2026 GLY Construction, Inc.

Steven Siler

General Foreman

Steven is a detail-oriented professional known for his resourcefulness, problem-solving abilities, and strong communication across diverse teams. With experience leading work, maintaining schedules, and overseeing quality assurance, he brings a well-rounded, hands-on approach to every project. Steven’s career began with lutherie—the art of crafting stringed instruments—which sparked his passion for woodworking and led him to run a custom cabinet business in Arizona for over a decade. After relocating to the Seattle area, he joined the Carpenters Union in 2016 and continues to build a career grounded in craftsmanship and service. Outside of work, Steven is an accomplished musician who plays drums for the Seahawks [while playing a wide variety of other instruments at home as well] and has traveled to over 24 countries.

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.

René Ansdell

Senior Project Engineer

LEED Green Associate

René’s background in construction management and architecture provide her with a fluency in both languages, adding value to each of her projects through this diverse perspective and the ability to see the bigger picture. She is highly detail-oriented, an eager learner, and always emphasizes the importance of staying in close communication. After work, you can find René hiking, painting or drawing, or playing softball and flag football.

Logan Chun

Senior Preconstruction Engineer

LEED Green Associate, CESPL

Logan brings his personal obsession with timelines and coordination to his career in Preconstruction. He is a person who likes to take immediate action, because as he describes it: "In Preconstruction, success is built on momentum". To maintain this focus, Logan tracks three key wins in a daily journal–instilling the habit of keeping a project progressing and on track. This is an excellent tool for keeping him motivated and passionate, and he finds these "small wins" to be his favorite part about working in this industry. Weather permitting, you can find Logan enjoying his spare time outdoors, whether it's hiking excursions, camping, boating, soccer matches, fishing trips, or snowboarding.

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.”

Laura Ovsak

Project Manager

RA, AIA, LEED Green Associate

Laura joined the GLY team in 2017 after spending five years with architecture and engineering design teams. Her varied design experience provides a deep understanding of the design process, and a fluency in the design language. Having worn many hats at GLY, she has developed a diverse skillset, carrying many projects through their phases. Laura recently completed the process of becoming a licensed architect!

Cesar Torres

CFO

As a natural strategist with an adept financial insight, Cesar contributes immensely to the long-term success and profitability of GLY. As our CFO, Cesar oversees all accounting, financial reporting, and risk management functions. He partners closely with executive and operational leadership to drive financial performance, support strategic growth initiatives, and ensure strong fiscal stewardship across the organization.

Cesar spent more than 25 years in the construction industry before joining GLY, and values working in an industry that builds tangible, lasting structures. Outside the office, he is deeply family oriented–no small feat with more than 100 first cousins! Cesar spends much of his free time visiting family, playing sports with his kids, and volunteering within his community.

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!
