    Dr. Shah is an excellent doctor. He has been my doctor for over 10 years. He is so knowledgeable and always takes time to listen to me and give me the best possible care. I suffered for years with my hypothyroidism until I found him. We have been able to successfully manage my hypothyroidism for the last 10 years!
