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. |

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. |

I'm a big fan of Dr. Khullar - his interest seems to extend beyond having "something to cut" (some surgeons with whom I've interacted in the past only seemed interested to the extent that there's surgery to be done - I get the feeling from Dr. Khullar that he has an interest in the whole patient). I also appreciate the intellectual respect he offers - he doesn't talk down to me or presume that I might not understand the science behind his words and his work. I am fortunate to have landed in his care. |

Outstanding staff and hospital |
|

Both the assisting Dr. And Dr. khullar answered all my questions and concrns about my inability to swallow and covered next steps thoroughly. |
|

I did not like to mannerism of the female resident. She needs to keep in mind her audience meaning oncology. This area needs a little more compassion. Not "we done all we need to do is just remove the lung. You are done." which is not the way Dr. Khullar handle this. He answered our questions, gave us direction and scheduled our follow up with him in 6 months. |
|
08/19/2023 |
I am very pleased with the sincerity of care expressed by my doctors and assistants. They listened to my concerns and answered all questions I had. I feel in very good hands going into my upcoming surgery. |
|
08/06/2023 |
I feel like a broken record whenever I'm asked to do these surveys for Dr. Khullar's office - but I honestly have no complaints or concerns, and I always feel extremely well cared for. (I use survey data frequently in my work, and I know that a long line of top scores isn't always helpful, but I also feel the need to be give honest feedback.) |
