Partner, Louis Berger Associates, Harrisburg, PA, 1953-1980s ; his engineering consulting practice grew into a contracting and design business for infrastructure projects globally called Berger Group Holdings (BGH). In 2013, one subsidiary of BGH was the Louis Berger Group, Incorporated (LBG), an engineering "consulting firm that provides engineering, architecture, program and construction management, environmental planning, and economic development services." Early in his career, Berger's company received large building contracts for construction of the Pennsylvania Turnpike. The fast-growing firm opened a second office in 1954, and reestablished its headquarters in NJ, in 1962, a site closer to large-scale work in New York City. (The firm relocated its headquarters subsequently from East Orange, NJ, to Morristown, NJ.) Co-founder, Berger/Abam Engineers, Morristown, NJ and Federal Way, WA, 1988-present; BGH was a huge government contractor in 2013, the third largest private partner contracting with USAID, the international development assistance agency founded by President Kennedy in 1961. In 2010, BGH settled a $69.3 million fraud case with the US Government for added "internal costs" not incurred during contracted construction work in Afghanistan. It was the largest settlement to date for war-zone contract fraud with the US Government.

During World War II, Berger served with the US Coast Guard, assisting in the construction of port facilities on the Mississippi River and commanding a Coast Guard base in Greenland. After the war, he returned to IL to complete doctoral study at Northwestern University. He graduated and landed a job at Penn State University in their Civil Engineering Department. He worked here briefly, when he left to found his engineering company in 1953. The firm's growth was greatly expanded by its contract to build large portions of the Pennsylvania Turnpike. In retirement, Berger maintained residences in Delray Beach, FL, and Verona, NJ.
