What Patients are Saying

  • “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 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”

  • “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.”

  • “ 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, 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!
    Jerry Hodson”

  • “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.”

  • “ 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!!”

  • “ 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.”
