Service with understanding and compassion is my goal in providing care to cancer patients. Advances in cancer care are remarkable and all patients deserve access to the best care with reassurance everything possible is being done for recovery and cure.


Dr. Longo attended medical school at the University of Nebraska Medical Center and then Internal Medicine at the Mayo Clinic before training in Hematology and Oncology at the University of Wisconsin-Madison. He was at UW-Madison when they did their first bone marrow transplant .Now at the Medical College of Wisconsin, he is able to continue clinical transplants and participate in innovative cellular therapies.

Dr. Longo has always been very confident, patient, and kind with me throughout my cancer diagnosis and treatment. He has never made me feel rushed and has always left ample time for any questions or concerns that I may have. It has made this unexpected ordeal much easier to deal with. I have always had full trust in his care and expertise, and continue to do so.

My biggest complaint is that the doctor was almost 2 hours late for his appointment! I saw his nurse practitioner before Dr. Longo and she was excellent. Showed me my test results, explained them and my status. Spent much more time with her than the doctor.

The perso who drew blood on level 2 was not friendly, and did a poor job of inserting needles. had to go to other arm, did not relax me and did not have a name badge. Needs training on how to relate to patients and how to draw blood
