Cameron Cole

Senior Project Engineer

A Bellevue native, Cameron built the foundation for his career through several internships at GLY and earning a BS in Construction Management from Weber State University. His project experience thus far has focused on downtown Bellevue, including the Lincoln Square Expansion and West Main mixed use development. Off the jobsite, he’s an avid outdoorsman – hunting, fishing, skiing, and backpacking – and volunteering as a member of the King County Search and Rescue team.

Steve Hoffmann

President+CEO

LEED AP BD+C

Steve feels at home with just about everyone. In his view, working with field crews, subs, engineers, architects, clients and “our first-class teams” makes each day unique. His 25+ years with GLY encompasses a wide range of market sectors, from fast-paced, ground-up construction of new office buildings to roadway and utility projects, garage structures, and challenging phased renovation work for educational facilities. He delivers predictable results every time and cultivates a strong team atmosphere focused on quality and superb customer service. Besides loving his job, he’s an inspiring volunteer, mentor, football fan, outdoorsman and family man.

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.

Mike Martel

Senior Project Manager

Associate DBIA™, LEED AP BD+C

Mike joined GLY in 2013 as a Project Engineer and has steadily increased his responsibilities, becoming a Project Manager in 2020. He holds a BS in Construction Management from the University of Washington, where he later returned to earn a Commercial Real Estate Certificate. That’s just one example of Mike’s passion for continuous learning—and sharing with his teammates. He’s especially versed in the latest developments in 3D modeling and navigating the complex processes of advanced BIM visualization. After a long week at work, Mike burns off steam by running, cycling, and skiing.

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.

Cassie Withrow

Executive Administrator+Administrative Services Manager

Excellent customer service comes naturally to Cassie, who approaches every task with a can-do attitude. As Executive Administrator, she enjoys working with people that encourage her and test her limits but allow her to have fun along the way. She manages her time—and many others’—with extraordinary ease and keeps things running like a well-oiled machine. Outside the office, you’ll find Cassie hiking, exploring the city, and when the sun comes out, boating on Lake Washington—all with her husband and pups by her side.
