Marisa A. Montecalvo, M.D., a board-certified infectious diseases physician, played a pivotal role in the health care sector throughout their career. From 1999 to 2014, she pioneered the establishment of the position of hospital epidemiologist at Westchester Medical Center and served in that capacity. Dr. Montecalvo's research endeavors and funding were concentrated on hospital-acquired infections, particularly vancomycin-resistant enterococci and Clostridium difficile. She continued doing inpatient consultations through 2019.

Post her tenure as hospital epidemiologist, Dr. Montecalvo assumed the role of Director of Health Services at New York Medical College. Additionally, she directed and worked at the Sexual Health Clinic of the Westchester County Department of Health.

During the COVID-19 pandemic, Dr. Montecalvo had the privilege of working with students and the community. Her commitment to combating infectious diseases persisted, and her recent focus has been on clinical research related to SARS-CoV-2 infection.
