I recently visited the Koala Center for Sleep Disorders and TMJ to address my symptoms of jaw popping, tinnitus, and headaches. As an international student, I was initially apprehensive about navigating my symptoms in an unfamiliar environment. However, Dr. Gray and his team provided exceptional support and care, easing my concerns and providing me with a sense of reassurance. Dr. Gray's thorough and comprehensive approach to diagnosis and treatment is unparalleled. During my initial consultation, he took the time to explain the root cause of my symptoms and how they were affecting me. Based on his expert evaluation, he recommended an oral appliance treatment plan, which included a daytime orthotic and night guard. I was impressed with the swift action taken by his team to create and prepare my oral appliances for my treatment. Furthermore, Dr. Gray's dedication to his patients is evident in his consistent monitoring of my progress. He has been seeing me weekly to assess the status of my improvement, and his team has been highly responsive and always willing to help with any queries or concerns. I highly recommend the Koala Center for Sleep Disorders and TMJ and Dr. Gray for anyone seeking specialized care in these areas. Dr. Gray's extensive knowledge, exceptional care, and commitment to his patients' wellbeing make him a standout practitioner in the field. Thank you to Dr. Gray and his team for their unwavering support and outstanding service.

I had flunked my sleep study test and tried a CPAP for several months. The best part of the night with the CPAP was when I removed is a went right to sleep. Then I discovered Koala Center for Sleep. Dr. Gray fit me with a mouth piece that helps you breath better during the night and keeping your air passage open. I have had the device since Nov. 2018 and just took a sleep test and my numbers are wonderful. I now sleep all night and don't worry about all the complications of Sleep Apnia. Thank you Koala Center for Sleep. Life is good.
