Senior Project Manager
As Senior Project Manager at ONE Environmental, Mason McElroy focuses on environmental compliance and permitting needs for industrial clients. He brings years of experience to his new role, having worked as a senior environmental engineer at AdvanSix in Hopewell, Virginia, and as a client manager and project manager in Sage Environmental’s Richmond and Austin, Texas, offices.
Mason joined ONE in October 2021, drawn to its people and culture. “It’s a very relaxed environment, a great work-life balance,” he said. “At the same time, client focus is a top priority.”
Mason never misses a chance to lace up his shoes for a run. He logs between 20 and 30 miles a week and recently completed the 8K course downtown during the Richmond Marathon. Mason was a decorated runner at J.R. Tucker High School and competed in both track and cross country at Columbia University in the City of New York.
Mason was the fastest Lion at NCAA Regionals his senior season — finishing the 10K in a personal-best 31:04. He earned his Bachelor of Science in Environmental Science in 2009. Mason and his wife, Laura, have two children, Landon, 5, and Libby, 2, along with their dog, Junior. The family enjoys camping, and Mason is always in search of another road race or trail run with aspirations to train for his first marathon when time permits.
