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.

Hari is always available for questions and concerns. I have seen him multiple times after hours and weekends at Froedtert. I really appreciate how he makes time to discuss how my life is going outside of treatment. He really supports quality of life and ensures his patients are also included in the decision process for the treatment they receive. Thanks again Hari!

May 19, 2019
I find it difficult to communicate with this provider. I feel like I'm taking up his time and not asking my questions in an appropriate and intelligent manner. When discussing my symptoms, he said, Well, all you have is fatigue. This is out of context, yet it remains in my impression of the man. I respect this man for his profound understanding of my disease and I know the treatment is correct.

I have been a patient of Dr. Hari for almost 10 years and I'm so glad that I was referred to him. I have a blood cancer and I believe he helped save my life since my condition is not curable. I am in remission and I have blood work done every three months and I see Dr. Hare once a year now. If I have any problems I just call and I am taken care of. He is a wonderful doctor.
