Fiorina Kyritsi, MD is an Assistant Professor of Medicine at the Icahn School of Medicine at Mount Sinai, Medical Director for several employer-sponsored Health Centers operated by Mount Sinai Solutions, and the dedicated physician for Mount Sinai's Healthspan Membership.

As longevity medicine has emerged as one of the most closely watched frontiers in health care, Dr. Kyritsi has become one of its few credentialed voices—with a mission not just to extend how long her patients live, but to improve how well they live in those years. She has pursued advanced longevity medicine training with the field’s most respected institutions worldwide, including the American Academy of Anti-Aging Medicine, the Academy for Healthy Longevity at the National University of Singapore, and Israel's Sheba Longevity Center — one of the first academic centers built to translate longevity science into clinical care. She was also an early member of longevitydocs™️, the international physician community advancing longevity medicine, where she continues to contribute as a panelist at conferences.

A Mount Sinai physician since 2017, Dr. Kyritsi brings this depth of training to every aspect of her practice, reading genetics, metabolism, imaging, and lifestyle data not only for what they reveal about a patient's health today, but for what they signal about their health tomorrow.

A native of Volos, Greece, Dr. Kyritsi received her medical degree from the University of Thessaly, graduating valedictorian of her class. When her mother was diagnosed with a heart condition and sought treatment in the United States, Dr. Kyritsi was struck by the standard of care she encountered, an experience that led her to pursue medical training in the United States. She completed her residency in Internal Medicine at George Washington University and a fellowship in Hematology and Oncology at MedStar Georgetown University Hospital.
