      Dr Nisha Hariharan is amazing. She is proactive in my care, very thorough, explains my condition in detail and in terms I easily understand, and offers options in follow-up. I am so happy that I'm her patient. I previously saw a different hematologist at another provider, and am thrilled to have switched and found Dr Hariharan.

      The Dr who saw me was excellent. She was extremely thorough, she took the time to hear my concerns and had great insight to how things were going to move forward. She was very reassuring, she cared. It was a great appointment.
