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 has been the rock in my life who has helped me face my condition w/ knowledge and wisdom and who has supplied the encouragement I need to understand this disease (Multiple Myeloma) and to be able to see the light at the end of my tunnel.

I am so pleased with the extraordinary care and compassion provided by Dr. Hari and the entire team from after-hours telephone line for problem-solving to the friendliness and accountability of the support staff! The RNs and advanced practice professionals are knowledgeable with exquisite skills and demeanor! What a privilege it is to be cared for by such professionals and have access to the clinical trial and outpatient stem cell transplant that have put me into complete remission! The bone marrow/stem cell transplant program is a precious gem in the Cancer Program crown!

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.
