Our business strategy is simple. Be the best place to work in the industry.
We are ruthless in our pursuit for top talent, holding each other accountable, and delivering the absolute best services in the energy sector. To do this, we focus on the basics like safety, benefits, pay, and a fun culture.
Improving the Community
Spartan believes strongly in improving our community.
The vast majority of our business takes place in rural parts of America. Therefore, we are dedicated to the advancement of the communities we work in, in particular public education. We have already started an award winning school and plan on many more across the U.S.
We are devoted to enriching the lives of our teams, partners and community.
