I was totally satisfied with my visit this year- my 5th! Friendly, helpful staff, who helped me make my decision to not have my appliance changed out for a new one. I was informed that my insurance carrier (Security Health) probably would not cover the cost at the same percentage as 5 years ago. I will contact them! Thanks for everything!

the team at Koala Wausau's office are professional, informative, and patient. Delany will try to accommodate the situation when calling for an unscheduled appointment. Brenda has helped me many times in adjustment of appliance and spending time to make sure it it properly fit. thank you

Everything went very well! I arrived early because I wasn't sure about road construction. Koala staff got me in/out early, which was very nice as I have a 2+ hr. drive each way. Thank you! All staff members are very cordial & professional.

I can’t believe I am reviewing a place where I get my TMD device, but here I am. I have to say, I’ve always had the best experiences here. Specifically Delaney at the front desk is always so great with appointments and making changes if needed and she’s a very efficient worker! Also Sarah K, a treatment planner, is such a gem! She is working so hard on my pre-authorization and I feel she deserves a special shout out. Most places say ‘well you call your insurance, good luck’ but not her. She has went above and beyond. I have chewed through two devices from here so far (grinding is crazy) but the device does truly work amazingly for me when I wear it.

If you need an oral Appliance for sleep apnea this is the place to go! They know what they're doing and the communication and follow up is the best. No surprises here as they take care of all the details and make sure that you understand what is happening all along the way. From the front desk to the business office to the Hands-On care I had nothing but an exceptional experience

Great experience! The staffs were friendly, knowledgeable, and very professional. Dr. Willie was extremely knowledgeable about TMJ & Sleep Apnea & gave us detailed information about these disabilities and the newest treatment options available. Even though the current data on these disabilities & treatments are complicated, Dr Willie was able to explain them to us in a way we understood. We trust Dr. Willie, Koala Dental, and the treatments they offer. I would refer a friend or anyone, who needs these services, to the Koala Dental Clinic. Jill Wollenzien 06/2025.

Since I wasn't having any problems with the appliance, there really weren't any issues after the basic checkup was done.

1.1178082191781 year ago

Professional, felt comfortable with the whole process.

I went to Kolala Clinic on advice from my current dentist to check me for TMJ from his referral on my symptoms. I needed TMJ care. The doctor made me a splint, and I have worn it for 3 months and all the bad symptoms have subsided. He is about to tackle my sleep apnea problem. Dr. Willy and his staff are very professional and understanding. I would highly recommend them.

I find the Koala Sleep Center topnotch. I am a dental hygienist and highly recommend this clinic. Dr Wiley and his team are very professional,knowledgeable and friendly. I am so excited to use my new sleep apnea appliance! I want to thank all of you.

My spouse has been trying to get me to go and have a sleep study done for years. After meeting the Koala staff and how thorough every staff member was, I pulled the trigger and purchased the mouth pieces. They informed me when I started to dream again, the piece was doing its job. I now look forward every night to adjusting my mouth piece, intrigued to how my next morning is going to be. A week ago I had my first dream but couldn’t remember it, but I knew I had got some rest. Now, last night I had my second dream and this one lasted a while and I even remembered it when I woke up. Today makes the first day I truly got to witness first hand just how amazing this mouth piece is. I woke up knowing now what amazing rest can do for you over night. Something I haven’t felt in years. The best part about Koala and their knowledgeable team, when they reached out to see if I had any questions or concerns, she was excited at my excitement.. that’s why I chose to spend my money with them and currently trying to get my mother to go see them. I highly recommend going to Koala if you have or may believe you have sleeping problems. Thank you Dr. Brenda and the Koala team, you all have helped me start a new journey to better sleep AND better health. I’m only about 3 weeks into this, I can only have continued excitement knowing it’s only going to get better.

All staff were wonderful! I felt very well cared for. Would recommend highly!

1.9068493150685 year ago

Dr Willey is really awesome!! He knows exactly what is wrong & how to fix the problem!! Would totally recommend Koala to anyone!! He takes the time to thoroughly explain everything in great detail, & keeps working with the patient while the problem/issue is still unresolved, he doesn't just say well there's nothing more we can do for you, sorry, & send you on your way. He keeps working until the problem/issues is 💯 resolved. By far 1 of the greatest Dr's I've ever had the pleasure to be treated by!

Koala always treats their patients right! After I purchased my oral appliance, I have continued to receive excellent support from their staff. I highly recommend Koala. Optimizing your sleep will change your life.

Koala has been very patient with me. They have a great staff. I’m very happy with the care they have provided to me.

Staff was very accommodating & knowledgeable! We knew we were in the right place immediately and we were on the start of a great journey to fix what needed to be fixed.

For the first time, I felt someone was listening to me and actually offering solutions. Answers to questions like why I experienced ringing in my ears, and other odd sounds. Dr. Willy took the time to explain and show me the changes in my mouth, teeth spacing, jaw alignment and tongue are classic signs of TMD/TMJ. I look forward to being fit with an appliance that will help alleviate my sleep apnea and TMD symptoms, reducing stress points causing tension, pain and headaches. I would recommend others check this out.

Excellent device that improves sleep of sleep apnea patients. A terrific alternative to CPAP. Much more eco friendly and convenient. The staff are very friendly and knowledgeable. The arrived quickly and fits perfectly.

AMAZING! Night and day difference. Highly recommend if you have troubles with sleep apnea or TMJ or even snoring. The staff here are so friendly and ready to help take care of your needs. If I could add a million stars I would!! I recently got treated for TMJ and let me tell you, all of my symptoms were treated.

3.4794520547945 year ago

Staff is very kind and knowledgeable. They advocated for me with my insurance, who initially denied coverage, and got them to change their decision. I did not have to fight with insurance to get it covered, Koala did that for me.

I do not write a lot of reviews online. I had a moderately severe case of apnea. I was tired throughout most of the day. I woke up feeling groggy and clouded. One of the main factors that pushed me to get diagnosed and seek treatment finally is the toll it took on work, personal life, friends, etc.. the issue that kept me from doing something sooner was using a C-Pap machine. They are loud and hard to keep clean. I knew that I would not wear it consistently. My current provider had mentioned an appliance that was very similar to a retainer. Not as intrusive and is way easier to use. The whole setup at the clinic was painless, and the staff was very knowledgeable and friendly. They ensure you are comfortable using it and follow up a few weeks later to ensure everything is going well. I appreciated they took the initiative to do that. I also had the pleasure of talking to the Owner Dr.Willey, who is highly knowledgeable and genuinely cares about his patients. Companies these days sell you the product and send you on your way. Of course, it does take some getting used to and a few adjustments, which are easy to do. The point of this review is that Apnea is a severe issue that far too many people leave undiagnosed; most people underestimate what this can do for you and the people around you. On top of the fact that it can impact your health to a severe degree later in life. Hopefully, more people will become aware and take a little time to get an appliance like this or see a sleep professional. Thank you, everyone, at Koala
