I believe that cancer treatment needs close partnership between patients, their families and their physicians so that the latest advances in diagnostics and therapy can be brought to the bedside in a timely fashion. An important goal of my practice is to inform and empower patients about the various therapeutic choices including clinical trials.

My provider treats me like I want to be treated. He talks to me one on one like I would talk to my brother. He discussed everything that I go through and has the answers to all my questions about my health. I am very happy with the way he takes care of me.

May 7, 2020
I have a lot of confidence in Dr. Hari. He is caring and funny. I understand how much positivity is part of his belief system in how patients do. He explains things well in the general sense, but he doesn't like to give too many details or to explain the "why" of his decisions as much which I do like. (I tend to be a person who doesn't listen if I don't know why:)

I met with Dr. Hari for a second opinion consultation about a specialized procedure and follow up care for that illness requiring the procedure. He explained all of laboratory test as well as his current laboratory test results and how they related to one another. He explained the status of my illness and the medication said I was on better than any doctor I had previously seen for the songs. He was very kind and he answered all of my questions. He did not mind if I interrupted him for a moment To ask for the question on issues that we were discussing. I was amazed at his patience and humility and willingness to help in anyway that he could to facilitate my treatment.
