Mission Our mission is simple. Build it right. Take care of our people. Deliver results our clients can count on.
Sentry is built on five core values: Passion, Integrity, Optimism, Hard Work, and Ride for the Brand.
Flexible. Innovative. Results.
Description Sentry started as a one-crane outfit serving the oilfields of western North Dakota. One crew. One customer at a time. That is how we built our reputation.
Today, we are a self-performing general contractor and design-build construction firm serving commercial, industrial, agricultural, and infrastructure markets across the Midwest. With offices in Watertown and Sioux Falls, our growth reflects the trust of our clients and the strength of our team.
What sets Sentry apart is how we work. Our in-house teams, including General Construction, Electrical, Mechanical, Controls and Automation, and South Dakota Service, allow us to self-perform key scopes and maintain control over quality, safety, and schedule.
From planning through completion, we bring the right people together to get the job done right.
