Architectural, engineering consulting firm HDR, with offices in Denver, has acquired Engineering-Environmental Management Inc., an environmental sciences and engineering firm with headquarters in Denver.
Financial terms of the agreement were not disclosed. Going forward, e2M will conduct business as HDR | e2M.

Founded in Denver in 1989, e2M employs more than 366 environmental professionals and engineers in 14 offices in the United States, Guam and Kuwait. The firm specializes in environmental compliance, conservation and planning, restoration, engineering and information technology services to public and private sectors, with more than 90% of its clients representing the federal government.

“As part of HDR’s strategic plan, we wanted to expand our federal program, and e2M will be a tremendous asset in that effort,” said George A. Little, HDR Engineering Inc. president. “Their services complement ours well, and our combined strengths create a powerhouse resource for federal clients. We are very pleased that the e2M professionals thought HDR was the best fit for them.”

“We look forward to helping HDR grow its federal program and are excited about the increased ownership and professional development opportunities made possible for our employees,” said Michael A. Cassio, e2M president and chief executive officer. “This opportunity was only possible because our cultures are already closely aligned. Both companies share good reputations, excellent management teams and a stated commitment to doing the right thing for clients. Joining HDR was the right move for e2M.”

Under the new corporate structure, Cassio will be a senior vice president reporting to Elwin Larson, executive vice president and director of HDR’s Environmental and Resource Management group.

The other e2M partners, Executive Vice President Neil E. Botts, and Senior Vice Presidents Brian K. Hoppy, Allan J. Priest and Glen R. Turney will all be senior vice presidents with HDR and will report to Cassio.
