Bill DeJarlais

As an Executive with a career spanning over 30 years across a wide spectrum of market sectors, Bill enjoys helping our highly capable builders lean into their relationships and take the responsibility needed to help our clients and partners succeed. Trained in architecture, he’s sustained an appreciation for design and has helped advance internal tools and technologies that help make GLY more proactive partners through every facet of a project’s life cycle.

With over 40 years of experience in construction, Tony is a renovation specialist who works closely with our clients to tailor solutions to each project's unique goals and requirements. He's led projects at airports, hospitals, universities, fire stations, and everything in between.  Safety is always his top priority, especially in occupied, sensitive spaces where the comfort of patients and staff is paramount.

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.”

Nate Downs

Assistant Yard Superintendent

Since joining GLY in 2010, Nate has been a valuable member of our Tool + Equipment Yard team, playing an integral role in the smooth operation of our projects. In addition to his supervisory duties, Nate also supports projects through GPR scanning services. Outside of work, Nate enjoys spending time with his wife and two adult children. He is passionate about all types of outdoor activities, particularly those shared with his family.

With over 25 years of experience, Tyler delivers some of GLY’s most complex projects. His background in engineering, a number of certifications, ongoing industry education, and a full spectrum of market sectors on his resume bring a blend of professional knowledge and building capabilities that are ideal for highly technical projects. His approach? A balance of strong leadership and communication.

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!

Tess has built her career at GLY, from humble beginnings as an intern, advancing steadily to a promotion in 2019 to firm principal. She is a dedicated, selfless leader who pays careful attention to every project’s specific vision, technical complexities, and goals. Tess is very effective at coordinating the efforts of design professionals, construction teams, corporate stakeholders, and owners while integrating various service providers into project delivery. She chairs GLY’s internal DEI committee, which focuses on social equity education, employee engagement, and strategies to improve diversity and inclusion on GLY’s projects. Her three young sons inspire her daily to feel empowered, to work hard, and to make time for fun.
