Arlyn Apollo, MD, MPH

I am a board-certified medical oncologist and internist focusing on the treatment of genitourinary malignancies, including prostate, bladder, kidney, and testicular cancers. I also have a clinical interest in treating gastrointestinal and other solid tumors.

I joined the team at Memorial Sloan Kettering’s regional facility in Rockville Centre, Long Island, in 2007. Here we offer compassionate and cutting-edge treatment for patients who wish to receive Memorial Sloan Kettering care closer to their homes. My goal is to provide the same state-of-the-art care that is offered at our main campus in Manhattan. To that end, I am involved in academic conferences with my colleagues in Manhattan to ensure that I am up to date on the most recent advances in the field.
