Dr Khullar is an amazing Dr. I have had surgery for lung cancer by him and he speaks to me and explains everything thoroughly. He's incredibly smart and stays up to date on the latest for his patients. I can tell he truly cares and wants to make a difference in my life and the lives of his patients. He waits to make sure all my questions are answered. He is a great Dr.
