Mark Humphreys

Mark spent some time as a Project Engineer but after seven years, he found his home in estimating, where he’s been excelling for over a decade. Mark’s expertise in large-scale ground-up or tenant improvement projects made him a welcome addition to GLY, where he put his skills to use on day one. When he’s not busy playing with his daughter and teenage step sons, you’ll find him kicking around a soccer ball, running, golfing, bicycling or hiking with his chocolate lab.
