Dennis Corporation was recently ranked the 51st most successful architecture/engineering/environmental consulting firm by Zweig Letter’s Hot Firm 2010 List. This list ranked the 150 fastest-growing firms in in the U.S. and Canada. The rankings were determined by the percentage change and dollar growth of the companies over the last three years (2006-2009). This list contains incredible examples of companies that excelled in the face of strong adversity.

Requirements for eligibility in the rankings include being headquartered in the U.S. or Canada and having the majority of corporate income coming from architecture, engineering, planning, environmental consulting, or other similar areas. The criteria used for the ranking was altered this year. Instead of focusing solely on revenue growth, the Hot Firm List now takes into account four factors: percentage change in gross revenue; dollar change in gross revenue; percentage change in pre-tax, pre-bonus profit; and dollar change in pre-tax, pre-bonus profit.

Firms represented in the list will be honored on October 27-28 at the Gaylord National Resort & Convention Center in Washington, DC for an awards ceremony. The Zweig Letter is published by ZweigWhite, which was founded in 1988. Since then it has become a crucial publication for architecture, engineering and environmental firms around the country.
