Trihydro Moves up in Ranking on the ZweigWhite Hot Firm List of Fastest Growing Architecture, Engineering, and Environmental Firms

(LARAMIE, WY) --– For the fifth consecutive year, Trihydro Corporation, one of the nation’s leading environmental and engineering consulting firms, has been named to the Zweig White Hot Firm List. Zweig White, a management consulting and research firm, identified Trihydro Corporation as one of the 200 fastest-growing U.S. architecture, engineering, and environmental consulting firms for its annual ranking. This annual Hot Firm list features the design and environmental firms that have out performed the economy and competitors to become industry leaders.

The Hot Firm listing is a prestigious national survey of firms that have sustained revenue growth over the course of a three-year period. The 9th annual Zweig Letter Hot Firm 2008 list ranks the top 200 firms based on a combined equal rating of dollar growth in gross revenue and percentage growth in gross revenue. This dual weighting system creates a level playing field among large and small firms. This year Trihydro has moved up in the rankings from 105th in 2007 to a distinguished 65th in 2008.

Mark Zweig, founder and director of ZweigWhite, says, "The firms that made this year's Hot Firm List should be proud. Even with the challenges many firms are facing in this economy, it was still an incredibly competitive and successful group. Firms that commit to revenue growth while investing in marketing, information technology, and other infrastructure are usually the most successful in our industry. They have shown they have the ability to sustain their success, year after year. The hottest firms in the business- those with consistent growth and success at outperforming the economy and their peers- are the ones that attract top staff and the best clients."

Trihydro and the other Hot Firms were recognized at a special reception and dinner at The Zweig Letter Hot Firm Celebration & Conference, held October 27-29, 2008, in Chicago, Illinois.
