John C. Deerkoski Joins Thornton Tomasetti as Senior Principal and Transportation Practice Co-Leader

Thornton Tomasetti announces that John C. Deerkoski, P.E. has joined the firm as senior principal and Transportation practice co-leader. Based in the New York office, Deerkoski will partner with Senior Principal and Transportation Practice Co-Leader Sam Summerville on the strategic growth and overall management of our transportation and infrastructure groups.

“We are pleased to welcome John to the executive team,” said Thornton Tomasetti Managing Director Gary Panariello. “His extensive technical background, industry experience and team-building leadership style make him a good fit for the expansion of our Transportation practice. Together with Sam, John will focus on ways of working smarter and better for our clients while creating new opportunities for the advancement of staff.”

Deerkoski has 34 years of experience providing transportation engineering services to public and private clients. During his career, he has amassed a diverse portfolio that includes many of New York City’s major bridge, transit and infrastructure projects.

Cuomo, Verrazano-Narrows, Ed Koch Queensboro and Brooklyn Bridges, Queens Midtown Tunnel and Grand Central Terminal as well as projects for Metro-North Railroad, Long Island Rail Road, and New Jersey Transit. Prior to joining Thornton Tomasetti, Deerkoski was a vice president at AECOM, where he was responsible for overseeing the bridge and transportation alternative delivery practices for the New York region.

“This is a pivotal time for the transportation and infrastructure industry,” Deerkoski said. “Many of our roads, rails, bridges and ports are nearing the end of their lifespans and can’t keep pace with increasing demand. As the public and private sectors look to build a transportation and infrastructure network for the future, they will turn to firms like Thornton Tomasetti to provide innovative, yet practical, solutions. I look forward to working with Sam and the rest of our team on ways to effectively address these challenges and grow the Transportation practice.”
