Services

Audiology and Hearing Aid Center’s primary focus is to create an unsurpassed patient experience through our caring and highly trained doctors of audiology.

We do not do hearing tests like big retail chains like Costco, Beltone, or Miracle-Ear. We provide world-class diagnostic hearing and balance evaluations and treatment and use advanced testing to understand our patients’ hearing and balance.

Did you know that two hearing tests from two different people can look exactly alike, but your ability to hear can be completely different? A retail hearing aid store will likely give you and your friend the same hearing aids with the same programming. But we don’t do that. We perform proper diagnostic testing, and when we fit hearing aids, we follow our proprietary 30-day hearing aid fitting protocol to guarantee 100% patient satisfaction using real ear measurements. We customize it exactly for you.

Our hearing aids are also world-class. We select from the top manufacturers across the globe, with a preference for American made hearing aids when possible. We make custom impressions to match your ear perfectly. And we carefully follow-up with our patients regularly to ensure ongoing satisfaction.

Of course, we also offer boutique hearing aids like the IIC style hearing aids by Starkey and the hassle-free invisible Lyric hearing aids for our selective patients who value discretion and ease of use. We have many patients who are top officials, lawyers, tech moguls, actors, musicians, doctors, and diplomats who prefer these types of devices. The Lyric, as an example, is like a contact lens for the ear requiring virtually no maintenance and no batteries to change or charge.


Please don’t get the wrong idea, though; we do not only see the rich and famous; we have patients from all walks of life, ages, and races. If you are ready to take your hearing to the next level, we can help. Also, if you already have hearing aids from somewhere else and need assistance, we can optimize them to help you hear better.


We treat patients the way they should be treated – with kindness, expertise, and exceptional follow-up care. In our region, discerning patients expect to see highly credentialed providers for their hearing and balance care. This is why both physicians and patients trust our practice. We have a supervising audiologist at every location and accept all major insurance plans for a full range of diagnostic and retail services and products. We have excellent relationships with local universities and prestigious hospitals, including Johns Hopkins, the University of Maryland, and Georgetown University. We are among the very few clinics in the country with two rotary chairs for advanced balance evaluations. We help children and adults with their hearing and balance, and we are the practice of choice for Universities to send their interns for training as well.

For these reasons, as well as the reputation of many of our providers, we hope that you will trust us to provide you with the very best hearing and balance care. We look forward to your visit.

Hearing Test

Hearing Tests

Did you know the average person lives with hearing loss for seven years before they seek help? Imagine all the sounds you miss in seven years. Don’t miss a moment of the soundtrack of your life. Start with a complete audiological evaluation at one of our convenient locations to assess your ability to hear and process sounds. A hearing test is the first step in identifying and treating your hearing needs. It involves a painless process that is noninvasive and conducted by our expert audiologist.

An audiological evaluation measures your hearing capacity in both ears which identifies any impairment and the degree of hearing loss you could be experiencing. Once we have this information, we can recommend the treatment options that will best meet your needs and enhance your hearing health.

Hearing Aid Fitting

Hearing Aid Fitting

The next step after completing the hearing test is selecting and fitting the hearing aid device that will maximize your hearing. We use our expertise, extensive experience, and knowledge of the latest hearing aid technology to recommend the device that will be optimal for you. Depending on the specific hearing aid you choose, we will take molds of your ear to customize the hearing aid pieces to fit you perfectly.

During your fitting appointment, your audiologist will program the settings on your device to meet your specific hearing loss needs. We will then thoroughly discuss your device with you - going through how to maximize its use, the features, and settings available to you, how to effectively maintain the device, and how to properly insert and remove it. We want to ensure that you are as comfortable and knowledgeable about your new device as possible!

Hearing Aid Repair

Hearing Aid Repair

At Audiology and Hearing Aid Center, we also provide in-house hearing aid repair services. This offers convenience when your hearing aids need a quick fix. Hearing aids are durable devices that last 5 to 7 years. But like all devices, they can be impacted by daily wear and tear. Exposure to moisture, dirt and other natural debris that can build up in the ears can also accumulate on hearing aid devices. This can cause damages to the hardware which requires repair. In addition to fixing the microphone, common repairs include: replacing earpieces, replacing the tube that connects behind the ear hearing aids to pieces worn in the ear, and fixing the door that locks in the battery. We aim to efficiently conduct hearing aid repairs so that your device is working optimally.

