About Demytra Mihailidis


It is an honor for me to treat patients from Western New York throughout their cancer journey. I am passionate about providing the latest treatment options for each patient here at Roswell Park. In addition to providing patients and their families with top notch medical treatment, I believe that it is the duty of each physician to guide their patients with empathy, understanding, and excellent communication skills. When a patient enters my clinic, I strive to answer all questions they may have and treat them in a manner in which I would want my family members treated. I enjoy collaborating with each patient and all of the medical professionals at Roswell Park to create an individualized care plan. I enjoy playing the piano and visiting the various WNY beaches with my husband and children.
