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.

Thorough and professional
Informative and compassionate. Cutting edge on top of the latest research and technology for Cancer patients.

The absolute best
The doctor gave me all the time that I needed and then I wanted. Sometimes 30 minutes or more. One night I was in the hospital and he stopped by at 5 o’clock and stayed till seven. Extremely thorough answers all my questions. A person can ask for a better human being, and doctor. I received chemotherapy in his office, and his staff was very thorough and helpful. My cancer is in the past, but I still care for all the people that treated me in his office.

Dr. Jaiyesimi is an amazingly compassionate, thorough, go the extra mile doctor. The extra effort he puts in to make things right (and right away) and the empathy he is showing me through my Lymphoma diagnosis and treatments is nothing short of a God send!

Dr. Jay and staff did a great job with comforting and taking care of my husband, who passed from pancreas Cancer Nov 15, 2015. He was given 2 weeks on his 51st birthday, but lived 18 months longer. I just want to say "Thank you" for doing your best. I have no regrets. I understand God will always have the final say in all of our lives. God be with Dr. Jay and Staff

Last few years, he has changed a lot. He no longer listens, raises his voice and belittles you. Does not want to explain or answer questions anymore. Rushes in and out, leaves you wondering why you even drove all that way and waited so long to see him. We hire doctors. Does he realize that.

I see Dr. Jaiyesimi at least once a month. He is among the very best of the best oncologists in the greater Detroit area. He was a fellow at MD Anderson Cancer Center and is very active in the field of study of CLL, my particular cancer. He is patient, kind, and will call me day or night as needed. I highly recommend him to anyone seeking cancer treatment at Beaumont Hospital in Royal Oak

My husband passed from pancreatic cancer. Dr. Jaiyesimi may have been educated; however I would go so far as to call him egocentric with a lack for empathy. On one occasion, my shaking, teary eyed husband looked straight into Dr. J. eyes and said, "Dr. I am really scared." Dr. J. acknowledged my husband's heartfelt feelings by stating, "we are all scared; I'm afraid to put my children on the bus every morning." That was it! Silently, we left feeling hopeless and never discussed it again

I love Dr. J! He is extremely competent and the kindest doctor that I have ever met. He takes his time with me and we laugh and joke together. He has such a positive attitude, which in turn, helps me to keep a positive attitude, I wish all doctors were like Dr. J.

This doctor is all about money, it's true that if you don't have the best insurance he will push you into the program he runs on the 2nd floor which are all interns which are trained to only give you one option, the one that makes them the most money. Did you know that oncologist receive a commission for chemotherapy drugs they use! Don't get stuck with one doctor you have time to find a doctor that will work for you. Get many opinions interview them because you are the one hiring them...

My mother lived well beyond expectations after her breast cancer was found to have spread. I accompanied her for many appointments with Dr. Jaiyesimi, and appreciated his excellent communication and human touch. We would strongly recommend him to anyone in need of cancer care.
