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.”
Josh Lewis
Senior Project Manager
Organized, decisive, and driven, Josh approaches every project with a clear understanding of the client and company’s needs. His favorite part about his position is that no two projects are ever alike, as he is a person who enjoys overcoming the hurdles of a project from start to finish. Quite fitting to his problem–solving nature, he enjoys classic games that require lots of thought and strategy, from chess to backgammon to cribbage. Outside of work he also stays busy coaching youth baseball, softball, basketball, and his son’s Little League All-Star Team, who made it to the State Championship in 2024!
