What Sentry does
Sentry, operating as Sentry USA, is a self-performing general contractor and design-build construction firm headquartered in Watertown, South Dakota, with a secondary office in Sioux Falls. The company originated as a single-crane operation serving western North Dakota oilfields and has since expanded into a multi-division construction platform serving commercial, industrial, agricultural, municipal/infrastructure, and renewable energy markets across South Dakota and the broader Midwest, with project reach extending into North Dakota, Minnesota, Pennsylvania, Idaho, and Iowa. Its operations are organized around seven in-house divisions: General Contracting, Electrical, Mechanical, Manufacturing, South Dakota Service, Controls & Automation, and Workover, supplemented by certified/authorized dealer relationships with Brock Grain Systems, Chief Agri, Reinke Irrigation, and Nucor Building Systems.
Sentry's revenue is generated primarily through project-based construction contracts delivered under general contracting, design-build, and Construction Manager at Risk (CMAR) models, plus fees for self-performed trade services and certified product line supply and installation. The technical platform rests on in-house capabilities including CNC machining, MIG/TIG welding, structural steel fabrication, a 40-foot wet paint booth, and a Controls & Automation division that designs and builds UL-listed custom control panels with PLC/HMI/SCADA programming and systems integration. Key customers span municipal governments (Fort Berthold Reservation's $33.3M Bruce A. Fox Water Treatment Plant, City of Mobridge, City of Redfield, Clark County), educational institutions (South Dakota State University, Lake Area Technical College), industrial operators (Midwest ethanol plants, a large Idaho dairy manufacturer), agricultural enterprises (Reinke irrigation installations, Hamlin County's $15MM+ biogas digester facility), and commercial end users. Go-to-market is sales-led, relationship-based, and geographically concentrated in the Upper Midwest, supported by an emergency and service response capability for industrial plant shutdowns.