Hearing Protection

Hearing Protection

In addition to treating hearing loss, we are invested in protecting hearing health from further harm. One way we do this is by making custom hearing protection. Wearing hearing protection is an effective way to reduce exposure to loud noise. Absorbing noise not only is a major cause of hearing loss but can also heighten hearing loss symptoms like tinnitus. According to the Hearing Loss Association of America, 22 million people are exposed to hazardous levels of noise in the workplace.

Additionally, the World Health Organization estimates that over 1 billion people globally are currently at a higher risk of developing hearing loss due to loud noise exposure. This highlights the importance of protecting hearing health and hearing protection is a key way to do that. Our practice makes individualized earplugs by taking custom molds of your ear. This ensures a perfect fit in your ear canals and this protective wear offers a barrier that reduces the impact of loud noise.

Tinnitus Treatment

Tinnitus Treatment

Ringing, chirping, whirring, or buzzing. Tinnitus noise isn’t the same for every person. When you hear sounds that aren’t present in your environment, it’s a symptom called tinnitus. The process of hearing is a complex interaction between the many parts of your ear and your brain. When things get out of sync, tinnitus can result. Consult the tinnitus experts at Audiology and Hearing Aid Center to diagnose the cause of your tinnitus.

People often say “I don't have time to write reviews”, but I couldn’t pass up the opportunity to help others by sharing my mother’s WONDERFUL experience with Dr. Marisa Fassnacht, an extremely knowledgeable, compassionate and upbeat audiologist. Dr. Marisa truly cared about helping my mom, who previously had been to several audiologists but never trusted them. My mom has been having trouble with her hearing aids which didn’t seem to be helping much lately. Dr. Marisa demonstrated the utmost patience by listening to all of my mom’s questions and concerns and thoroughly answering each one of them. After making the necessary adjustments to her hearing aids, Dr. Marisa provided practical tips on how my mom could communicate and interact with people to slowly build up her confidence. My mom recently told me that she feels she is gaining her life back, hearing loved ones and becoming a more active participant in conversations. I wholeheartedly recommend Dr. Marisa, and the entire exceptional team at the Audiology and Hearing Aid Center. My mom will definitely be seeing Dr. Marisa again when she is ready for her next set of hearing aids, as she has finally found an audiologist she trusts!

In my opinion there is no firm better to diagnose and care for your hearing issues than Dr Holi Lish and her staff at AHAC. I am a perfectionist and demand great customer service. I get that and more with Dr Lish and her staff. The process of just getting hearing aides and learning to use them properly is a daunting experience in itself - you just naturally feel old. The process used at AHAC takes all the anxiety and stress out of the hearing aide purchase and the proper use of the equipment. Contact DR Lish and you will see what I mean.

What a journey and a joy it has been rediscovering sound after getting hearing aids from Audiology & Hearing Aid Center in Warminster, PA. I knew I had hearing loss but didn’t realize how just bad it is, and I’ve had nothing but delightful times getting used to being able to hear again. To carry on conversations with my friends again in public or private, inside or out, even in the phone, and be able to actually understand what they’re saying. To not be exhausted after speaking with somebody for a while because I’m putting so much effort into trying to understand them, and still getting it wrong much of the time. To be able to speak with children again, and clearly hear their higher pitched voices. To hear just how many birds are really singing and chattering around me, and hear the fullness of the stream in my favorite park. To be able to hear my own voice again… I find myself singing around the house again because I no longer sound off key to myself. I discovered just last night that someone I’ve met in the last year has an accent; I’ve never heard it before because I was only hearing part of his voice. And while brushing my teeth is best done with my hearing aids out 😁, pretty much everything else is best done with them in. I also find I’m more aware of sound even when I’m not wearing them, I think because my brain has been ignoring what it could not interpret, and now is conscious of it again. Sound has been brought back more fully into my world, and I’m so enjoying getting used to it. If you think you have a hearing problem, get it checked out, because you may be missing more than you realize. This practice is a wonderful group of folks who take the time to explain it all, make sure it works for you, and help you get the best experience you can from your hearing aids.

