“I called for an appointment and was able to get in without waiting a considerable about of time. I was greeted by an efficient and relaxed atmosphere. Dr. Sondra gave an efficient exam and I was impressed with how she took the time and patience to explain how the hearing aids work and how to care for them. She made me feel like I didn’t need to worry about if the hearing aids would help me, because she would make sure I was satisfied with how I was hearing. Thank you Dr. Sondra for the confidence!”

“I have struggled with hearing loss for many years and kept putting it off to get help. During this time I knew I was missing out in conversations and would eventually withdraw completely. After being urged enough by family and friends I decided it was time to get hearing aids. I was encouraged by family to go to Dr. Sondra Rierson at Adaptive Audiology Solutions. I called and set up an appointment. Dr. Rierson and her staff are very pleasant, friendly, and knowledgeable. They truly want to make a difference in helping you hear again. I am very thankful to Dr. Rierson and her staff. It’s wonderful to hear again and get part of my life back.”

- Wayne Heithoff

“I got my Cochlear implant 10 years ago in Omaha, NE. I always had a family member drive me to Omaha as I didn’t like driving in the city. So, this year I checked with Cochlear to see if there was an audiologist closest to where I live. And they said there was one in Carroll, IA. So, I got on the phone and made an appointment. I am now going to Sondra. I’m going to Denison where she has an office. She has been very helpful to me. I am very comfortable working with her. She goes the extra mile to solve problems I may have. She is friendly and a good listener.”

“My situation with having a hearing disability stems from many years. Not having a reliable hearing doctor left me in distress. Finding Sondra has been a God send!  Having had a mastoid surgery at age two, I have had many troubles with drainage and hearing loss. Then, I came to know Sondra and got hearing aids. I’m able to get along better than I ever could. Meeting Sondra in 2010, I met “my angel in disguise.”

- Madonna Schreck

“I am finding that part of growing old is missing out on fun times with the gals and not hearing what everyone is laughing at. I for one never want to miss a good joke. Years go fast. I find smiling and laughing make a huge difference in my day. Sad that my dad did not have a chance to better his hearing as I did. Little did I know how loud I had to have the radio on. Thankful to the help I found from Sondra and her girls. Family and friends in my life are so much happier and are finding out I’m a normal 88-year-old grandma.”

- Joan Badding

“Dr. Rierson and her staff are very knowledgeable and professional. At the same time, they are patient, friendly and kind.

- Bob Cogdill

“I can’t begin to tell you how happy I am to have Dr Rierson back in Carroll as when I have a problem with my hearing aids all I have to do is call her office and she sees me as soon as she can. I changed insurance because it allowed me to get hearing aids for free, but I had to travel 30 miles away and did not like the hearing aids or the service. Long story short I went back to Dr. Sondra and paid for new ones. I have never been sorry to do that-the hearing aids I got from her are the answer I was looking for. I am very satisfied with the special care that Dr. Sondra and Adaptive Audiology Solutions gives me for my hearing healthcare needs. We are fortunate to have her right here in Carroll.”

- LaVonne Knauss

She answered all the questions I had in terms I could understand. With each office visit she has taken time to always address my concerns. It is a blessing to have her helping me throughout the process of adjusting to the implant. Having her and her patient care coordinator, Susie, to assist me has been wonderful. I wouldn’t hesitate to encourage anyone to give her a call.”

Dr. Sondra has taken so much time with working on improving my hearing. I am just amazed at the time it takes to get used to hearing all the sounds that I wasn’t hearing before. I am so thankful. Not having to say “what” all the time is wonderful. I love my hearing aids and I cannot live without them! Thank you Dr. Sondra.”

Sondra worked with another company when I first met her and I found her very knowledgeable and caring about hearing loss.

She has all the necessary equipment to test hearing to prescribe the best outcome. I have complete confidence in her and would recommend her to anyone with hearing problems.”

- Barbara Fritz

“I have been noticing my hearing has been getting worse over time, especially my left ear. At work, I have a yearly hearing test, and this past year the nurse suggested I should have it checked further by a professional. I chose to go to Sondra Rierson. She was very knowledgeable, helpful and explained everything to me that I asked. From her testing she told me I likely had otosclerosis, which is a bone growth in my middle ear. Sondra suggested surgery, which I was hesitant about at first, but went ahead with it. My left ear can now hear better than my right ear! Thanks to Sondra for her knowledge and also pointing the way to a great surgeon.”

- Nancy Bowman

“I really enjoyed meeting and working with Adaptive Audiology Solutions. From start to finish, Susie and Sondra listened to my concerns and my needs, and fitted me with the best hearing aids for me.

