Dr. Sarah Fishman is an endocrinologist in private practice in New York City. At her practice in Midtown Manhattan, she provides a wide range of endocrinology care and services.

After completing her medical and PhD degrees at Mount Sinai School of Medicine, she continued her training in Internal Medicine and Endocrinology at Lenox Hill Hospital. She is affiliated with Mount Sinai Hospital and Northwell Health Lenox Hill Hospital, where she serves as an associate professor. As part of her academic appointment, Dr. Fishman has conducted research studies on evaluating biomarkers, chemicals that can be detected by blood tests, to identify patients with diabetes who may be at higher risk of cardiovascular events. In addition, she has spearheaded projects to improve physician and nurse empathy towards patients with diabetes, and on the use of continuous glucose monitors in hospitalized patients.

Recently, Dr. Fishman served as the in-house endocrinologist at Lenox Hill Hospital at the peak of the COVID-19 pandemic, working alongside critical care physicians to develop new protocols for the management of COVID-19 related endocrine disorders. She continues to be a valued teacher and mentor to residents and endocrine fellows.

Outside of the office and hospital, Dr. Fishman is a devoted mother, wife, daughter, and friend. When not on call, she can often be found sleeping in, building crafts with her kids, working on DIY home improvement projects, and enjoying the parks of New York City. She is an active member of her synagogue community and is known among her friends and colleagues for her reliability and fortitude.
