Sean Sexstone admits that during his first two years of college, soccer was more of a priority than his academics. Sean was on the WVU soccer team and not really into his major. “My schooling wasn’t my focus, when I first started,” he says. Three things changed this for him. First, he transferred to the Industrial Engineering program and he found the course work to be more interesting and practical. Second, he became involved in a serious relationship with his future wife who grounded him, yet challenged him at the same time. Most importantly, Sean’s father was a professor at WVU, and there was “constant attention placed on my academic success”.

Sean had sales experience as early as high school, which he believes led him into a more commercial focus in Engineering. He was part of a vector marketing organization, and by the time he graduated, he was managing more than 150 sales reps in Morgantown.

When Sean graduated, he joined GE Energy in their Commercial Leadership Program. This was a very competitive program that selected only two graduates nationwide. Sean was one of the two. At GE, Sean had exposure to a broad spectrum in the Energy Industry but finally found his way into the Nuclear Industry.

One of his utility clients, Entergy, took a liking to him. “I got to know the Executive team fairly well, and they saw some potential in me”. They made Sean an offer to come to work in Jackson, MS to handle Vendor Performance and Supply Chain across the second largest commercial nuclear fleet in the U.S. At age 27, Sean found himself in a Director position when the average age of his peers was considerably more experienced.

After the time in the Utility, Sean decided to enter the Engineering Procurement Construction (EPC) business. He led the Business Development organization for CB&I (which later become McDermott), a major Engineering Procurement & Construction

company. Their main business was the designing and building of plants in the Nuclear and Natural Gas Industry.

Taking advantage of this diverse experience, Sean was offered a job in Toronto, Canada in 2018. He’s now the Senior Vice President, for Aecon’s Nuclear business where he’s responsible for the operations of the Nuclear business line. Aecon Nuclear is the largest Nuclear Constructor in Canada and is currently under taking significant CANDU Nuclear Refurbishments, Maintenance, and Decommissioning activities.
