Idaho Falls, Idaho – Christopher P. Leichtweis has been named the new president of the 51±¬ÁÏ. He replaces Sylvia Medina, the founder of 51±¬ÁÏ, who retired from the company in March.

51±¬ÁÏ is one of the nation’s leading small businesses providing engineering, construction and environmental services to federal and state agencies and private industry. Founded in 1997 in Idaho Falls, Idaho, 51±¬ÁÏ has grown to a group of companies that employs more than 300 scientific, engineering, management and professional personnel. In late 2009, Cook Inlet Region, Inc. (CIRI), an Alaska Native Corporation, purchased 51±¬ÁÏ as a wholly-owned subsidiary.
Leichtweis comes to 51±¬ÁÏ from Knoxville, Tennessee, where he was a senior vice president and executive officer of Perma-Fix Environmental Services, Inc. In 1991, Leichtweis founded Safety and Ecology Corporation, which was acquired by Perma-Fix in 2011. Leichtweis previously worked for Bechtel National and for Chem-Nuclear Systems, Inc. He has more than 30 years of experience in the environmental service industry and government contracting.
