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. Fessler is a great doctor. He's very proactive pointing out the best course of action concerning my treatments for Non Hodgkin's Lymphoma. He's an exceptional communicator, always given me extensive attention both in his office and thru my portal. He obviously has a terrific depth of knowledge concerning my disease giving me many options dealing with this disease and how to bring about complete remission. I highly recommend him.

Non Hodgkins Lymphoma
Dr. Fesler is knowledgeable, personable, genuine, and explains the diagnosis and options of treatment throughly! I had lymphoma located in my bone marrow, blood, lymph system and colon. Seven months of treatment put the disease in complete remission. I’m currently on a maintenance treatment program. Dr. Fesler made a difficult health condition easier to deal with because of his knowledge and personal communication skills. I have been blessed to have him as my doctor!

David R Pullen Large B Cell Lymphoma cancer
I was diagnosed with a very large mass of cancer on my Spleen. At St. Lukes Dr. Mark J Fesler recommended a treatment that was relatively new. It was a six month treatment to diffuse large B Cell Lymphoma. After only 3 months the mass had receded by 60 to 70 percent. After the treatment was over my cancer was gone. This was started in about 3-1-2022 and over around 9-1-2022 and as of today I still have no sign of it returning. Dr. Mark Fesler is a Specialist in this field and if you have cancer I highly recommend you seeking his advice. He saved my life and he can do the same for you.
