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.

Dr. Hari and his team have provided me with the very best treatment for my cancer since 2012! In my opinion, Dr. Hari is the reason why my cancer continues in remission!

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!

outstanding reputation and practice that confirms what others say.
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.
May 18, 2019
Dr Hari was transparent,thorough, and responsive to our questions about the treatment process. give him an off the charts rating. Also impressed with entire staff and all verbal and written communication

March 18, 2019
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.

Spoke to him about concerns with my insurance. They're asking to get generic. He said there wasn't and if I needed, he could talk to them. He reassured me that it was ok.
Jan. 21, 2019

on my two year visit I was to have a series of shots that were not scheduled and accommodations were made but it took 2 hours to get the shots. we also waited 45 minutes for my appointment which was scheduled for 12.

Very excellent.
Nov. 23, 2018
I feel that my doctor and hospital staff are watching over me and my condition like i am one of their family. They are constantly aware of my condition and making sure that I am on my way to a total recovery. Thank You so much to their doctor and staff.
Nov. 21, 2018
I did have a change in the dose of 1 prescription. I was told the pharmacy would have the new prescription filled for me immediately. I went to the pharmacy and they said they needed more information on the prescription taking 15-20 minutes. After waiting 1 hour I asked what was going on. They said they received the prescription twice but it was not coded properly. When I had to go back up to the Grace Clinic to resolve the issue, finally someone got it right which took over 1.5 hours.
Nov. 19, 2018
Dr. Hari is awesome.
Nov. 16, 2018
Dr. Hari and his team have been wonderful! We would highly recommend him and his team to anyone battling Multiple Myeloma.
Nov. 15, 2018
We flew in from out of town to see Dr. Hari. The lab was running late so it made everything else late and we had very little time. I had lots of tests run with lab but we didn't have time to discuss results, if they came back. He was very knowledgeable and helpful for the brief time we saw him though.
Nov. 14, 2018
Dr Hari saved my life and every staff member has been wonderful. My wife and myself will be forever greatful!

Nov. 14, 2018
Dr. Hari has always been very respectful and honest regarding my condition. He has a vast knowledge of my illness and I always feel safe with my life in his hands, so to speak. Dr. Hari takes time to listen and makes sure I understand all communication between us. He is, in my opinion, the best of the best.
Oct. 31, 2018
Was a little more rushed at this appointment and did not discuss prescription meds.
Oct. 22, 2018
I have Multiple Myeloma but in a smoldering stage. Dr Hari has stayed on top of my condition very well and even looked at other items that may relate to my condition. He has prepared me for this and gave me confidence for when the time comes to begin treatment.
