DuPage County Sheriff

James Mendrick


Community Resource Unit

The Community Resource Unit is dedicated to the ideals of community and problem solving policing. CRU deputies work directly with citizens of the county to address existing issues and prevent potential problems.

The unit is made up of Neighborhood Liaison Officers (NLO's), School Liaison Officers (SLO's) and a Drug Education Officer.

Neighborhood Liaison Officers

The Neighborhood Liaison Program was designed to strengthen the relationship between the Sheriff's Office and the citizens it serves, to provide personalized assistance to residents, and to teach residents how to empower themselves so they are able to tackle their neighborhood's problems.

Neighborhood Liaison Officer's act as the primary liaison between the Sheriff's Office and county residents. They also serve as the primary contact for Homeowners' Associations.

Each NLO is assigned to a specific township in the county. They use local Neighborhood Resource Centers as their home base and spend time meeting residents by walking, driving and using specially equipped bicycles to ride through their neighborhoods.

Besides being a visible presence in their neighborhoods NLO's also host numerous programs in their communities from local bicycle rodeos to neighborhood watch programs. They also participate in various events such as the DuPage County Fair and present various educational programs for residents and conduct free home security surveys.

They also handle the Office's popular Cell Link Program and were instrumental in establishing TRIAD/SALT (Seniors and Law Enforcement Together) programs to benefit local seniors.

DuPage County residents who are concerned about a potential, or existing, problem in their community are asked to contact their appropriate NLO via telephone, or clicking the NLO for your specific township.
