Meet the EMS ISD Police Department Command Team

Eagle Mountain-Saginaw ISD is committed to prioritizing the safety and security of every student, along with every staff member and visitor to district campuses. The district uses a multi-layered approach to safety and security, implementing measures to further protect those in our schools and facilities. 

A major investment in safety is the establishment of the EMS ISD Police Department. While Chief Charles Ramirez has led safety and security in the district for over a year, the EMS ISD Police Department received state approval in the Spring, and Chief Ramirez hired the command staff over the summer. In the interim, while the remaining officer positions are hired, School Resource Officers from the Saginaw Police Department and the Fort Worth Police Department will remain at EMS ISD schools. Even after EMS ISD Police take over these duties, the department will continue to collaborate closely with law enforcement in the cities of Saginaw, Fort Worth and Blue Mound as well as Tarrant County to provide support and access to additional resources as needed.
