William Caruthers graduated from Virginia Tech with a B.S. in Civil Engineering in 1964. Upon graduation, he joined the military and served in the U.S. Army as captain in the Corps of Engineers.
He has more than 50 years of engineering and management experience with both the public and private sector, involving numerous federal, state, and local agencies throughout the United States. He has extensive knowledge of transportation design and planning, water resources, construction management and inspection services, and program management for public and private facilities.

He is a Professional Engineer in nineteen states, as well as an active member of the American Society of Civil Engineers (ASCE) and the National Society of Professional Engineers (NSPE). He is a Fellow in ASCE and served as Chairman of the Water Resources Management Committee of ASCE, District of Columbia Chapter. During his time as chairman, he published the interim storm management report for the Washington, DC metro area.

Until his retirement in June 2015, Mr. Caruthers was the founder and President of ATCS, PLC. He established ATCS in 1994 with six employees focused on Land Development projects. He rapidly grew the firm by adding Emergency Management/Disaster Services for FEMA on a national basis in multiple program areas and a full service transportation department. Now, ATCS has almost 200 employees in seven offices and is consistently ranked in the top 10 engineering firms based on billing in the Washington Metropolitan area. In 2008, the Virginia Department of Transportation awarded ATCS a contract to manage over $5 billion of multiple megaprojects including I-495 HOT lanes, I-95 HOT lanes and the Dulles Rail projects. The contract is believed to be the largest professional services contract awarded in Virginia.
Before ATCS, Mr. Caruthers was employed by Greenhorne and O’Mara (G&O) for 24 years. He held a number of senior level positions before ultimately becoming President. Under his leadership, G&O grew from 115 employees to over 1500, with over 19 offices throughout the United States. During his tenure, he served as Project Director for FEMA’s Flood Hazard Mitigation and Disaster Response Program, performing over 250 floodplain studies and modeling projects. From 1987 to 1993, he served as Project Manager and then as Project Director for the Engineering Review and Cartographic Production for FEMA’s National Flood Insurance Program for multiple FEMA regions. He was the leader of engineering and mapping innovation, mentoring many of the current FEMA contract managers. His staff routinely performed FIS LOMR appeals, revisions, coastal file/data management and H&H studies, completing over 5,000 deliverables.

Mr. Caruthers has been a consistent participant and supporter of Virginia Tech Engineering and the Civil and Environmental Engineering department. He served on the College of Engineering Advisory Board from 1994 to 2000 and the Deans Committee of 100. He was also a member of the Ut Prosim Society and has endowed civil engineering scholarships, striving to give students opportunities to build a career and help others along their path. He is also a founding member of the Virginia Road and Transportation Builders Association, now known as the Virginia Transportation Construction Alliance.

Mr. Caruthers is married and has two daughters and a son. He comes from a family of Hokies, with one granddaughter currently at Virginia Tech, along with several other family members who are alumni of the university.
