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.”

Dennis Sizemore

Cement Mason Superintendent

Dennis is the go-to guy on anything and everything concrete. At age 15, he poured and finished driveways, patios, and shop slabs. When he started at GLY at 18, he was the youngest journeyman in his union. Today, he's a concrete master who oversees projects up to one million square feet. His favorite aspect of the job is the constant change of scenery since he's not on one single project for an extensive amount of time. While concrete is a big part of Dennis’s life, he makes plenty of room for his kids, fishing, hiking, and visiting Kauai, his happy place.

Ben Hamm

Project Executive

Assoc. DBIA™

Ben honed his exceptional leadership skills during his first calling as a high school English teacher, coach, and director of admissions. Patient, communicative, and adaptable to change, the AEC industry scored big when he decided to switch gears and earn another degree, this time in Civil Engineering. Progressing from Project Engineer to Project Executive at GLY, he continues to leverage his diverse background—listening intently to clients and teammates prior to making critical decisions. Hailing from Western New York, where cows outnumber residents, Ben remains a loyal Buffalo sports fan—Go Sabres and Bills!
