Our Culture

From our rapid growth as a small regional company to a leader in our industry, CST has developed an attractive culture resulting in a desirable work environment. It all starts with safety. With solid backing from our leadership team, the employees of  CST understand that all incidents are preventable and that priority one is having all employees go home healthy every day. Every employee has been trained to take personal responsibility for their individual safety as well as the safety of their entire crew.

We have developed a “family feel” to our Company. Having a diverse mix of employees with a wide variety of experiences from both large and small service companies has significantly strengthened our knowledge and skill base.

Hiring experienced oilfield workers and using them to work side-by-side and train “green hats” has created strong bonds between our crews. Progression “up the ranks” with a structured foundation of training provides new employees with a clear understanding of advancement opportunities within the organization. Our competitive pay and generous benefit plans allow employees to focus on safely performing their work.