I recently got my second pair of hearing aids from Dr. Lish and the team at AHAC. I was so happy with my previous pair, until they started deteriorating. Dr. Lish cleaned and tested them, and informed me they were on their way out. I now have a new pair (of Phonak ones this time) and I could not be happier with how well they work. I am so grateful to Dr. Lish for her help and advice - and always seeing her smile (you can even see it through her very cool mask now). Delighted seems a fitting word for my experience with AHAC; I wouldn't consider going anywhere else for my hearing needs.

I have been wearing hearing aids since I was 49 yrs old, am now 69 yrs old, and thrilled to be wearing the newest rechargeable battery hearing aids. No messing around with keeping batteries in my pocket or purse or needing to change them at the most inappropriate moment. Plug them in at night before going to sleep, unplug and place in my ears first thing in the morning, and done. At AHAC, my audiologist, Holly, is always up to date with the latest in hearing aid improvements. Holly takes the time to explain patiently how any of the devices work and wisely schedules check-up appts for the devices. AHAC is the best hearing aid center I have been with.

After several pair of hearing aids and audiologists over the last 7 years, I finally found an audiologist who is fantastic! Dr. Maryann Nikander is a hearing impaired individuals dream! Starting from the initial hearing test, to the actual hearing aid determination, to the first fitting, EVERYTHING was accomplished in accordance with “best hearing practices.” I had a pair of custom ear pieces made by Dr. Nikander and they are perfect! No more annoying feedback noises or stuck domes in the ear canal! During the first fitting, she spent 2 hours with me fine tuning the hearing aids and explaining everything in detail! After two weeks, during my first post visit, we discussed what I liked and disliked about the aids and made adjustments. She even called the hearing aid manufacturer to ask about a question I had brought up! At every step in the process she thoroughly explained what she was doing and made sure that all my questions and concerns were addressed before I left. I never feel rushed and I am able to get every question answered. My hearing has never been better! I can actually hear sounds that just a few months ago I thought were gone forever! I watch the you tube channel and follow Dr. Cliff. He is a wealth of knowledge on hearing and hearing aids. Dr. Nikander was listed on his site as a qualified audiologist, with many years of experience who he determined follows Best practices. I highly recommend her when you require hearing and hearing aid expertise.

I was very fortunate to have my brother refer me to the Audiology and Hearing Aid Center in Warminster, PA and, in particular, Dr. Holli Lish. My brother called his hearing aids a "game changer" and how right he was. He told me that Dr. Lish would be most professional yet caring, helpful with the latest knowledge and offer me a simple way to understand the complex issues of adapting to hearing aids. Dr. Lish was all of that PLUS. When I had some initial problems adjusting the newly prescribed aids, she provided technical support in a very friendly manner. Dr. Lish has the most pleasing disposition in dealing with me because she comes across more as a 'friend with knowledge' than an overbearing 'know-it-all'. I would not hesitate to recommend Dr. Lish, or for that the whole staff at the Audiology and Hearing Aid Center in Warminster, PA, for any audiology needs.

I found Audiology and Hearing Aid Center in Warminster in a directory of audiologists that follow best practices. Dr. Holli Lish did an excellent job of understanding my specific needs and selecting and fitting the hearing aids best suited to my situation. Hearing aids are a significant investment in quality of life, so it is important that they are programmed and fitted correctly. I feel confident that my hearing aids are working at their absolute best, and I am hearing things I haven't heard in years. Highly recommended!

For years I struggled with a decreased level of hearing in parallel with an increased level of Tinnitus. As I look back, I now realize that I negated these occurrences; didn't want to admit it. It took a toll in regard to career performance and general life satisfaction. My mind was filling in the blanks and drawing inaccurate conclusions of what people were saying. Since being fitted up properly with hearing aids by Maryann at the Audiology and Hearing Center in 2019 my life has changed! I no longer fill in those blanks of what others are saying and my communication skills (both listening and speaking) have improved exponentially; especially in this day of age where communication is vital at both home and the office. The improved ability to hear really does support quality of life along with having a positive mindset. Maryann and her team at the Audiology and Hearing Aid Center are top notch professionals. For an end note, I have included the image below, because at age 55 vinyl records have never sounded better!