- Roger Kanne

“I put off a visit to an audiologist for some time even though I could tell that my hearing was not what it used to be . My children were after me to have my hearing checked. I finally gave in and went to Adaptive Audiology for a hearing test. I wanted to stay local and a friend recommended that I see Dr. Rierson. I am so happy that I went. After the hearing test and seeing the results I realized that my hearing was failing. After I got my hearing aids, I noticed two thing right away-I could turn the TV volume down and I could hear the birds sing. The hearing test, getting the hearing aids and above all else, the excellent service that you get from Dr. Rierson is just great. I’m so glad that I made the decision to improve my hearing.”

- Jim Ulveling

“Realizing that my hearing was becoming a problem with conversations with family and friends, I opted to seek audiology assistance. My decision to use the services of Adaptive Audiology and Dr. Sondra Rierson was clearly the right choice!

She was professional and extremely knowledgeable in every aspect of making sure I got the right fit and the right type of hearing aids. She welcomed any questions I had and made sure I was comfortable and informed about the care and use of my particular aids. The price was much lower than I expected.

Dr. Sondra and Susie make a great pair and it is always a pleasant experience when I go to their office.”

- Jeff McCool

“When I realized I was missing out on conversations, struggling with hearing at work and on the phone, I contacted Sondra Rierson at the recommendations of family and friends. I have been so pleased with Sondra and her staff. Sondra was very thorough and explained everything to me and was always great at answering any questions when I come in for a routine check. She fitted me with what I needed. Getting hearing aids from Adaptive Audiology and Sondra Rierson was a great decision. Never regretted it!”

- Della Lappe

“My first appointment with Dr. Rierson was purely to prove to my friends that there was nothing wrong with my hearing! Well to my surprise when Dr. Rierson showed me the results of my hearing test, it showed I had a 30% hearing loss in both ears. That was a fact I had to come to terms with and Dr. Rierson did not pressure me to get hearing aids.  She simply told me that my hearing loss would get worse over time and that if I decided to get aids, my hearing could be back to almost 100%. It only took me about a week to decide that I didn’t want to live the rest of my life asking people to repeat what they had said to me or pretending I understood something that was said when I really didn’t. From my first meeting with Dr. Rierson to the present I have felt comfortable with her and enjoy my relationship with her. She is very knowledgeable in a caring way. Susie, her receptionist is very welcoming and thorough also! She and Dr. compliment each other well. I would definitely recommend Dr. Rierson to anyone who is experiencing hearing loss.”

- Linda Steinkamp

“Gary and I wish to express our thank you to Sondra for opening Adaptive Audiology Solutions. Without her, it just wasn’t the same.

Just lately, Sondra and Susie fought to get his hearing aids fixed right. It is great when Gary can hear! Thanks again.”

- Gary and Deb Keesling

- Duane Greving

“As an elderly patient it’s difficult to admit to needing hearing aids. You made the decision very easy; would recommend your office to all. The help received was superb, and the adjustment to the aids is easy, especially with all the help from you and knowing I can come back with any problems. The hearing aids are almost invisible and the family thanks you too, as I don’t blast them with the volume on the tv! Thank you so much.”

- Deon Rowedder

“I knew from my husband’s experience that wearing properly adjusted hearing aids is a different story than getting corrective eyeglasses. Because of this [working] locally was an important factor for me. The hearing evaluation I received at Adaptive Audiology was by far the most comprehensive of the three I had prior to getting my hearing aids from Dr. Rierson. The follow-up regular appointments at my convenience has made my adjustment easier as well. The workshops and meetings her office offers have also been a plus.”

She took the time to show me what there was to improve my hearing and what would work best for me. I can now enjoy and participate more with friends and family. Thank you for everything.”

- Mike Mielk

- Clay Winterboer

“I tell everybody that Sondra is an amazing audiologist.  She is great at explaining things to me, so that I understand them.  When she first started working with me, she told me I would be wasting my money amplifying my right ear, which is completely deaf.  She could have sold me a hearing aid, but she was honest with me and put my needs first.  She always takes care of what I need and she goes the extra mile.  She is very professional and reliable.  I love to promote Dr. Rierson and her services to everyone I know!”

- Jeff Sebring

“I have been to three other hearing establishments-two in Carroll and one in Ames.  I heard Dr. Rierson’s ad on the radio and decided to give it a try.  At the other place I went to I was treated like an old lady and I felt like I meant nothing. With Dr. Rierson, you are a person-your hearing matters and you matter!  She adjusted my hearing aids and sent one in.  I hear better now than the last five years.  TV is a lot better! Thanks Dr. Rierson!”

- Donna Ankenbauer

“I was visiting my daughter at Auburn.  I am wearing hearing aids, but I was asking “what?” a lot. She took me to Dr. Rierson at Adaptive Audiology. She checked my ears for hearing and for wax.  She gave my hearing aids a good cleaning and adjusted the settings.  My hearing is much better, and I will go back in six months to have them checked again.  I am one happy 98 year old lady thanks to Dr. Rierson.”

- Bertha Wagner
