Welcome to Holy Rosary Catholic School, located in St. Marys, Ohio. Enrollment is approximately 130 students with 14 teachers on staff, including Music, Art, PE, and Intervention. We are Auglaize County’s only Catholic school, and we are happy that those not living in the St. Marys city district have chosen HRS for their Pre-K through Grade 8 child’s education. Here at HRS, we meet the needs of each student with adaptable programs, allowing him/her to experience success. Our entire program prepares each student to meet the challenges of the future and to share the Gospel message.
