History

Core States Group℠ was formed in 1999 by John M. Scheffey with the original goal of providing engineering and project management services to the retail petroleum industry.

This seemed a natural fit due to Mr. Scheffey's previous experience in construction and development engineering for industry leaders Amerada Hess and Sunoco. Core States Group (CSG) quickly became the go-to design and engineering partner for the petroleum industry, building relationship with many of world’s top brands. This early success formed the foundation of the company's growth beyond engineering and project management services to our position as a total integrated services provider. In 2008 and 2009 CSG was recognized as one of fastest growing companies on the Inc. 500 list.

CSG continues to anticipate customer needs and has made a significant impact with emerging technologies resulting in cost savings and progressive systems development. Our work in alternative energy has allowed us to be the proud of Bloom Energy and Walmart on alternative energy programs including wind turbine, solar, and fuel cell development.
