Business success hasn’t always come easy for Deryl McKissack and her engineering firm. But a little adversity wasn’t going to stand in the way of success for the oldest minority A/E firm in the nation L 30 ENGINEERING INC. ike most design firms, McKissack & McKissack provides clients and visitors with a colorful, richly detailed portfolio of its many architectural, engineering and program management achievements. But perhaps the best way to truly appreciate the 150-person firm’s success is to take in the view from president and CEO Deryl McKissack’s 10th floor office in downtown Washington, D.C. ■ From there, McKissack can point out historic landmarks and innovative construction projects in which her firm has played a major role—the renovated Jefferson and Lincoln Memorials; the Bureau of Alcohol, Tobacco, Firearms and Explosives’ new 426,600-square-foot headquarters building; the new Washington Convention Center; the Washington Nationals’ new baseball stadium; and many others.
