ENR Mountain States is pleased to announce the winners of our annual Top 20 Under 40 competition, which recognizes up-and-coming industry leaders from across the Mountain States and Plains region.

The competition has found a big audience in its eight-year history. This year’s contest, which was conducted on a national basis via a series of regional contests, attracted dozens of qualified nominees in our nine-state region alone (Colorado, Wyoming, Kansas, Nebraska, North Dakota, South Dakota, Utah, Idaho and Montana). Across the country, nearly 700 future leaders were nominated based on their career experience, industry leadership, community service and several other factors.

Here, in alphabetical order, are the 2015 winners and their firms. Their profiles will be printed in the February issue of ENR Mountain States.
