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.

I’ve been 4 times. The shortest wait after my appointment time was 45 min. The longest was 5 hours. Since they take your copay when you sign in I couldn’t even get a refund and leave. Had several issues with the office not scheduling other test in time for appointments and even watched two workers taking my blood samples almost fist fight. Doctor seems good, but the office is lacking greatly. I get penalized if I’m late for an appointment, why can’t they start taking money off my bill to recoup lost wages waiting away in a waiting room.

My mom was diagnosed with lung cancer in 2014. Dr Kleinbaum was an amazing doctor through her fight and the loss of my just a few months after she was diagnosed. He was always willing to allow me on speaker phone when I couldn’t make it in town and answer my million of questions. My mom always felt comfortable being in his care. He would always personally return my phone calls and while he sometimes delivered bad news it was always so kind with the best bedside manner. He even called when she passed away and was no longer in his care due to her moving to live with me in DFW. Our family was very Thankful for him during what is such a hard time.

Dr. Kleinbaum and the entire staff at Millennium have proven themselves over and over again during the past year in my treatment of cancer. I can't say enough in praise for him and the Millennium staff. Dr Kleinbaum is knowledgable, caring, and extremely supportive and I just want to share this with potential patients. Additionally, John with Waldron Medical Research, has been a God send for me. His compassion and support has been invaluable in my care.

Dr Kleinbaum was recommended to me by my primary physician and a good friend that uses him. I had an oncologist/hematologist that I found uninterested in me and was looking for someone that would atleast look at my chart to know what had been done. Dr. Kleinbaum does that, he takes time to talk to me and more importantly listen to me. I understand tests may not show what the doctor might think but it is my body and I know when things aren't right. I found this with Dr Kleinbaum. Everyone in the office is really nice but Sandra has gone above and beyond. Insurance company has balked at some tests and Sandra and Dr. Kleinbaum have been dealing with them to get what he thinks needs to be done is done. I'm very happy with my change in doctors. My primary told me he was recommending an eagle and he did.

One of the most considerate and caring physician’s my husband and I ever met. Dr. Kleinbaum knows his business. My husband and I have the utmost confidence in this doctor and to us, that’s a big deal as it should be with anybody fighting multiple myeloma or any other cancer. He explained everything in plain English from the very first visit and always answers any questions we may have. His staff are always kind and considerate of my husband’s needs.

Hello. Dr. Kleinbaum treated my mother, Lillion Reynolds, for lung cancer several years ago. He was very kind, and always took the time and care to be with her, and explain all treatments and options. To this day, I am grateful for Dr. Kleinbaum’s kindness and courtesy. Thank you.

Absolutely love Dr. Kleinbaum. He's thorough, in fact when he tells you he'll get back to you, he does. Dr. Kleinbaum has even called after 7:00 PM on a Friday night (he's a man of his word) to keep us informed as he hadn't gotten test results back before my husband's appointment. We've jokingly asked him if he has a life outside of work as he's so dedicated to his patients. So grateful my husband's oncologist is Dr. Kleinbaum.

If it has not been for the fast acting staff (Katie) and the quick thinking of Dr. Eric Kleinbaum, I would not be here. He saved my life. The staff that has been taking care of me with my chemo treatment are absolutely a breath of fresh air. I have and will continue to recommend him to anyone who wants the best treatment for cancer.
