The Sheriff’s Office has 3 School Resource Deputies assigned to the Oakfield/Amity, Laconia and Campbellsport school districts.  School Resource Deputies are sworn law enforcement officers/deputies responsible for safety and crime prevention in schools and they work closely with school administrators in an effort to create a safe environment for students.
