Dr. Azuma is an amazing professional and personable doctor! His RNs and office staff are always welcoming and on top of their game. Can't ask for better people to put my trust in.

November 22, 2019 9:52 AM

Dr. Azuma is an excellent health care professional as is Dr. X. All drs. that I have visited have been excellent.

November 11, 2019 5:21 PM

For a first visit, I thought it went well. Doctor provided information that I asked about.

October 15, 2019 7:00 PM

Dr. Azuma is an Oncologist. He has treated me for 22 years for three different kinds of cancer. His excellent treatment and assessment of my cancers has helped keep me alive for 22 years. He has been instrumental to recommending other specialists for my treatment when necessary. He is truthful and attempts to answer all my questions directly when I have demanded answers;

December 16, 2018 6:00 PM

I see Dr. Azuma every six months as I had Non-Hodgkins lymphoma in 2004. I was treated and I no longer have it. I go every six months to make sure it has not come back. All these years of visits, all staff or at least some staff have been here since my very first visit. All are very friendly & caring. Overall I couldn't ask for a better doctor & staff.

December 13, 2018 6:00 PM

Dr. Azuma has been my oncologist for 21 years. He is the best! I trust him and his judgment. He has brought me thru some tough times.

I have great respect and trust for this physician.

November 29, 2018 6:00 PM

Even tho Dr. A. performed my basic annual breast exam & listened to my chest, he seemed preoccupied. Had not examined my latest mammogram results. Spent no more than 5 minutes with me. Failed to mention I am due for a DEXA scan which he usually orders. Felt visit was less than satisfactory.

October 22, 2018 7:00 PM

I see Dr Azuma every 3 weeks for my chemo. He and his office staff in Darien are part of my family. I'm now 2 1/2 years past my life expectancy of 1 year. That's Dr Azuma and his team. I thank God, he's my doctor.

October 9, 2018 7:00 PM

I have been seeing Dr Azuma since my cancer diagnosis in 2010. He and his team have been wonderful. I would recommend him to anyone facing cancer.

August 17, 2018 7:00 PM

I am now sleeping at night thanks to Dr. Azuma listening to me an about my insomnia and prescribing something mild to help me sleep at night.

August 10, 2018 7:00 PM

he dismissed parts of the test results as unimportant without telling me what it was or why it was irrelevant. I think I should know that.

May 21, 2018 7:00 PM

Dr. Azuma is respectful, very knowledgeable, and truly loves what he does.

May 2, 2018 7:00 PM

Dr. Azuma and his entire team are terrific. Unfortunately, the wifi in the Darion Facility were I see them is not good. It almost never works well enough for me or my wife to use it. This is somewhat surprising as three years ago I/we spent several months under Dr. Azuma's care at this same facility and the wifi worked very well then.

April 28, 2018 7:00 PM

Dr. Azuma was very professional and answered all of my concerns with compassion.
