Top 250 Private Companies: 31 firms top $100 million, led by DCP Midstream for third straight year.

• Author: Sukin, Gigi

The thriving statewide economy - comprised of industries from energy to health care, technology to construction, manufacturing to financial services - is often attributed to quality of life, an educated workforce, and recreational and cultural attractions.

This July, Forbes magazine placed five Colorado communities - Denver (No. 1), Fort Collins (No. 10), Boulder (No. 26), Greeley (No. 33), and Colorado Springs (No. 37) on its annual ranking of the best U.S. cities for business and careers.

That economic strength is also reflected in ColoradoBiz magazine's annual compilation of the Top 250 Private Companies in the state. For the third consecutive year, DCP Midstream made the top spot, grossing more than $14 billion in 2014, up roughly $2 billion from the previous year. The highest employment stat goes to CH2M Hill, the Denver-based global engineering, consulting, construction and operations firm, with roughly 25,000 workers worldwide. More than 30 companies earned $100 million or more. Read on to find out which Colorado companies made the cut in 2015.
