    Nothing short of excellent rating for Dr. Khullar and his assistant Shannon. He instilled in me a confidence that he can and will deal w/any situation that may arise w/proposed surgery. Since my terrifying lung cancer diagnosis on 4/27/24, I finally felt calm and confident that I'll be taken care of by Dr. Khullar. And for this, I'm SO THANKFUL.
