Dr. Sinha is everything I wanted in a doctor. She has 27 years experience in oncology. She was referred to me a year ago by my nephrologist. He said she is as good as it gets in her field. I think he is right. Dr. Sinha's care has remarkably improved my multiple myeloma condition. She is thorough, uses state of the art treatment drugs and medicines, and carefully monitors my progress. She is flexible and modifies my treatments as necessary to balance my comfort with medical necessity. Dr. Sinha has a professional and caring staff. My treatments have been comfortable and painless. She is a superb communicator. I think I am fortunate to have her as my doctor.

My appt was at 10:30, and I was called back almost immediately after I checked in. No waiting in the lobby or in the exam room. They were quick and pleasant, and answered all my questions thoroughly. Check out was a breeze as well.
