Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

good doctor
Dr Obara in my first visit strongly recommend I see Dr Wang a throat surgeon. I did not know at the time that Dr Wang was regarded by his peers to be one of the best. My surgery was successful and my follow up visits with Dr Obara have been professional and reassuring. To date, I am cancer free and hope it remains that way.

Review of my experience with Dr. Obara.
Dr. Obara seems very "textbook" in his style of consultation. He didn't give me much information about my cancer and never told me the type of cancer I had. I looked it up on the Quest website. I asked what side effects of chemotherapy were and he only said I'd lose my hair. I had to look on line to find out most of the information about the cancer and the outcome/side effects. I asked specific questions at times and was not given good answers to the questions. I did attend ASK MY DOCTOR workshops from the Lymphoma Foundation that were very helpful and I asked those doctors questions and found great answers! I found out about this foundation on my own. Cancer was all new to me and I wanted information and felt that I had to find the information elsewhere. Other staff were more helpful that worked in the Comprehensive Cancer Center.

Myelofibrosis treatment
Dr Obara’s no nonsense approach to treatment is appreciated. He is very busy however, and so you have to have your questions lined up or they won’t be answered.
