Dr. Kullah described and illustrated the procedure to be performed in layman's language that was clear and understandable. He gladly answered questions and concerns. His presence was calming and friendly, putting me at ease.

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.

The whole experience with this office staff and Dr was amazing. I see many drs and this team really shines. I never felt like just a number or another patient, but I did feel valued and heard, especially by Dr. Khullar.
