Sentry is a self-performing general contractor and design-build construction firm delivering projects from concept to completion.
With EPC and Construction Management at Risk capabilities, we bring design, planning, engineering, fabrication, construction, and specialized trade services together under one roof. This gives our clients one trusted partner with greater control over quality, scheduling, safety, and project coordination.
Our in-house divisions include General Contracting, Electrical, Mechanical, Manufacturing, South Dakota Service, Controls & Automation, and Workover. Our capabilities also include architecture and engineering, project management, structural steel and miscellaneous metals, custom fabrication, crane and trucking services, millwright work, plant shutdowns, and field service.
Sentry began as a one-crane operation serving the oilfields of western North Dakota. We built our reputation by showing up, working hard, and finding a way to get the job done. That same mindset continues to guide how we work today.
From our offices in Watertown and Sioux Falls, South Dakota, we serve commercial, industrial, agricultural, renewable energy, water and wastewater, and infrastructure markets across South Dakota and the Midwest.
Our people bring practical experience, accountability, and pride to every project. Whether we are leading a complete design-build project, supporting an existing facility, fabricating a custom component, or responding to an emergency service need, we remain focused on delivering solutions that work.
Sentry. Flexible. Innovative. Results.
