"Thank you, I am doing fantastic with my new sound system!  I have never experienced this amazing sound quality in all these years.  I now get to listen to music and hear vocal and instrumental sounds that bring me pleasure instead of irritation.  I don't shy away from conversations now and love hearing the bird melodies.  Your dedication has literally changed my life and opened a different world for me.  I am so grateful."

"My experience with Dr. Cody has been nothing but top notch.  The office is located in a very nice neighborhood with plenty of street and residential parking, so that was reassuring.  The office is very clean and comfortable as well.  Her examination and explanations were comprehensive.  She made sure that my current hearing aids were functioning properly, changed the filters even though I did not purchase them there, and reviewed the settings on the device.  Most importantly, I never felt rushed.  I had ample time to complete the necessary series of evaluations.  Dr. Cody exhibited the right blend of professionalism, inquiries, and empathy to make me feel confident that things were being done right.  I can say confidently that I have a greater appreciation for not only what hearing assist devices can do, but also understand that the right audiologist is necessary to achieve my best performance in aided hearing.  Dr. Cody certainly does that and is an advocate for my interests.  Thank you for giving me the best attention!

"I just showed up here unannounced while on vacation because I had a hearing aid emergency.  Donna took me right in and immediately treated me like her own patient.  She ordered the part of my hearing aid for me that had broken.  I came in on a Friday and the part would arrive that Monday.  She charged me nothing other than the shipping to get the part there by Monday.  So grateful.  My vacation would have been ruined if I couldn't hear out of one ear."

"Dr. Cody is amazing!  I have gone to her for hearing tests for about 18 months now. Today, I had an urgent ear condition and she got me in immediately and took care of it!  She explains test results and ear conditions clearly and concisely.  It is without hesitation that I recommend Dr. Cody!  When I need a hearing device, she will be the one I consult."

"Dr. Cody is the consummate professional, patient, kind, caring and very knowledgeable.  You don't feel rushed and she will stay with you as long as you have questions.  While the Hearing Aid Industry is often accused of overselling whether you need hearing aids or not, this will not happen with Dr. Cody.  She wants what is best for you not for her pocket book.  Look no further.  You've found the best."

"I have worn hearing aids for over ten years now and have never experienced the vast improvements that you, through your expertise, have given to me.  I really didn't think that it was possible to hear so well again, nor did I realize how difficult it was for people to talk to me..."


Newport Beach, CA

"Best in the business.  Don't go anywhere else.  Dr. Donna is focused on your satisfaction.  My dad came over from England and Donna sorted out new hearing aids for him and continued to follow up with regular e-mails and phone calls.  Absolutely unbelievable customer service."

"I wanted to call and let you know that I love my hearing aids.  I spent almost a week in Las Vegas.  We had a baptism and a first communion, and they (the hearing aids) were wonderful.  Thank you very much for all of your help and all of your patience.  I'm very happy."

"Dr. Donna Cody has helped me hear well again.  She is very nice and extremely thorough.  She ran extensive tests and identified where I was having trouble, and she made sure that I was comfortable with my options.  She allowed me to test different hearing aids to determine which one worked best for me.  I am very happy with the hearing aid that I finally ordered as it has really helped me.  Dr. Cody follows up frequently to be sure that everything is okay, and is very willing to make adjustments if they are necessary.  Dr. Cody has a lot of experience in the field and worked at the House Institute of over a decade, so she has really good training.  I am very happy with Dr. Cody, and so is my family since I can hear them again"

"Doctor Cody had to perform a hearing in noise test (HINT) on me due to my change in careers.  I was recommended by the County to see Doctor Cody.  Walking into their establishment, I felt very comfortable.  I was greeted by her staff who was very accommodating.  I really enjoyed talking to her staff before the test while completing the paperwork.  Doctor Cody took the time to conduct many tests for me and she was honest and fair.  I highly recommend the Coast Hearing and Balance Center.  Thank you, Doctor Donna for being so professional, honest, and caring."

"Over the past 15 years I have gone to 5 audiologists.  All were competent but none except Donna displayed any concern regarding my time and expense.  Often they made adjustments to my hearing aid and told me to come back if the adjustment didn't improve my hearing, as if that's all I had to do with my time.  Donna shows a personal interest in me and follows up on her work.  While she is busy, you do not get the impression that you are one of the crowd being processed that day.  Expect care and attention above the norm when you visit her."

"I have been very fortunate in seeking help from Dr. Cody.  She has provided the care and advice which have enabled me to obtain satisfaction with hearing devices for the first time in many years of seeking that help from other professions.  She is a treasure."

"I had a serious hearing loss in my left ear since childhood.  The loss was caused by otosclerosis.  As I grew older (I am now 80), the loss accelerated, and I now also suffer hearing loss in my right ear.  I consulted several hearing loss specialists, but they could not correct the problem or fit me with hearing aids that significantly improved my hearing.  Upon the recommendation of a family member, I decided to seek advice from Dr. Donna Cody at Coast Hearing and Balance Center in Corona del Mar.  What has impressed me the most about Dr. Cody is her sincere desire to help me improve my hearing.  Over a period of several months, I visited her office multiple times as she tried different hearing aids and different settings in an effort to find hearing aids that work best for my condition.  She allowed me to test different hearing aids for weeks at a time and was always courteous and patient in listening to my assessments.  Most importantly, she refused to give up until she found a solution.  All of these visits were without charge.  In the end, Dr. Cody was able to fit me with hearings aids that significantly improved my hearing, as well as my quality of life.  If you have a hearing problem, don't make the same mistake I did by assuming you need to learn to live with the problem.  Technology is constantly improving and there are a lot of options for those of us who suffer from hearing loss.  Start by giving Dr. Cody a call."
