Knowledgeable, caring, compassionate, the list goes on. Dr. Singh is heaven-sent. I have seen many specialists over the past 25 plus years and have been misdiagnosed for about the same length of time. My first visit with Dr. Singh, based off of my symptoms and really listening to me, he was already confident that he knew what was wrong with me. He ordered a test that was never recommended in the past by any of the other doctors, to confirm. Results are in and he hit the nail on the head! I am now looking forward to the treatment that is going to get me up and running again!
