Sentry is an oilfield and construction service company, locally owned and operated in Watford City, ND.
Sentry started as a crane company whose focus was primarily directed to the oil field. We have now added our roustabout, welding, well services, trucking, and building concepts divisions. In our expansion we have also moved into various fields of construction.
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 oilfield and construction services that the Bakken Area has to offer.
