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.

Monty Kilcup

Principal

Monty brings tremendous energy and ingenuity to his clients. He built his career at GLY by delivering creative, value-based preconstruction services, and accurate, timely estimating based on his deep knowledge of current market unit pricing and trends in commodity pricing. Monty works closely with an agile group of construction management, design, and craft professionals who flex to the ever-evolving needs of a project. He is a specialist in the occupied environment, always thinking outside project confines to develop innovative solutions.

Laura Soma

Sustainability Manager

LEED AP BD+C, LFA

It’s no wonder that Laura’s passion is helping people find their potential. She’s worked hard to creatively forge her own career path and achieve her goals. She is active in a number of industry groups and peer networks focused on green building and leads GLY’s internal sustainability efforts. Her background as a Project Manager allows her to connect with clients and project teams to drive sustainability project goals while keeping budget and schedule at the forefront. Laura brings her love of responsible practices [and infectious good spirits] to every project.

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.

Michelle Connor

Business Equity Specialist

Since joining GLY in 2019 as a Project Coordinator, Michelle steadily assumed more and more responsibilities, eventually combining her personal interest in DEI with our clients' goals for trade equity. Naturally she signed up for our corporate DEI Committee, where she continues to make a valuable impact. As our Business Equity Specialist, Michelle provides project team guidance and support to achieve MWSBE and apprenticeship utilization goals, develops community engagement initiatives, and maintains ongoing community and industry involvement to deepen relationships within the public sector and ensure current knowledge of local, state, and federal regulation for adhering to contract requirements. When she’s not busy chasing her turbo-charged toddler, she’s dreaming up new book club picks that will either dazzle her coworkers or make them question her taste in literature.
