Such a gifted doctor and communicator. If you have to go through this, you want Dr. Sinha on your team.

April 2026

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.

Dr Sinha is very thorough and professional in her approach. Breaks things down in her explanation of what she is recommending and why. This includes writing this down while explaining what may be happening, and her approach to address issue.

March 2026

Dr Sinha is kind, knowledgeable, professional and takes the extra time to explain the science and the practical application to how you want to thrive post cancer and monitor for recurrence. I travel 4 hours each way for my appointments and will continue to do so to access her skill to help manage my care. So grateful for her and the staff in both her offices.

March 2026

The staff is calm and patient with the guests. Yes, I said guests, because even though I am a patient, I didn't feel rushed through a visit as if I was just a medical record number. Everyone is courteous and kind. Dr. Sinha just ties the bow of care with her calming demeanor and encouraging voice. She explained my labs and options for future care, reassuring me that if or when I needed a plan put together, she would be there to help guide me to a healthy solution. I appreciate how detailed and supportive, as well as thorough they all are. Also, the ladies at check-in and check-out are very nice and take discretion very seriously.

Most professional! Most knowledgeable! Dr. Sinha takes the time to explain everything regarding course of the disease, how to treat symptoms and possible side effect of meds, etc. Dr. Sinha has a great bedside manner. She's very sweet and compassionate. I highly recommend her!

Dr. Sinha is very patient, an important skill in Oncology. She answered all of my questions and provided common sense and transparent direction for ongoing navigation to obtain answers outside of her clinical expertise.

Dr Sinha makes me feel completely at ease with her warm, calm demeanor and professionalism. Her concern about patients well-being is genuine and comforting. When dealing with the subject of cancer, that is huge. She has provided me excellent care and I will continue to see her with any future health concerns.
