Danielle Sessler

Senior Project Manager

Associate DBIA™

Construction was always part of the plan for Northwest native Danielle, having grown up in a family that owned a contracting business. She took a few detours first, earning a BFA in Metalsmithing and Art History from Central Washington University and working as a Senior Estimator focused on honing her preconstruction services skills. When she landed at GLY in 2013, we quickly recognized her background would be perfect for Design-Build projects. Outside of work, Danielle enjoys hiking, bouldering, climbing—and collecting “odd things that most people scratch their heads over.”

Today, Allison serves as our Human Resources Generalist, where she plays a key role in recruiting and retention initiatives. Outside of work, she is an avid outdoor enthusiast, loves attending concerts, and can often be found cheering on local sports teams.
