) how to clean, charge, and care for them.
Most patients come back once or twice in the first month for small adjustments as they get used to sounds they've been missing. After that, we see you for annual check-ups, with REM repeated each year. Many adjustments can also be made remotely, and if a hearing aid stops working, we offer in-office, curbside, and mail-in repairs.
