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.

Dr Sinha was very thorough with my care. Not all doctors are as comprehensive as she is. She reviewed my tests, pertinent medical history, spoke with my referring doctor, and consulted a colleague before my visit. She then explained in detail my possible diagnosis, reviewed my tests with me, and gave me time to ask multiple questions and come up with a plan of action. She is very respectful, knowledgeable, experienced, and compassionate and it comes through during her personal attention to you during the visit. As a patient and as a health professional I would highly recommend Dr Sinha.
