Loving what you hear begins with expertise. Your hearing solution is dependent upon the judgment, skill, and experience of our licensed audiologists and audiology aides who will partner with you for one-to-one success. Starting from our cheerful and helpful front office, our staff have always provided our patients with good ol' personalized hearing healthcare since 1997.
Dr. Sandra Wendschlag has been practicing Audiology since 1986. Prior to opening Landmark Hearing Services in 1997, she worked 11 years as a hearing care specialist for a large audiology group. She sees patients in our Sunnyvale location. In 1986, she received her Masters degree in Audiology followed by earning her Doctorate degree through Arizona School of Health Science in 2003.
We are located in the Foothill Medical/Dental Center at the corner of W. Fremont Avenue and Mary Avenue. We are a few blocks off of Hwy 85 - just minutes from Los Altos, Cupertino, Mountain View, Santa Clara, Milpitas and San Jose.

I went to see Dr. Jovona Diggs for the first time for my hearing test and she was absolutely wonderful. She took her time and was super patient, friendly, and knowledgeable!

I will definitely keep going to her for my annual hearing tests.

They work when they want to. Promise follow up and drop you. Hearing aid worked half of the time. They said after selling it to you, we stopped selling this brand because we realized it was of poor quality.

Really satisfied with my time with landmark hearing services Dr. Brandon Cyrus is amazing and is a true hero to me of hearing aid services. Having hearing aids my whole adult life its hard to find caring audiologist like him, he made me feel comfortable and really cared about the quality of my hearing. Dr. Cyrus is a true hero in my book!!! Highly recommend!!!

Brandon helped me with all aspects of getting set up with my new hearing aids. I feel I'm in good hands with his expertise and guidance.

My two year old needed to have a hearing test done to rule out hearing issues and we were referred to Landmark by our pediatrician. Brandon Cyrus conducted a series of tests and by the end of the appointment, even our cautious and suspicious-of-doctors toddler was giggling and smiling ear to ear. I was so impressed by his gentle and friendly demeanor (I'm sure it's not easy to perform a hearing test on a two year old!). He was able to collect the information he needed efficiently and without any tears from our daughter. :)

Would definitely come back if we needed any follow up care.

I've been with Landmark for 10 years now, and am only on my second pair of hearing aids. We flew back from Virginia to San Jose (where we used to live) for a family funeral, and I chose to purchase new hearing aids from Landmark, rather than buy them in Virginia, because I trust Sandra Wendschlag!

I have recommended Landmark Hearing to lots of people because they are a great company. My audiologist there is Amy and she has been amazing. I have gone to her for support many times over the last few years and she is always very helpful and goes far beyond what would be expected. She is patient, knowledgeable, and kind. The office atmosphere is friendly and organized.

I was missing a lot of conversation because my hearing aid needed an adjustment, When I called, they immediately set up an appointment. Normally, I see Sandra but she was booked. Instead I was set up with Amy the day that I called. She was most helpful. I was extremely pleased with her skill, patience and attentiveness.

Overall pretty fast process, timely service and great options at one place (phonac, starkey, widex and oticon). Also - like the bundle of batteries + service for 3 years. You have the option to fit different brands.

I've been to many audiologist for about 49 years since I was 5 years of age. The last great and the real know how to do the job in 1981 because of his retirement. Most specialist did their job within reason but never really understood the depth of how 'hard of hearing' person need to hear.
Today's technology have so much to offer but confused my hearing because I'm so used to analogy. I've tried the compression version of noise control and it didn't work for me.

One of my hearing aid failed yesterday morning and needed to find a new audiologist and found Landmark

These people are great! They helped me get my hearing aids and walked me through the uses of them and calibrated them as well. First I wasn't approved for the financing but they never give up on me, eventually they found away to help me get them. It's been over 10 years since I've had hearing aids and now I'm so happy I can hear again. The doctor was very professional and patient with me and the staff is very friendly.

I was very pleased working with Dr. Amy at Landmark hearing services. The office helped me with the insurance papers and the initial fitting was informative and the units work well. Keep up the good work!

Today (Friday) my right hearing aid quit working at about 1:30PM and Landmark closes at 2PM on Friday. I called them and described the problem and then drove there in about 5 minuets.

Heidi had called the manufacturer and determined it had to be returned with a 10+ day turnaround. She suggested I return both as they were under warranty. She also gave me a new pair loner set and programmed them to my requirements. She also set up my iPhone which controls them and was done before their 2PM closing time. I consider this service "as good as it gets". Thanks Landmark !

It would be very difficult to imagine a better audiologist than Sandra; she is extremely professional. Put it this way: Any time I speak with someone who needs hearing aids, I enthusiastically recommend them to Sandra -- and they always come back and thank me.
