Wright County Sheriff protects the public
The Wright County Sheriff’ s Office provides law enforcement services to the unincorporated areas of the county and contracts police services with 13 cities. It is the third largest sheriff’ s office in Minnesota.
The Sheriff’ s Office contracts law enforcement services to every city within the county, with the exception of Buffalo, Annandale and Howard Lake, which have their own police departments. There are five divisions within the sheriff’ s office: operations, patrol, criminal investigations, business administration and corrections.
Sheriff Sean Deringer began his service in Wright County in 1997 as a deputy sheriff. He successfully ran for sheriff in 2018 and assumed office in 2019. Deringer grew up in central North Dakota before moving to Wright County in 1994. He and his family live in Maple Lake.
Deringer heads the office of over 300 staff members including 170 sworn deputies. The command staff is managed by Chief Deputy Matt Treichler and consists of the operations captain, patrol captain, investigation captain, jail captain, office administrator and the divisional lieutenants.
The Sheriff’ s Office hosts ride-alongs for interested community members. Those looking to stay connected with public safety notifications in the community may subscribe to Citizen Alert.

Members contribute more than 4,000 hours each year to the Wright County community, including monitoring public events, providing supplemental patrols and aiding search and rescue operations. The program has been operated in the county for more than four decades.
