General Info

Danmark Security currently has more than 150 security professionals posted in the Chicagoland area and is on the move as more and more perspective clients make their way through its phone lines. The company was founded by Mark A. Delia and Dan Petronijevic and first officially opened its doors on November 1, 2001. While it is a young company, its experience goes far beyond that of some more tenured competitors. The two main principals of Danmark Security maintain a track record in safeguarding major commercial office buildings, residential properties, industrial sites, private property and people.
