What Patients are Saying

  • 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 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.”

  • “ 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.”
