“The doctors and people there are really great. They are very friendly and seem to really care that people have been hurt, and they need that special attention to get better. These doctors and people are there to help!! A great experience all around. Thank you.”
“Dr. Cutler is amazing, he took the time to explain to me what is actually going on in my ears, nose and throat and why he recommends surgical procedures. He also took the time to answer all of my questions and ease my concerns with a great attitude.”
“Dr. Cote is fantastic!! I would highly recommend this practice. His professionalism and good nature keep me coming back. The front office staff are very friendly and are more than willing to answer any questions you may have regarding treatments and procedures.”
“I was very impressed with the amount of time the doctor spent with me and how knowledgeable he was. The assistant was also extremely nice and helpful.”
“Your staff was extremely friendly, courteous, helpful, and knowledgeable.”
“Dr Varadarajan, is a life saver!
He and his team removed an acoustic neuroma tumor from my left ear leaving the facial nerve intact. He personally came to see my every day I was in the hospital to check on me and the hospital staff took care of my daily needs in the hospital and refill medications as needed without delay.
I could not ask for better health care than that of Dr Varadarajan!
“ I had a cochlear implant procedure on 1/18/2022.
Dr. Varadarajan and everyone at AOO has been exceptional. I am so glad I found this office for my hearing needs. Dr Varadarajan takes the time to explain everything in a way I can understand. He puts the patient first, has excellent bedside manners and is passionate about his profession
If you need to be seen for hearing issues I highly recommend AOO”
“ Dr. V and the staff here could not have been more incredible. The time and care they gave throughout my visits have consistently left me absolutely comforted and assured. Dr. V’s expertise as a surgeon brought me back from severe hearing loss in my left ear to a whopping 92% gain! I am grateful to my core for the gift that he and the staff have given to me. 18/10, and would give all the stars if I could.”
“ Dr. Varadarajan has to be one of the best Doctors I’ve worked with, period. He has been in constant contact with me throughout this process and even fought my insurance for over an hour to ensure approval for a much needed cochlear implant. In the day of rushing patients in one door / out the other he always answered my every question and then some never once making me feel rushed. The surgery was, completely text book, according to his nerve monitoring teams calculations. Top notch surgeon, couldn’t be happier with him!!”
“I would suggest going to Associates of Otolaryngology for any loss of hearing. Dr Varun Varadarajan was incredibly wonderful. I couldn’t hear out of my left ear for over 6 months due to a motor vehicle accident with constant ringing coming from the ear. 2 bones in my ear were broken and had to be replaced with titanium prosthetics. Dr Varadarajan was able to get me into surgery very quickly. Due to my car accident I received a brain injury as well as my loss of hearing and Dr Varadarajan was able to explain what could possibly be wrong in my ear so I could understand. Dr Varadarajan was very funny, helpful, and so so so much more along with the entire practice. As of today it has been a week since my surgery and my hearing in the ear is returning. I owe everything to Dr Varadarajan. I could not be happier with my treatment and experience with Associates of Otolaryngology and Dr Varun Varadarajan.”
“I am an audiologist who collaborates with Dr. Varun Varadarajan on a regular basis. I have the upmost trust in sending my patients to him when further medical evaluation/intervention is needed (e.g., implantable devices such as cochlear implants or bone conduction implants, conductive or sudden hearing loss, acoustic neuroma, dizziness/vertigo, etc.). Dr. Varun Varadarajan always treats my patients with kindness, values their time and validates their concerns… this is important to me when considering where to send my patients for additional care. Beyond his bedside manner, his examinations are thorough with great attention to detail. He takes the time to educate his patients on his recommendations and creates confidence surrounding any follow up care that may be needed. If you are in need of an otologist, I highly recommend Dr. Varadarajan as I trust him with my own patients and would recommend him to family/friends as well.”
“I had an amazing experience with Dr. Varadarajan at Associates of Otolaryngology. I had a minimally invasive tympanoplasty that healed perfectly with very little post operative discomfort. Dr. Varadarajan and the office staff are wonderful. I would recommend Dr. Varadarajan with all your ENT concerns.”
“ As an audiologist, I have worked with many ENT physicians over the years. Dr. Varun Varadarajan is by far the best provider I have had the privilege to work with. He takes the time to ensure each patient not only has an appropriate treatment plan but also a good understanding of any medical diagnosis or recommendation. Dr. Varadarajan shows he is consistently focused on providing patients with excellent care. I feel extremely confident in sending my patients to him and would trust him with my own family members.”
Dr Cosgriff was wonderful, very professional, knowledgeable and helped a lot. I was having problems with ear wax in my very small ear canals, and I went to a unrelated clinic first to get it removed. They only made it worse, and actually cut my ear canal, I couldn’t hear from the blocked wax, then suggested I go to an ENT. I was able to get a quick appointment with Dr Cosgriff, and with her special tools, and her expertise, she was able to fix my ears right away. What a difference! I found her office on yelp with all the positive reviews! Thank goodness!
Dr Monica really listened and provided procedures / medicines that resolved sinus and throat problems I had been dealing with for a long time.
They are friendly reception and the Dr. Was amazing. Definitely recommend.
So far this service is great and we’ll see going forward with my appointments.
Expedient, courteous and professional.
