Our team of Doctors of Audiology are committed to exceptional results through Best Practice care.
Our Doctors of Audiology work collaboratively to ensure that each and every patient seen in our clinic receives the best audiologic care possible by following Best Practices. In addition to providing excellent care to patients with common forms of hearing loss, our audiologists specialize in treating some of the most complex forms of hearing loss. However, Doctors Cliff Olson, Leslie Balderas, Rachael Cook, and Kelsey Beck also understand that the experience you have inside of our clinic is just as important as the care you receive. That’s why we always strive to give you 5-star service every single time you step foot into Applied Hearing Solutions. During your visits in our state-of-the-art clinic, you will never be rushed through your appointments as we work to solve your hearing difficulties. On average, we spend over twice the amount of time with our patients compared to standard hearing clinics.

I was recently interviewed on our local news to educate the public about the correlation between hearing loss and dementia.
Research shows that hearing loss is the leading modifiable risk factor for dementia, and treating it proactively is a powerful way to mitigate dementia risk later in life.

Did you know that diabetes could actually increase your risk of hearing loss?
In this video I explain:
✅ Why people with type 2 diabetes are up to 4 times more likely to have hearing loss
✅ How elevated blood sugar (A1C levels) can damage the inner ear
✅ Why diabetes-related hearing loss usually affects high frequencies, reducing speech clarity
✅ How inflammation, reduced blood flow, and metabolic stress can permanently damage the cochlea
✅ What you can do right now to protect your hearing if you’re diabetic or pre-diabetic
I also talk about why the length of time you’ve had diabetes matters, how hearing loss can contribute to tinnitus and auditory deprivation, and why early diagnosis and treatment are critical if you want the best possible outcome.

Hearing aids are smaller, more powerful, and more feature-rich than ever before.
But despite all of this progress, there’s still one simple thing holding hearing aids back:

I drive from East Mesa to see Dr. Olson. It's worth the drive because Dr. Olson truly works to get you not a good fit but a great fit. Watch his YouTube videos and you see that he does his homework. He's a one man shop but that's a benefit in getting personalized care. I've been to three audiologists this year and wasn't happy until I found Dr. Olson.
