Peter T. Masiakos, MS, MD, FACS, FAAP, is a pediatric general and thoracic surgeon at Mass General and Associate Professor at Harvard Medical School. He was trained at the Boston City Hospital and Hospital for Sick Children (Toronto), where he developed a clinical interest in pediatric trauma care and injury prevention. He is the director of the pediatric trauma surgery service at Mass General and has become a vocal injury-prevention advocate. He has broad interest in clinical surgery with a focus on general pediatric surgery (pediatric hernia repair, hydrocele repair, repair of undescended testicles, and umbilical hernia repair), esophageal anomalies, pectus excavatum and pectus carinatum repair, thyroid surgery and pilonidal disease.
Dr. Masiakos has been involved in successfully educating the Massachusetts legislature and the US Congress on the inherent risks that certain products pose to children and has testified both at the Massachusetts State House and at the Consumer Product Safety Commission on the need for new legislation that would prohibit the use of ATVs within specific age groups. He has aided in the development and passage of several forward-thinking injury prevention laws and continues to work alongside Massachusetts legislators and the Congress on several other comprehensive injury prevention laws including junior-operator laws, safe-driving laws and child-restraint laws.
