In Brookings, TestMark DNA schedules chain-of-custody DNA collections at 601 4th St, Suite 110, inside the historic 1921 Building downtown. The building is across the street from the lawn of the Brookings County Courthouse at 4th Street and 6th Avenue, where the county's Clerk of Courts is located.
The 1921 Building at 601 4th Street is a renovated historic building in downtown Brookings that combines apartments with professional office space, and TestMark DNA's collection site is in its Suite 110. It stands next to the Children's Museum of South Dakota and directly across the street from the tree-shaded lawn of the Brookings County Courthouse, which sits at 4th Street and 6th Avenue. The address is included in the Brookings Central Residential Historic District on the National Register of Historic Places. Other offices share the building, including a counseling practice in Suite 111, so look for the Suite 110 door once you are inside.

Brookings sits about 55 miles north of Sioux Falls, with I-29 and U.S. 14 as its main highway links, and public transit around the 1921 Building is minimal, so plan to drive.

Brookings is also the administrative base of South Dakota's Third Judicial Circuit. The circuit's presiding judge and circuit court administrator work out of Brookings, and its 14 counties include Lake, Moody, Kingsbury, Deuel and Codington.
