Philosophy of Care

First and foremost, I enjoy being a doctor to children. To me, Infectious Diseases perfectly incorporates clinical work into understanding the epidemiology and physiology of infections. In my current role as Medical Director of the Antimicrobial Stewardship Program, I am fortunate to be able to collaborate with my colleagues across a diverse range of medical and surgical specialties to ensure that we are using antibiotics appropriately, and thereby providing the best pediatric care and ensuring that these life-saving drugs remain effective for future generations.


Kelly Flett, MD, MMSc obtained her medical degree at the University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School. She completed her Pediatrics residency at the Children’s Hospital of Colorado. She worked at Denver Health Medical Center after residency and then came to Boston Children’s Hospital to complete her fellowship in Pediatric Infectious Diseases. Since completing her fellowship in 2014, she has led the Antimicrobial Stewardship Program at Boston Children’s. Her research focuses on antibiotic use in complex patient populations and approaches to reduce inappropriate antibiotic use.
