About

Sentry started as a one crane service company in the oilfields of western North Dakota. That’s where the name originated: just one lone Sentry out trying to satisfy the needs of the customer. Sentry grew from there to servicing all the needs of the oilfield including engineering, cranes, trucking, roustabout, welding, workover, and electrical.

As the company has grown, Sentry saw the need to expand to different industries to sustain a great culture and provide a living for our families. Partnerships were started in the dairy, ethanol, manufacturing, communication, public utilities, water, engineering, green energy, and mechanical. The company Sentry is today began to take shape through great partnerships with our invaluable customers.

Today, Sentry operates as a full-service EPC firm (Engineering Procuring and Constructing). We are passionate in all jobs from big to small, and we are excited about looking at the problems and providing solutions for our customers.

Here at Sentry we pride ourselves in safe and quality services from our administration team to our crews in the field. Our team goal is to provide the best service that our region has to offer.
