Our Stats

Above all, TriStem’s experience sets us above and beyond our competitors. With over 100 years combined experience auditing utility bills, our staff can identify a wide range of errors that other utility audit companies and software programs miss. Many companies are adding utility bill audits to expand their services. In contrast, utility bill audits have always been and will always be our specialty.

Our Vision

To understand the unique energy needs of our clients, help identify and achieve efficiency, and empower every consumer to take control of their utility costs.

Our Mission

Our mission is to bring peace of mind to each client and the security of knowing that they have not paid, and will not pay, more than necessary for their utility services. Deregulation empowers consumers while also leaving them at greater risks. For that reason, TriStem is committed to the highest level of professionalism and integrity while conducting its audits and helping clients understand their utility bills.
