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.

Dr Osman and staff are fantastic!!

Excellent Doctor.
Dr Osman always remembers us even though we only see him on a 6 week schedule He takes all the time necessary to answer all our questions and concerns. We are very happy that we were referred to him when my previous Oncologist retired.

My Profound Gratitude for Dr. Osman
From the moment I met Dr. Osman, a sense of profound relief washed over me. It was as if a weight, heavy with fear and uncertainty, began to lift. My journey with cancer had been a whirlwind, a chaotic storm of diagnoses and anxieties. But Dr. Osman, with his calm demeanor and unwavering confidence, immediately became my anchor. He didn't just see a patient; he saw a person, a life disrupted, and he took immediate, decisive action.My case, I understand, was far from straightforward. It wasn't a textbook scenario with a clear-cut solution. It was a complex web of challenges, requiring a patient, methodical approach. Dr. Osman didn't shy away from this complexity. Instead, he embraced it, meticulously crafting a 'plan of attack' that, in hindsight, proved to be the very path to my remission and recovery. He didn't rush, didn't make assumptions, but instead, took the time to understand the intricacies of my condition, carefully considering each step. I am forever grateful for Dr. Osman

Competent, Caring and Compassionate
I am so happy I was led to Dr. Osman. He spent time fully understanding my case, collected the necessary data and identified alternative options for treatment. I ended up doing a clinical trial with tremulously positive results.

Outstanding!
I was delighted to discover on my first appointment that Dr. Osman uses a holistic approach to medicine; YES, lifestyle and diet play key roles. Dr. Osman spent considerable time asking questions and listening, building a full profile of my health history and my personal goals. He valued my opinion. When I wanted to apply lifestyle and diet changes to see if I could affect a change in a lab result, (rather than take a prescription medicine), Dr. Osman was willing to accommodate that. Wow!

Best Oncologist I have ever had!!!
He was not rushed and wanted to make sure I understood my cancer. Showed genuine interest in me. Gave me advice on ways I could help stay healthy. Concerned about my mental health. Explained my test results and most of all was very open to hearing my questions and concerns.

Dr. Osman is approachable and personable, reassuring and comprehensive in explaining his findings and what he does. I felt comfortable asking questions and talking about a few delicate issues I had. I’m confident in his expertise in hematological conditions.

The Best Oncologist
Dr. Osman thoroughly reviewed my records and patiently explained the diagnosis and treatment. He knows the new and improved medications and lab test to treat cancer. After 1 visit he accurately diagnosed and prescribed the latest drug that target this particular cancer type. The new drug is extremely costly, he and his staff helped get the medication approved by insurance. Without his help, I would not be able to receive the drug and continue the treatment. It is also very easy to make an appointment and he always on time. I highly recommend him to anyone who looks for competent, kind and compassionate practitioner. Many thanks Dr. Osman.
