Our History

---

CIS Development Corporation was originally part of Copperstate Companies, founded in 1995 by Thomas C. Oakes. Tom began his career in 1987 with Equipment Maintenance Services, where he provided on-site maintenance for mining equipment across the Western United States. After eight years at EMS, he founded Copperstate Companies, which included Copperstate Construction, Copperstate Industrial Services, and CIS Development.

Copperstate Companies quickly gained recognition for its expertise and reliability, growing into the official on-site maintenance contractor for nearly all the mines in Arizona, Nevada, Colorado, and California by the early 2000s. Their reputation for quality and efficiency allowed them to dominate the industry, offering essential services that kept mining operations running smoothly.

In 2009, Tom decided to shift focus to Industrial and Commercial Construction. He sold the mining division, Copperstate Industrial Services, and retained Copperstate Construction Services and CIS Development Corp. Today, CIS Development continues to build on this legacy, offering exceptional construction services across multiple sectors with the same commitment to excellence and reliability that made Copperstate Companies a trusted name in the mining industry.
