HOPEDALE/MARLBOROUGH – A former Hopedale nurse accused of sexually assaulting teenage boys while working at Boston Children’s Hospital is now facing additional allegations involving an adult patient.
John Tam pleaded not guilty Monday to charges stemming from incidents prosecutors allege occurred in 2022 and 2025 at Boston Children’s Hospital.
According to the Milford Daily News, Tam is also accused of sexually assaulting an adult patient while working as a nurse at UMass Memorial Medical Center Marlborough in 2023. He was arraigned on that charge last year and has also pleaded not guilty. The cases remain pending in court.
