Patient review for Dr. Irfan Khan on Vitals

"She is very inpatient and does not listen to what you are telling her. ... While the doctor is knowledgeable and courteous, the staff seriously lacks professionalism and manners to such a great extent that I have left the practice and found a new endocrinologist."
