Benji Dimer

Project Manager

LEED Green Associate

Since joining GLY in 2017, Benji has distinguished himself as a trustworthy team leader who is continuously learning all he can. He is often the first to arrive and last to leave—by choice!—as he truly enjoys his work and is always willing to take on new challenges, mentor others, and push himself to keep learning and growing. Benji can also often be found biking and enjoying the outdoors.

Katie Focher

Senior Project Accountant

Katie ventured west from Missoula, Montana to attend Central Washington University where she majored in recreation and tourism and played softball. We love having a ringer on the GLY softball team! When she’s not managing the books for GLY projects she likes to golf, hike, go wine tasting, and watch the Mariners. Her bucket list includes a trip to every MLB stadium, minus Yankee Stadium.

Donovan Mabbott

Superintendent

Over the last 30 years, Donovan’s appreciation for quality craftsmanship combined with his natural ability to manage the many moving parts and pieces of a construction jobsite from start to finish has garnered trust and respect from GLY employees, trade partners, and clients. From interior build-outs to full campus developments, he approaches each project by tapping into each team member’s strengths, talents, and skillsets to develop a thoughtful plan—together. Witnessing that plan unfold successfully is his favorite part of his job. On the home front, there is never a dull moment with his four kids, granddaughter, and three dogs—each bringing joy to the family with their own unique personalities. Skylar, the littlest pup, runs the pack.

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.

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.”

Ben Hamm

Senior Project Manager

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 Senior Project Manager 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!
