Thomas A. DiPetrillo, MD

Clinical Director, Radiation Oncology

Thomas DiPetrillo, MD, is clinical director of radiation oncology at Rhode Island and The Miriam hospitals. He is a leading authority on a variety of radiation treatments for cancer, including intensity modulated radiation therapy (IMRT) and high dose rate (HDR) brachytherapy. DiPetrillo is a pioneer in the use of IMRT, a noninvasive procedure that allows physicians to pinpoint delivery of radiation therapy, resulting in better tumor control with less toxicity. He is also an expert in the use of HDR brachytherapy, a treatment that involves the use of a robotic arm to deliver a radioactive “seed” to a tumor. 

DiPetrillo is a graduate of the University of Vermont College of Medicine and completed his residency at New England Medical Center (now Tufts Medical Center). He is an associate professor of radiation oncology at The Warren Alpert Medical School of Brown University, and an adjunct associate professor at Tufts University School of Medicine.