I was very impressed with the thorough diagnostic exam that I received from Dr. Cosgriff and her assistants. I felt that they all listened to my concerns and answered my questions, as well as suggesting that I receive some physical therapy, which I will do to help alleviate the vertigo I am experiencing.I would recommend Dr. Cosgriff to friends and family!
Dr. Jeffrey Cutler is terrific. I have had chronic sinusitis for years. Dr. Cutler has mapped out strategies and procedures to mitigate the frequency of my sinusitis episodes. He is personable, relatable, and takes the time to question and completely understand your current situation. He uses diagnostic tools, your history & physical examination to estblish a differential diagnosis and then discusses treatment options with you NOT to you. He is top notch.
I had a severely obstructive scar tissue band removed from my right nasal cavity as well as a turbinate reduction. My surgery with Dr. Rasband was 1 month ago and I am LOVING the outcome! Just a few days after surgery, I was breathing 100% better. Dr. Rasband provided me with some cool pictures of the surgery. Recovery was quite easy, I was actually able to attend a work meeting the next day in office. I saw her a few times since then for post-op appointments. No re-adherence of the scar tissue band, and I am breathing 100% better. It’s amazing to have both sides of my nose open!
Very professional treatment and analysis!
Dr Swartz and his team were prompt, helpful, enthusiastic and empathetic. Best doctor experience I’ve had in a long time! Highly recommended.
Dr. Varadarjan is a wonderful Otologist! He specializes in all ear related problems. He works with all Cochlear Implant manufacturers and is a surgeon I would trust for myself or any of my family members. He offers many surgical options for hearing rehabilitation including eardrum reconstruction, ossicular chain reconstruction, bone conduction implants, and more.
Office runs great, staff helpful, Dr. Varadarajan did an excellent job on my surgery and follow up.
I recently had to find a new ENT after my employer changed my insurance. I have a complicated health history so it can be daunting to find a new provider that you trust. I was very pleased with Dr. Picerno – she was kind, patient and very thorough! I’m so happy to have found her! I also met with Amelia, an audiologist, and she was also awesome!
I have been dealing with extremely weird problems with my right ear for about two and a half months. After being ignored at my regular physicians office, I decided to see Dr. Schwartz ( Swartz) and I am so happy I did. The hearing test was thorough and I received the results immediately after which gave me relief. The assistant was so nice and made me feel like she was truly listening to me. I loved how she relayed everything to the doctor before he came in. Because of this, He gave me answers and set up a game plan immediately. I have never felt so taken care of! I truly felt important and heard. Thank you everyone in the office for being so amazing!
Great staff. Got me in right away. Dr. Griffin is great.
Going for a health test can be daunting, but they were great! All the way through my test I was made to be as comfortable as possible. -Kirk Bremer
I’ve been a patient at this clinic for years for sinus infections, sinus surgery, immunotherapy and hearing aids. I have always appreciated the care I’ve received. I particularly like Dr. J. Cutler, but am also comfortable seeing other doctors when he isn’t available. Both the Denver and the Lone Tree offices are easily accessible and have good parking. I’ve always been able to get an appointment when I needed to see a doctor, and the care of the allergy staff has been on point. Wait times have always been very acceptable. -Mary W.
Had a great experience with Dr Cote and great results! Would recommend Dr Cote. I would also go back for anything else I may need! -Cheryl B.
Ray FurlongI was referred to Dr. Varadarajan due to experiencing vertigo symptoms anytime I had pressure on my right ear (sneezing, coughing, laughing, bending over). These symptoms made it to where I could not drive or do many normal activities I am used too. After several tests and discussions with Dr. Varadarajan it was determined I may have a Perilymph Fistula. I elected for surgery and happy to say it was a success and I am vertigo free and able to do all activities! I appreciate Dr. Varadarajan for taking the time to understand my symptoms and go through the proper process/tests to diagnose my condition! – Ray Furlong
Dr. Schwartz is very kind and takes his time with patients. I appreciate his consultative approach. – Alison F.
Dr. Rasbband was delightful and made me feel like I was in good hands. There was a mixup with my appointment but they recovered nicely. Great experience.- Frank Barth…
When I first met Dr. Varadarajan, he made me feel so at ease with my decision to get a Cochlear Implant. He answered all of my questions and took time to be sure I felt comfortable moving forward. The first surgery on my left ear was a success! Healing and recovery were far better than I expected. I will have my right ear surgery next week. He has been there with me through the entire process. I trust him completely and have found a whole new world of hearing that I never thought possible. I highly recommend Dr. V to anyone who is struggling with hearing loss and doesn’t fully understand the process of Cochlear Implants. He is the best!
I 100% recommend Dr. V, he has listened to all my concerns and went the extra mile to make sure that my tinnitus is nothing life threatening. So grateful for a doctor that truly cares about his patients! -Desiree Worsencroft
Always able to get an appointment, front desk friendly and efficient. Shout out to Kyle an assistant to Dr. Cutler. He was caring and easy to talk too. Dr. Cutler is a very skilled surgeon with impressive credentials. He was reassuring with my sinus issues and monitoring my progress since my surgery in May. Dr. Cutler is realistic about my condition but helps me stay on a manageable program for my sinus condition. Many good reasons to continue my care at AOO!
Erin was so great in my appointment she was very informative and gave me great info. She gets 5 stars from me
