He’s put his technical skills into practice to successfully manage projects ranging from a $4.68-million landfill closure project to numerous permitting and design projects for landfill gas systems. He also has managed numerous greenhouse gas and Clean Air Act compliance projects.

“Eric’s diverse expertise is a great fit for us. And beyond that, his principles match the way we approach our work, with a mix of technical excellence and genuine care for the people we work with,” said Patrick Haley, a vice president at HDR.
